A New Generation of Maps
Adapted from USGS website
 
The "Digital Map – Beta" is the first step toward a new generation of digital topographic maps delivered by the U.S. Geological Survey. These maps are built from The National Map data, which are integrated from local, state, federal, and other sources.
 
The initial version of the "Digital Map – Beta" includes orthoimagery plus roads and geographic names in the traditional 7.5 minute quadrangle format. "Digital Maps - Beta" are available free on the Web in GeoPDF format. File size is about 15 to 20 megabytes.
 
Tools are available free for download. Users can turn data layers on and off, zoom in and out, and print the maps. As the "Digital Map - Beta" evolves, the USGS will add historical versions of the topographic maps and will incorporate other data layers including hydrography and contours. Use of the term "Beta" signifies that these maps are initial versions that do not yet contain the full content of the traditional USGS topographic quadrangle maps.
 
What Makes The USGS "Digital Map - Beta" Different From Other Electronic Maps?
  • Richer content….more than a street map
  • Can be used on the computer or plotted and printed to scale
  • Looks and feels like the legacy paper USGS topographic maps with user-selected layers
  • Nationally consistent data; quality assured to standards
  • Can be downloaded free from the USGS Store
  • User interaction tools can be downloaded free
  • Users can select from various reference systems: Latitude/Longitude, UTM (Universal Transverse Mercator), and MGRS (Military Grid Reference System)
  • Direct "mash-up" capabilities with Google Maps®
  • Will continue to evolve and incorporate additional data layers including contours
The USGS values your comments and suggestions about the new "Digital Map - Beta".
