Minnesota Air Photos - FSA, USDA: 2004
Through the National Agricultural Imagery Program (NAIP), the Farm Service Agency collects color imagery used to monitor U.S. Department of Agriculture farm programs. Other organizations and citizens use NAIP photos for countless other applications.
2004 NAIP georectified photos
Most of Minnesota was flown in Summer 2004. Only the areas that were missed in 2003 were processed to 1-meter orthorectified photos; the remaining areas were processed to 2-meter georectified specifications. The 2004 1-meter orthos have been combined with the 2003 orthophotos to create single county MrSID mosaics with complete coverage over each county.
MrSID format photos are available for all Minnesota counties; all areas are 2-meter georectified.
- Download selected county files in MrSID format. FSA has provided the following county mosaics to the Land Management Information Center for free online distribution since these counties contain areas that were not flown in 2003: Aitkin, Brown, Carlton, Clay, Cook, Cottonwood, Itasca, Jackson, Kanabec, Lake, Mille Lacs, Morrison, Redwood, Renville, St. Louis and Watonwan. These may be partial county files and may not completely fill the gaps in the 2003 data.
- Download remaining county files free from USDA's Data Gateway

NAIP 2004 Aerial Photography, Minnesota: MrSID County Files, Interim Version
From links in the table below, download selected county mosaics of NAIP 2004, Interim (National Agricultural Imagery Program) aerial photography in MrSID format. The mosaics were created for the U.S. Department of Agriculture, Farm Service Agency compliance program.
Replacement files are available for counties with areas not flown in 2003; these areas are being filled with 2004 imagery. As of 1/6/06, available counties are: Brown, Carlton, Cottonwood, Itasca north, Redwood and St. Louis. View on Minnesota Geospatial Commons.
For interim 2004 files on this webpage, MnGeo has only those counties that contain areas that could not be flown in 2003. See a map of the missing areas. All other 2004 interim county files must still be ordered from FSA. Note that these files may not include all of the area within a county, and they may not include all of the areas that were not flown in 2003. The final county file versions should be more complete.
Interim product
All of the 2004 MrSID county files on this page are an interim version. They are 2-meter resolution, so they will not be as detailed as the one-meter resolution photos available for 2003 (on the plus side, the files are much smaller). To compare, click on the example photos below, each showing the same area of rapids along the St. Louis River in Carlton County (note that the color balance was also different for the different years).
