Description:

Abstract:

Index of USGS quarter-quadrangles (3.75 minute) covering Pennsylvania. The polygons are attributed with information pertaining to the USGS/PaGS Digital Orthophoto Quarter-Quad (DOQQ) imagery collection available for download through PASDA. Including dates of image acquisition for the complete NAPP II imagery collection (1993-1995) and imagery available as of April 2003 from the NAPP III collection (1999- ).

Purpose: Information and management of PASDA collection.

Process_Description:

Quarterquads shapefile was imported to Geodatabase format using ArcCatalog software (8.2). Flight date information was obtained from DOQQ .hdr files where available or through USGS EarthExplorer when necessary. Through a series of queries and joins performed using MS-Access 2000, this information was appended to the attribute tables
