Digital
Orthophoto Imagery
The
GEMI Store carries a large selection of digital orthophotography
at various resolution levels for most of the major cities
in the US. Let us be your source for all your imagery
needs. Digital orthophoto imagery has been georeferenced
using a digital elevation model (DEM). Orthorectified
imagery is the only imagery which is as accurate as
a map at the same scale. Distortion from the camera
and from local terrain has been taken out of the image.
