Description:
Abstract:
This data set is a mosaic of county digital soil surveys and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information.

This data set consists of georeferenced digital map data and computerized attribute data. The map data include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. The descriptive attributes were populated from the National Soil Information System relational database using the NRCS Soil Data Viewier and default aggregation methods, which gives the proportionate extent of the component soils and their properties.

The county surveys may not be edge matched to adjacent SSURGO certified soil surveys.

Purpose:
SSURGO depicts information about the kinds and distribution of soils on the landscape. The soil map and data used in the SSURGO product were prepared by soil scientists as part of the National Cooperative Soil Survey.
Supplemental_Information:
Digital versions of hydrography, cultural features, and other associated layers that are not part of the SSURGO data set may be available from the primary organization listed in the Point of Contact.

Use_Constraints:
The U.S. Department of Agriculture, Natural Resources Conservation Service, should be acknowledged as the data source in products derived from these data.

This data set is not designed for use as a primary regulatory tool in permitting or citing decisions, but may be used as a reference source. This is public information and may be interpreted by organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application. Federal, State, or local regulatory bodies are not to reassign to the Natural Resources Conservation Service any authority for the decisions that they make. The Natural Resources Conservation Service will not perform any evaluations of these maps for purposes related solely to State or local regulatory programs.

Photographic or digital enlargement of these maps to scales greater than at which they were originally mapped can cause misinterpretation of the data. If enlarged, maps do not show the small areas of contrasting soils that could have been shown at a larger scale. The depicted soil boundaries, interpretations, and analysis derived from them do not eliminate the need for onsite sampling, testing, and detailed study of specific sites for intensive uses. Thus, these data and their interpretations are intended for planning purposes only. Digital data files are periodically updated. Files are dated, and users are responsible for obtaining the latest version of the data.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute accuracy is tested by manual comparison of the source with hard copy plots and/or symbolized display of the map data on an interactive computer graphic system. Selected attributes that cannot be visually verified on plots or on screen are interactively queried and verified on screen. In addition, the attributes are tested against a master set of valid attributes. All attribute data conform to the attribute codes in the signed classification and correlation document and amendment(s).
Logical_Consistency_Report:
Certain node/geometry and topology GT- polygon/chain relationships are collected or generated to satisfy topological requirements (the GT-polygon corresponds to the soil delineation). Some of these requirements include: chains must begin and end at nodes, chains must connect to each other at nodes, chains do not extend through nodes, left and right GT-polygons are defined for each chain element and are consistent throughout, and the chains representing the limits of the file are free of gaps. The tests of logical consistency are performed using vendor software. All internal polygons are tested for closure with vendor software and are checked on hard copy plots. All data are checked for common soil lines (i.e., adjacent polygons with the same label). Edge locations generally do not deviate from centerline to centerline by more than 0.01 inch.

The county surveys may not be edge matched to adjacent SSURGO certified soil surveys.

Completeness_Report:
A map unit is a collection of areas defined and named in terms of their soil components or miscellaneous areas or both. Each map unit differs in some respect from all others in a survey area and each map unit has a symbol that uniquely identifies the map unit on a soil map. Each individual area, point, or line so identified on the map is a delineation.

Soil Scientists identify small areas of soils or miscellaneous areas that have properties and behavior significantly different than the named soils in the surrounding map unit. These minor components may be indicated as special features. If they have a minimal effect on use and management, or could not be precisely located, they may not be indicated on the map.

A map unit has specified kinds of soils or miscellaneous areas (map unit components), each with a designated range in proportionate extent. Map units include one or more kinds of soil or miscellaneous area. Miscellaneous areas are areas that have little or no recognizable soil.

Specific National Cooperative Soil Survey standards and procedures were used in the classification of soils, design and name of map units, and location of special soil features. These standards are outlined in Agricultural Handbook 18, Soil Survey Manual, 1993, USDA, NRCS; Agricultural Handbook 436, Soil Taxonomy, 1995, USDA, NRCS; and all Amendments; Keys to Soil Taxonomy, (current issue) USDA, NRCS; National Soil Survey Handbook, title 430-VI,(current issue) USDA, NRCS.

The actual composition and interpretive purity of the map unit delineations were based on data collected by scientists during the course of preparing the soil maps. Adherence to National Cooperative Soil Survey standards and procedures is based on peer review, quality control, and quality assurance. Quality control is outlined in the memorandum of understanding for the soil survey area and in documents that reside with the Natural Resources Conservation Service state soil scientist. Four kinds of map units are used in soil surveys: consociations, complexes, associations, and undifferentiated groups.

Consociations - Consociations are named for the dominant soil. In a consociation, delineated areas use a single name from the dominant component in the map unit. Dissimilar components are minor in extent. The soil component in a consociation may be identified at any taxonomic level. Soil series is the lowest taxonomic level. A consociation that is named as a miscellaneous area is dominantly that kind of area and minor components do not significantly affect the use of the map unit. The total amount of dissimilar inclusions of other components in a map unit generally does not exceed about 15 percent if limiting and 25 percent if nonlimiting. A single component of a dissimilar limiting inclusion generally does not exceed 10 percent if very contrasting.

Complexes and associations - Complexes and associations consist of two or more dissimilar components that occur in a regularly repeating pattern. The total amount of other dissimilar components is minor extent. The following arbitrary rule determines whether complex or association is used in the name. The major components of an association can be separated at the scale of mapping. In either case, because the major components are sufficiently different in morphology or behavior, the map unit cannot be called a consociation. In each delineation of a complex or an association, each major component is normally present though their proportions may vary appreciably from one delineation to another. The total amount of inclusions in a map unit that are dissimilar to any of the major components does not exceed 15 percent if limiting and 25 percent if nonlimiting. A single kind of dissimilar limiting inclusion usually does not exceed 10 percent.

Undifferentiated groups - Undifferentiated groups consist of two or more components that are not consistently associated geographically and, therefore, do not always occur together in the same map delineation. These components are included in the same named map unit because their use and management are the same or very similar for common uses. Generally they are grouped together because some common feature, such as steepness, stoniness, or flooding, determines their use and management. If two or more additional map units would serve no useful purpose, they may be included in the same unit. Each delineation has at least one of the major components, and some may have all of them. The same principles regarding the proportion of minor components that apply to consociations also apply to undifferentiated groups. The same principles regarding proportion of inclusion apply to undifferentiated groups as to consociations.

Minimum documentation consists of three complete soil profile descriptions that are collected for each soil added to the legend, one additional per 3,000 acres mapped; three 10 observation transects for each map unit, one additional 10 point transect per 3,000 acres.

A defined standard or level of confidence in the interpretive purity of the map unit delineations is attained by adjusting the kind and intensity of field investigations. Field investigations and data collection are carried out in sufficient detail to name map units and to identify accurately and consistently areas of about 4 acres.

Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The accuracy of these digital data is based upon their compilation to base maps that meet National Map Accuracy Standards at a scale of 1 inch equals 1,000 feet. The difference in positional accuracy between the soil boundaries and special soil features locations in the field and their digitized map locations is unknown. The locational accuracy of soil delineations on the ground varies with the transition between map units.

For example, on long gently sloping landscapes the transition occurs gradually over many feet. Where landscapes change abruptly from steep to level, the transition will be very narrow. Soil delineation boundaries and special soil features generally were digitized within 0.01 inch of their locations on the digitizing source. The digital map elements are edge matched between data sets. The data along each quadrangle edge are matched against the data for the adjacent quadrangle. Edge locations generally do not deviate from centerline to centerline by more than 0.01 inch.

Process_Description:
Carroll County: The soil map units were observed and documented by NRCS Soil Scientists. Correlation decisions were made by the New Hampshire staff and approved by MLRA office MO-12. (Process Date: 2002-2005)

Changes to the original digitized soil survey were made and map unit boundaries were refined and transferred to the digitized image. On screen digitizing was done using digital orthoimagery background. Soil map unit delineations were recompiled and redigitized on screen by the New Hampshire soils staff. (Process Date: 2002-2005)

The soil symbols and delineations were edited, digitized, edge matched, and quality control performed by NRCS staff. (Process Date: 2006)

NASIS tabular data was developed by Natural Resources Conservation Service soil scientists according to national standards. (Process Date: 2006)

NRCS Missouri Digitizing Unit staff reviewed the spatial data for adherence to SSURGO standards and made edits as necessary using ArcInfo 9.1. (Process Date: 2006)

The Natural Resources Conservation Service State Soil Scientist or delegate, upon completion of data quality verification, determined that the tabular data should be released for official use. A selected set of map units and components in the soil survey legend was copied to a staging database, and rating values for selected interpretations were generated. The list of selected interpretations is stored in the database table named sainterp. (Process Date: 20060920)

The Natural Resources Conservation Service State Soil Scientist or delegate verified that the labels on the digitized soil map units link to map units in the tabular database, and certified the joined data sets for release to the Soil Data Warehouse. A system assigned version number and date stamp were added and the data were copied to the data warehouse. The tabular data for the map units and components were extracted from the data warehouse and reformatted into the soil data delivery data model, then stored in the Soil Data Mart. The spatial data were copied to the Soil Data Mart without change. (Process Date: 20060922)

Process_Description:
Cheshire County: Field procedures for the second order soil survey included plotting of soil boundaries determined by field observations and by interpretation of remotely sensed data. Boundaries were verified at closely spaced intervals, and the soils in each delineation were identified by traversing and transecting the landscape. Soil scientists described and sampled the soils, analyzed the samples in the laboratory, and statistically analyzed the data. The classification and map unit names were finalized at the final correlation in January 1985. (Process Date: 1989)

The field maps were manually compiled to 1:20,000 one-third quadrangle film positives. The soil delineations were digitized by Complex Systems Research Center (CSRC) at the Institute for the Study of Earth, Oceans and Space, University of New Hampshire. A high accuracy (.003 inch resolution) CALCOMP digitizing board was used with ARC/INFO version 6.0 software to perform the digitizing. Four control points corresponding to the four corners of the one-third quadrangles were used for registration, and a RMS threshold of .003 was applied. Spatial accuracy was verified by overlaying checkplots of the digitized data on the source quadrangles. Map unit codes and point codes were also verified on the plotted overlays. In addition, a domain check was performed, to ensure that all codes in the digital data were legitimate for the county. Quality control and edge matching were performed first by CSRC staff, and then by NRCS staff. (Process Date: 1996)

The one-third quadrangles were merged into a full 7.5 minute quadrangle format and appended into a seamless county data layer. The data were transfered to 8mm tape by CSRC and delivered to the NRCS. The digital data were projected from the New Hampshire State Plane coordinate system to the Universal Transverse Mercator coordinate system NAD27, Zones 18 and 19, by NRCS staff using ARC/INFO version 7.0 software. They were then processed to separate 7.5 minute quadrangle coverages and exported to DLG-3 optional format. NRCS performed a final review of the digital plots with the source orthophotographs. (Process Date: 1997)

The NRCS, Soils Section, Richmond, Virginia, imported the data for verification in ARC/INFO 7.1.2. Pseudo nodes were removed from all quadrangles and other minor edits were made. New DLG's reflecting these changes were written with ARC/INFO 7.1.2. (Process Date: 1998)

The attribute data were downloaded from the Map Unit Intepretation Records database (MUIR) residing in the New Hampshire State Soil Survey database. This database is maintained by the New Hampshire Soils Specialist in charge of the database, according to the standards of the National Cooperative Soil Survey. (Process Date: 1997)

The SSURGO database of Cheshire County, New Hampshire was downloaded from U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center (NCGC) distribution site for the purpose of updating the tabular information from the SSSD version SSURGO 1, to the NASIS 5.2 version SSURGO 2. The data were then run through the 20040211 ReCert AMLs provided by NCGC and submitted to the Soil Data Warehouse for archival and distribution. (Process Date: 2004)

Process_Description:
Coos County: The Coos County, New Hampshire, soil survey was published in 1943 by the U.S. Department of Agriculture, Bureau of Chemistry and Soils. The mapping scale was 1:62,500. The survey was evaluated in the 1950's and did not meet modern standards. (Process Date: 1950)

Field mapping procedures were carried out between 1956 and 1998 to bring the soil survey to current National Cooperative Soil Survey standards. The survey was conducted at two levels of intensity. Open areas, agricultural land, areas of glacial outwash, major stream valleys and glacial till areas not managed for industrial forestry were mapped at the Order 2 level. Heavily forested areas owned by paper companies were mapped at the Order 3 level. At the Order 2 level of mapping, the soils in each delineation were identified by field observation and by remotely sensed data. Boundaries were verified at closely spaced intervals. At the Order 3 level, soil boundaries were plotted by observation and interpretation of remotely sensed data. Soil boundaries were verified by transversing representative areas and by transecting. Soil scientists described and sampled the soils, analyzed samples in the laboratory, and statistically analyzed the data. The classification and map unit names were finalized at the final correlation in June 1999. The portion of Coos County, New Hampshire that lies within the White Mountain National Forest was excluded from this survey. (Process Date: 1999)

1:24,000 ratioed film positives of the 1:15,840 and 1:20,000 scale field maps were used along with the 1:24,000 field maps of the soil map unit delineations and special soil features for manual compilation to the 1:24000 scale analog orthophotographic 1/3 quadrangles. (Process Date: 1999)

Complex Systems Research Center (CSRC) staff used the following five steps to automate the Coos County soil survey, provided by the U.S. Department of Agriculture, Natural Resources Conservation Service (NRCS):

1. Soil units and point features were manually digitized, using a CALCOMP digitizing board, and coded using Arc/Info 8.0 software. The four annotated map corners were used for registration, and a RMS threshold of .002 was applied. Initial Quality Assurance (QA) was conducted by CSRC staff by manually comparing the digital data on hard copy plots to the source atlas sheets. Final QA of individual atlas sheets was performed by NRCS, using the same method.

2. Soil units were dissolved using the Arc/Info 8.0 DISSOLVE command to find and correct common soil lines (i.e. adjacent polygons with the same map unit symbol).

3. A domain check was conducted to insure the validity of map unit symbols. This was completed by digitally comparing the map unit symbols to a master legend, provided by NRCS.

4. The individual atlas sheets were edge matched to ensure soil unit boundaries meet at neatlines, and soil units were again dissolved. NRCS used hard copy plots, provided by CSRC, to find and correct any discrepancies between adjacent atlas sheets.

5. The individual atlas sheets were combined to form two countywide, final coverages. 1) Soil units were combined to form a final polygon coverage using the Arc/Info 8.0 MAPJOIN command. 2) Point features were combined to form a final point coverage using the Arc/Info 8.0 APPEND command. A final dissolve and domain check was conducted on the final polygon coverage, before both data sets were provided to the NRCS in ARC Export format. Data automation procedures complied with existing CSRC and SSURGO standards. (Process Date: 2002)

The seamless ArcInfo export files and metadata were submitted by the U.S. Department of Agriculture, Natural Resources Conservation Service, New Hampshire State Office and were evaluated at the USDA/NRCS Wisconsin Digitizing Unit in Madison, Wisconsin. The data were evaluated in ARC/INFO, Version 7.2.1 software with SSURGO evaluation routines provided by U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center, Fort Worth, Texas (NCGC). Upon successful completion of the SSURGO certification AMLs, the data were submitted to the Soil Data Warehouse for archival and distribution. (Process Date: 2005)

Process_Description:
Grafton County: The Grafton County, New Hampshire, soil survey was published in 1939 by the U.S. Department of Agriculture, Bureau of Chemistry and Soils. The mapping scale was 1:62,500. The survey was evaluated in the 1950's and did not meet modern standards. (Process Date: 1950)

Field mapping procedures were carried out between 1950 and 1986 to bring the soil survey to current National Cooperative Soil Survey standards. The survey was conducted at two levels of intensity. Open areas, agricultural land, areas of glacial outwash and major stream valleys were mapped at the Order 2 level. Heavily forested areas, areas with high local relief and paper company land were mapped at the Order 3 level. At the Order 2 level of mapping, the soils in each delineation were identified by field observation and by remotely sensed data. Boundaries were verified at closely spaced intervals. At the Order 3 level, soil boundaries were plotted by observation and interpretation of remotely sensed data. Soil boundaries were verified by transversing representative areas and by transecting. Soil scientists described and sampled the soils, analyzed samples in the laboratory, and statistically analyzed the data. The classification and map unit names were finalized at the final correlation in August 1987. The portion of Grafton County, New Hampshire that lies within the White Mountain National Forest was excluded from this survey. (Process Date: 1987)

Ratio film positives of the 1:15,840 scale photographs were used to manually compile to the 1:20,000 scale one-third quadrangle orthophotographs. Special soil features were compiled onto the same base material. (Process Date: 1988)

The soil maps were automated by Complex Systems Research Center (CSRC) at the Institute for the Study of Earth, Oceans and Space, University of New Hampshire. A high accuracy (.003 inch resolution) CALCOMP digitizing board was used with ARC/INFO software to perform the digitizing. The four annotated map corners were used for registration, and a RMS threshold of .003 was applied. Data were captured as polygons (for soil units) and as points (for special soil features, e.g. gravel pits). Map unit codes and point codes were entered into the associated database. Spatial accuracy was verified by overlaying plotted output of the automated data on the source orthophotograph. Standards required the digitized line work to be within 40 feet (in ground units) of the source line work. Map unit codes and point codes were also verified on the plotted overlays. In addition, a domain check was performed to ensure that all codes in the digital data were legitimate for the county. Map sheet review was performed first by CSRC staff and then by NRCS staff. Upon acceptance of the individual map sheets, the sheets were edgematched and appended into a seamless county data layer. NRCS performed a final review of the digital plots with the original orthophotographs. The NRCS, National Cartography and Geospatial Center, SSURGO Support Section, imported the data for verification in ARC/INFO 7.0.2. The data were reformatted to 7.5 minute format. The data were edited to correct soil line mismatches across neat lines, extra vertices in the neat line, mislabeled areas, and digitizing errors. DLGs reflecting these changes were written with ARC/INFO 7.0.4. (Process Date: 1992)

The Map Unit Interpretation Records database was developed by Natural Resources Conservation Service soil scientists according to national standards. (Process Date: 1995)

Process_Description:
Hillsborough County East: Field procedures for the 1:20,000 second order soil survey included plotting of soil boundaries determined by field observations and by interpretation of remotely sensed data. Boundaries were verified at closely spaced intervals, and the soils in each delineation were identified by traversing and transecting the landscape. Soil scientists described and sampled the soils, analyzed the samples in the laboratory, and statistically analyzed the data. The classification and map unit names were finalized at the final correlation in 1979. (Process Date: 1981)

The soil delineations and symbols from the field maps were manually recompiled to mylar overlays, registered to 1:24,000 and 1:25,000 orthophotographs. The final publication negatives were used to develop ratioed film positives at the 1:24,000 and 1:25,000 scales. (Process Date: 1990)

The soil symbols and delineations were digitized by Complex Systems Research Center (CSRC) at the Institute for the Study of Earth, Oceans and Space, University of New Hampshire. The high accuracy (.003 inch resolution) CALCOMP digitizing board was used with ARC/INFO version 6.0 software to perform the digitizing. The four annotated map corners were used for registration, and a RMS threshold of .003 was applied. Spatial accuracy was verified by overlaying plotted output of the digitized data on the source orthophotoquad. Map unit codes and point codes were also verified on the plotted overlays. In addition, a domain check was performed for all codes in the digital data. Quality control and edge matching were performed by both CSRC and Natural Resources Conservation Service (NRCS) staff. A quality join was created along the county boundary by NRCS staff. (Process Date: 1990)

The orthophotographs were merged and appended into a seamless county data layer. The digital data were transfered to 8mm tape by CSRC and delivered to the NRCS. The data were projected from the New Hampshire State Plane Coordinate System to the Universal Transverse Mercator Coordinate System, NAD27, Zone 19, by NRCS staff using ARC/INFO version 7.0 software. They were then processed to separate 7.5 minute quadrangle coverages and exported to DLG-3 optional format. NRCS performed a final review of the digital plots with the source orthophotographs. (Process Date: 1997)

Special soil features were manually digitized to the soil feature and orthophotographic base. (Process Date: 1998)

The data were imported in ARC/INFO 7.1.2. A review was made of the data. Minor edits were made. New DLG's reflecting these changes were written with ARC/INFO 7.1.2. This work was performed by the Natural Resources Conservation staff in Richmond, Virginia. (Process Date: 1998)

The attribute data were downloaded from the Map Unit Intepretation Records database (MUIR) residing in the New Hampshire State Soil Survey database.

Process_Description:
Merrimack/Belknap Counties: Field procedures for the second order soil survey included plotting of soil boundaries determined by field observations and by interpretation of remotely sensed data. References used were the USGS topographical maps and old soil surveys of Merrimack Co. (published 1965) and Belknap Co. (published 1968). Boundaries were verified at closely spaced intervals, and the soils in each delineation were identified by traversing and transecting the landscape. Soil scientists described and sampled the soils, analyzed the samples in the laboratory, and statistically analyzed the data. (Process Date: 2004)

The field maps were manually compiled to 1:24,000 full quadrangle film positives in NAD27. (Process Date: 2004)

The data were sent to the U.S. Department of Agriculture, Natural Resources Conservation Service, Wisconsin Digitizing Unit, Madison, Wisconsin (WIDU). The annotated soil delineation overlays were sent to Midwest Graphics, Kenosha, Wisconsin for raster scanning at 250 dpi on an Intergraph Anatach scanner in tiff uncompressed format. The tiff files were geo-referenced to a digital full quad index using ArcGIS 8.3 ArcMap. The raster scanned data were imported into LT2000 version 1.0 maps. Once all the scanned soil lines were added to the maps, a county border was added. The soils and special soil features were digitized on screen from the annotated soil delineations tiff files in LT2000 at a resolution of 0.01 inch. The raster editing, labeling, edge-matching, and vector conversion were done in LT2000. Check plots of the soils and special soil features were reviewed by a soil scientist and cartographic staff at the WIDU. The soils and special soil features data were run through a series of LT2000 macros for correctness and completeness. These macros smoothed and thinned out line work, added nodes for every 3000 vertices, added corner nodes and snapped nodes across the neatlines. The soils and special soil features data were then exported as Digital Line Graph-3 Optional format files (DLGs) in LT2000. The DLGs were evaluated with the modified Oct. 1998 ARC/INFO SSURGO Evaluation AMLs provided by U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center, Fort Worth, Texas (NCGC). The DLG?s were imported to ARC coverages. The full quad coverages were merged together into a seamless full county coverage and projected to NAD83, UTM zone 19. The coverages were than mailed to New Hampshire for review and editing. The coverage was reviewed and edited in NH by soil scientists. The perimeter of soil survey was seamlessly joined with each surrounding soil survey area. (Process Date: 2005)

The coverages were imported to a Geodatabase using ArcGIS 9.2. The data was reviewed and edited in NH by soil scientists. The perimeter of soil survey was seamlessly joined with each surrounding SSURGO certified soil survey area. (Process Date: 2007)

The geodatabase was mailed to the Wisconsin Digitizing Unit in Madison, Wisconsin. The data were then exported to polygon, line, and point coverages using ArcCatalog. Next, the data were then projected to Geographic coordinates in decimal degrees and run through the 20040524 ReCert AMLs provided by NCGC.

Soil map unit delineations and special soil features were manually recompiled to the 1:20000 scale analog orthophotographic quadrangles. Errors from the published soil survey were corrected and map unit boundaries were refined as needed to the orthophotographic image. (Process Date: 1995)

The soil symbols and delineations were digitized by Complex Systems Research Center (CSRC) at the Institute for the Study of Earth, Oceans and Space, University of New Hampshire. The high accuracy (.003 inch resolution) CALCOMP digitizing board was used with ARC/INFO Version 6.0 software to perform the digitizing of soil delineations and the soil survey boundary area. The four annotated map corners were used for registration and a RMS threshold .003 was applied. Spatial accuracy was verified by overlaying the plotted output of the digitized data on the source orthophotographic quadrangle. Map unit codes and point codes were also verified on the plotted overlays. In addition a domain check was performed for all codes in the digital area. Quality control and edge matching were performed by both CSRC and Natural Resources Conservation Service staff. (Process Date: 1996)

Special soil features were manually digitized using ArcView Version 3.0 software to the digital orthophotographic quadrangle base at a resolution of at least 0.01 inch by NRCS staff. The digital data were merged and appended into a seamless county data layer. The digital data were transferred to an 8 mm tape by CSRC and delivered to the U.S. Department of Agriculture, Natural Resources Conservation Service staff.

The DLGs, metadata, and tabular data were sent to U.S. Department of Agriculture, Natural Resources Conservation Service, Wisconsin Digitizing Unit, Madison, Wisconsin (WIDU) for SSURGO Evaluation. The DLG-3 Optional format files were evaluated with the 1998 ARC/INFO SSURGO evaluation AMLs provided by USDA-NRCS National Cartography and Geospatial Center (NCGC). Spatial data were digitally displayed over 1992 digital orthophoto quadrangles (DOQs) and an irregular shifting was identified. ArcEdit Version 7.2.1 was to correct this shifting. Links and anchors were methodically added to a full county coverage using 1992 DOQs as a background and referencing the published soil survey. The "adjust" command in ARC was then used to relocate the lines to a more accurate position. Plots were made with the adjusted lines overlaying the DOQs and a quality control check was performed by New Hampshire soil scientists. The full county soils coverage was then split back into 7.5 minute quadrangle format and plots were made with the special soil features to insure their accuracy. Once the accuracy of the special soil features was determined the coverages were rerun through the SSURGO AMLs. Upon successful completion of SSURGO evaluation, the SSURGO generated DLGs and NASIS SSURGO download tabular data were processed with the April 2001 archiving AMLS provided by NCGC. The certified data were ftped to NCGC for archival and distribution. (Process Date: 2002)

The survey was rearchived due to a processing error that caused an empty polygon to be created. Windham quadrangle was altered. (Process Date: 2003)

The SSURGO database of Rockingham County, New Hampshire was downloaded from U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center (NCGC) distribution site for the purpose of updating the tabular information from the SSSD version SSURGO 1, to the NASIS 5.2 version SSURGO 2. The data were then run through the 20040524 ReCert AMLs provided by NCGC and submitted to the Soil Data Warehouse for archival and distribution. (Process Date: 2004)

The Natural Resources Conservation Service State Soil Scientist or delegate, upon completion of data quality verification, determined that the tabular data should be released for official use. A selected set of map units and components in the soil survey legend was copied to a staging database, and rating values for selected interpretations were generated. The list of selected interpretations is stored in the database table named sainterp. (Process Date: 20041208)

The Natural Resources Conservation Service State Soil Scientist or delegate verified that the labels on the digitized soil map units link to map units in the tabular database, and certified the joined data sets for release to the Soil Data Warehouse. A system assigned version number and date stamp were added and the data were copied to the data warehouse.

Process_Description:
Strafford County: Strafford County had a previously published soil survey, 1978, at 1:15840 scale. An evaluation was made of the soil survey in 1989. It was determined that the soil map unit delineations and map unit components were accurate. (Process Steps: 1989)

Ratioed film positives, 1:24000 and 1:25000 scale, were made from the final publication negatives. Soil map unit delineations and special soil features were manually compiled from the ratioed film positives to an overlay registered to 7.5 minute orthophoto quadrangles. Errors from the published soil survey were corrected and map unit boundaries were refined as needed to the orthophotographic image. (Process Steps: 1989)

The soil symbols and delineations were digitized by Complex Systems Research Center (CSRC) at the Institute for the Study of Earth, Oceans and Space, University of New Hampshire. The high accuracy (.003 inch resolution) CALCOMP digitizing board was used with ARC/INFO Version 6.0 software to perform the digitizing. The four annotated map corners were used for registration, and a RMS threshold of .003 was applied. Spatial accuracy was verified by overlaying plotted output of the digitized data on the source orthophotoquad. Map unit codes and point codes were also verified on the plotted overlays. In addition, a domain check was performed, for all codes in the digital data. Quality control and edge matching was performed by both CSRC and NRCS staff. A quality join was created along the soil survey boundary by NRCS staff. (Process Steps: 1990)

Special soil features were manually digitized to the orthophotoquad base at a resolution of at least 0.01 inch by NRCS staff. (Process Steps: 1998)

The orthophotographs were merged and appended into a seamless county data layer. The digital data were transferred to 8mm tape by CSRC and delivered to the NRCS. The data were projected from the New Hampshire state plane coordinate system to the Universal Transverse Mercator coordinate system North American Datum of 1927, Zone 19, by NRCS staff using ARC/INFO Version 7.0 software. It was then processed to separate 7.5 minute quadrangle coverages and exported to DLG-3 optional format. NRCS performed a final review of the digital plots with the source orthophotos. (Process Steps: 1998)

The DLGs, metadata, and tabular data were sent to U.S. Department of Agriculture, Natural Resources Conservation Service, Wisconsin Digitizing Unit, Madison, Wisconsin for SSURGO Evaluation. The DLG-3 Optional format files were evaluated with the October 1998 ARC/INFO Evaluation AMLs provided by U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center, Fort Worth, Texas. Upon successful completion of the SSURGO Evaluation, the DLGs were rechecked with the October 1998 ARC/INFO SSURGO Evaluation AMLs.

Attribute_Label: DrainClass
Attribute_Definition:
Drain Class. "Drainage class (natural)" refers to the frequency and duration of wet periods under conditions similar to those under which the soil formed. Alterations of the water regime by human activities, either through drainage or irrigation, are not a consideration unless they have significantly changed the morphology of the soil. Seven classes of natural soil drainage are recognized-excessively drained, somewhat excessively drained, well drained, moderately well drained, somewhat poorly drained, poorly drained, and very poorly drained. These classes are defined in the "Soil Survey Manual."

Drain Class was populated by Complex Systems Research Center, University of New Hampshire using the NRCS Soil Data Viewer and the dominant condition aggregation method and default settings.

Attribute_Label: HydrolGrp
Attribute_Definition:
Hydrologic Soil Group. Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms.

The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Hydrologic Soil Group was populated by Complex Systems Research Center, University of New Hampshire using the NRCS Soil Data Viewer and the dominant condition aggregation method and default settings.

The soil surveyor uses parent material to develop a model used for soil mapping. Soil scientists and specialists in other disciplines use parent material to help interpret soil boundaries and project performance of the material below the soil. Many soil properties relate to parent material. Among these properties are proportions of sand, silt, and clay; chemical content; bulk density; structure; and the kinds and amounts of rock fragments. These properties affect interpretations and may be criteria used to separate soil series. Soil properties and landscape information may imply the kind of parent material.

For each soil in the database, one or more parent materials may be identified. One is marked as the representative or most commonly occurring. The representative parent material name is presented here.

Parent Material Name was populated by Complex Systems Research Center, University of New Hampshire using the NRCS Soil Data Viewer and the dominant condition aggregation method and default settings.

Attribute_Label: Slope
Attribute_Definition:
Representative Slope. Slope gradient is the difference in elevation between two points, expressed as a percentage of the distance between those points.

The slope gradient is actually recorded as three separate values in the database. A low value and a high value indicate the range of this attribute for the soil component. A "representative" value indicates the expected value of this attribute for the component. For this soil property, only the representative value is used.

Attribute:
Attribute_Label: HydrcRatng
Attribute_Definition:
Hydric Rating by Map Unit. This rating indicates the proportion of map units that meets the criteria for hydric soils. Map units are composed of one or more map unit components or soil types, each of which is rated as hydric soil or not hydric. Map units that are made up dominantly of hydric soils may have small areas of minor nonhydric components in the higher positions on the landform, and map units that are made up dominantly of nonhydric soils may have small areas of minor hydric components in the lower positions on the landform. Each map unit is designated as "all hydric," "partially hydric," "not hydric," or "unknown hydric," depending on the rating of its respective components.

"All hydric" means that all components listed for a given map unit are rated as being hydric, while "not hydric" means that all components are rated as not hydric. "Partially hydric" means that at least one component of the map unit is rated as hyric, and at least one component is rated as not hydric. "Unknown hydric" indicates that at least one component is not rated so a definitive rating for the map unit cannot be made.

Hydric soils are defined by the National Technical Committee for Hydric Soils (NTCHS) as soils that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (Federal Register, 1994). Under natural conditions, these soils are either saturated or inundated long enough during the growing season to support the growth and reproduction of hydrophytic vegetation.

The NTCHS definition identifies general soil properties that are associated with wetness. In order to determine whether a specific soil is a hydric soil or nonhydric soil, however, more specific information, such as information about the depth and duration of the water table, is needed. Thus, criteria that identify those estimated soil properties unique to hydric soils have been established (Federal Register, 2002). These criteria are used to identify map unit components that normally are associated with wetlands. The criteria used are selected estimated soil properties that are described in "Soil Taxonomy" (Soil Survey Staff, 1999) and "Keys to Soil Taxonomy" (Soil Survey Staff, 2006) and in the "Soil Survey Manual" (Soil Survey Division Staff, 1993).

If soils are wet enough for a long enough period of time to be considered hydric, they should exhibit certain properties that can be easily observed in the field. These visible properties are indicators of hydric soils. The indicators used to make onsite determinations of hydric soils are specified in "Field Indicators of Hydric Soils in the United States" (Hurt and Vasilas, 2006).

Overview_Description:
Entity_and_Attribute_Overview:
Map Unit Delineations are closed polygons that may be dominated by a single soil or miscellaneous area component plus allowable similar or dissimilar soils, or they can be geographic mixtures of groups of soils or soils and miscellaneous areas.

The map unit symbol uniquely identifies each closed map unit delineation. Each symbol corresponds to a map unit name. The map unit key is used to link to information in the National Soil Information System tables.

Map Unit Delineations are described by the National Soil Information System database. This attribute database gives the proportionate extent of the component soils and the properties for each soil. The database contains both estimated and measured data on the physical and chemical soil properties and soil interpretations for engineering, water management, recreation, agronomic, woodland, range, and wildlife uses of the soil.

The National Soil Information System database contains static metadata. It documents the data structure and includes such information as what tables, columns, indexes, and relationships are defined as well as a variety of attributes of each of these database objects. Attributes include table and column descriptions and detailed domain information.

The National Soil Information System database also contains a distribution metadata. It records the criteria used for selecting map units and components for inclusion in the set of distributed data.

Special features are described in the feature table. It includes an area symbol, feature label, feature name, and feature description for each special and ad hoc feature in the survey area.

Descriptive attributes were populated by Complex Systems Research Center, University of New Hampshire using the NRCS Soil Data Viewer and default aggregation methods.
