Topographical Maps and Mapping Data

The U.S. Geological Survey produces multicolored topographic maps using contours to show the shape and elevation of terrain. These topographic maps also show and name prominent natural and cultural features. The largest scale topographic map series is 1: 24,000, known as the 7.5-minute topo quadrangle map series. Philadelphia County is covered by ten 7.5-minute topo quad sheets.

These image files, or digital raster graphics [DRGs], are faithfully reproduced digital images of original sourcemaps, scanned at a minimum resolution of 250 dpi. These files, produced by the USGS and distributed through Pennsylvania State University's Pennsylvania Spatial Data Access program, are TIFF-format images.


US GeoData. United States Geological Survey website.
FTP-downloadable mapping data, consisting of several data resources:
  • Digital Elevation Model [DEM] 1:250,000-scale and 7.5-minute
  • Digital Line Graphs [DLG] 1:2,000,000-scale, 1:100,000-scale, and Large Scale (1:24,000-scale)
