Statewide Color Photographs
U.S. Farm Services Agency National Agricultural Imagery Program (NAIP), 1-meter resolution. NAIP is the National Agricultural Imagery Program administered through the U.S. Department of Agriculture's Farm Production and Conservation Business Center (FPAC-BC) Geospatial Enterprise Operations (GEO) Branch.
These photos have been compressed from the original quarter-quad tiles and provided in the MrSID MG3 or MG4 format which is a compressed file format to allow for easier data transfer. MrSID MG4 is supported in ArcGIS 10.1 and newer.
The downloadable products are multi-band images with three visible and one near-infrared wavelength bands, and an alpha band for identifying no-data areas.
Most software will automatically display the first three bands as a natural-color image.
To view the imagery as color infrared (CIR or false color), use band four as the red image, band one as the green, and band two as the blue.
Click on a county in the map below to download the 3 or 4-band county mosaic images of the area, or download the county mosaic images directly from the ftp site.
