  Description:
    Abstract: This data set represents raw, 2-foot bare earth contours (isolines) for the Little Suncook River unit. The data set was extracted from a regional elevation contour data set derived from the Coastal New Hampshire LiDAR collection (2011). Prior to contour generation, the regional LiDAR raster was "smoothed" using the ArcGIS "Focal Statistics" tool using a 3x3 circular neighborhood. The contours were generated using the ArcGIS "Contour" tool while applying a Z factor of 3.2802 to convert the elevation values from meters to feet. Once generated, contours less than 1 meter in length were deleted.
    Purpose: These 2-foot contours were developed for visual use and comparison with other GIS data sets. The suitability for technical, scientific, or other finished cartographic purposes is unknown and should not be assumed.
    Supplemental_Information: A companion data set representing smoothed versions of the raw contours is also available for GRANIT, recommended for cartographic use only.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: The critical attribute of this data is the contour elevation, the absolute accuracy of which has been affected by a number of processing steps. The original LiDAR elevation deliverables had a 2 meter or better nominal post spacing (2m GSD) and a a bare earth vertical accuracy of 15.0 centimeters RMSEz or better. Prior to contouring, the input raster was "smoothed" using a 3x3 circular neighborhood. The original elevation units of meters were converted to feet using a factor of 3.2808.
    Quantitative_Attribute_Accuracy_Assessment:
      Attribute_Accuracy_Value: Floating point
      Attribute_Accuracy_Explanation: None
  Logical_Consistency_Report: It is possible that individual contour lines cross one another in areas of complex or steep terrain. Polyline topology was not used to evaluate or fix this possible issue.
  Completeness_Report: Contour line segments less than 1 meter in length have been deleted.

    Process_Step:
      Process_Description:
        Final processing included 1) clipping the regional contour data set by HUC10, 2) projecting each HUC10 data set from UTM to NH State Plane feet, NAD83, and 3) clipping the HUC10 data sets by HUC12.
        (The original plan was to distribute the data by HUC10, but the large file sizes (in excess of 500 GB) were considered too large for web distribution.  Once this finding was discovered, it was more expedient
        to re-clip from the HUC10 data sets.)
