Orthophotography is digital aerial photography that has been geometrically corrected or “orthorectified”, meaning the images show objects on the ground in their true scale and geographic position. Measurements of distances, angles and areas can be taken directly from the orthophotos. Commonly used to monitor changes in land cover over time and as an accurate background image in the production of maps, digital orthophotography is important reference data used with Geographic Information System (GIS) software.
The regional coverage areas acquired have expanded or shifted from year to year depending on available funding and the interest areas of funding contributors, so to see if imagery in a particular format is available for your area of interest (AOI) and year, you can check the map viewer below and email us with the details of your request.

Most ortho-imagery in this section can also be downloaded directly from the RGIS website managed by the Earth Data Analysis Center at the University of New Mexico.
