USGS Digital Orthophoto Quarter Quadrangles (DOQQs)
Select the U.S. Geological Survey (USGS) quadrangle you want to download photographs
for by selecting its name from the list or by clicking its location on the map.
We compressed and mosaicked the four quarter-quadrangle images we received from
USGS for each quadrangle into a single MrSID image. Each compressed quadrangle is
about 8 megabytes in size. The MrSID images are available for every quadrangle in
State Plane coordinates (NAD83) and many quadrangles are also available in UTM coordinates
would like to thank the agencies that made this service possible.
