Abstract:
USGS Historical Quadrangle in GeoPDF.
The USGS Historical Quadrangle Scanning Project (HQSP) is scanning all scales and all editions of topographic maps published by the U.S. Geological Survey (USGS) since the inception of the topographic mapping program in 1884. This map is provided as a general purpose map in GeoPDF for users who are not GIS experts.

Process_Step:
Process_Description:
The GeoPDFs for the scanned Historical Quadrangles are produced using the following steps. Historical Quadrangles are scanned typically at 600 PPI (minimum of 400 PPI). Metadata is collected from the information printed in the map collar. Scanned TIFF images are georeferenced to the original map datum, and reprojected to the original map projection. The final GeoPDF file is generated using TerraGo Publisher for Raster software. To support the use of the GeoPDF file in the U.S. Army Geospatial Center GeoPDF seamless viewing tool, neatline coordinates are added to the GeoPDF header file. Last, an FGDC compliant XML metadata file is generated and attached to the GeoPDF. Note that GeoPDF is a copyrighted format, with implementation rights held exclusively by TerraGo Technologies.
