Description:
Abstract:
This data set contains point locations identifying image center points for the Rockingham/Strafford County 1974 orthoimagery available through GRANIT. The point locations and most of the associated attribute information were generated using ESRI scripting (AML) tools to query each individual image.
Purpose:
These photo center points are intended as a tool to identify individual image files and to retrieve their physical characteristics. The data are part of a larger effort, sponsored by the Cooperative Institute for Coastal and Estuarine Environmental Technology (CICEET) at the University of New Hampshire, to analyze past and current development trends and their impact on water quality, and to model future development pressures in the region and their likely water quality impacts.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The key attributes were digitally generated based on coordinate/file structure information associated with the photo images.
Logical_Consistency_Report: Topology exists.
Completeness_Report: Data are included for all photos.
Positional_Accuracy:

Horizontal_Positional_Accuracy_Report: Data were digitally generated from orthorectified photographs.
Lineage:
Process_Step:
Process_Description:
Center point locations for individual tiffs were generated by retrieving image information via the ARC &describe command and deriving each point location in Arcedit. Additionally, the geometry attribute fields (X-coordinate, Y-coordinate, min/max coordinates for the image, and no. of rows and columns) were populated with data returned by the &describe command. Text columns were extracted from the photo name, and/or manually entered into the database based on documentation provided with the photography.
