Orthoimagery

The GeoCommunity has one of the largest online collections of orthoimagery available in the world. We have nearly complete US coverage of 1m USGS DOQQs and DOQQ county mosaics; extensive coverage of USDA National Agriculture Imagery Program (NAIP) imagery 1m and/or 2m county mosaics (2003 through 2010!); and nearly complete worldwide coverage of 14.5m, year 2000 Landsat imagery. So whatever your area of interest is - we've got you covered!

Data can either be written to a CD/DVD or downloaded via the premium data download mechanism.

US DATA BUNDLES on CD/DVD ORTHOIMAGERY STATE BUNDLES Color or Black and White OrthoImagery data bundles for the majority of US States are available. Both USDA National Agriculture Imagery Program (NAIP)imagery and USGS DOQQ data is available. Generally the files are 1 meter images compressed in MrSid format, but we also have some sub-meter resolution imagery. Projections vary, see coverage graphics for each state.

INTERNATIONAL DATA BUNDLES on CD/DVD LANDSAT MOSAICS BUNDLE The GeoCommunity now has nearly complete worldwide coverage of Orthorectified 2000 Landsat Enhanced Thematic Mapper Mosaics and 1990 Landsat Thematic Mapper Mosaics. The mosaics are in MrSid format and in a UTM projection. Click here for more information and to download individual Landsat mosaics!
