Original drivers for creating an electronic Topographic Map Collection Historical quadrangles can serve as chronological layers supplementing the new US TOPO Documents the changes over time. 4
Original reasons for converting this Collection • Long-term record and documentation of the natural, physical and cultural landscape. • The potential for analysis of distribution and spatial patterns is invaluable throughout the sciences and non-science disciplines. • For more than 125 years, the USGS topographic mapping program has accurately portrayed the complex geography of our nation. 5
Creating a comprehensive catalog • These maps are either long forgotten or are not known to have existed. • Most are no longer available for distribution in print. • No single complete set is known to exist – anywhere. 6
USGS Map collection 7
Goals for historical USGS quadrangle scanning ü Scan approximately 180, 000 printed quadrangles – all maps, all scales. Historical quads are all printed maps prior to US TOPO. ü Use consistent, high quality specifications ü Provide all editions, all scales ü Georeference the maps ü Release through the USGS Store and The National Map Viewer 8
Goals for historical USGS quadrangle scanning ü A complete copy of all metadata and digital files will be available from USGS. ü Copies will be housed at the National Archives and Records Administration as well as the Library of Congress, Geography and Maps Division. ü Copies of pertinent segments of the collection may be housed in local map libraries, research institutes and other government offices. ü All files will be in the public domain. 9
