Aerial Photos of Montana, 2017
USDA Farm Service Agency - National Agricultural Imagery Program (NAIP)
The 2017 NAIP product currently includes a few gaps in coverage. The missing areas are scheduled to be collected in the summer of 2018.
Click on a county in the map below to download the County mosaic images of the area.
These images have been compressed from the original quarter-quad tiles and are provided in MrSID MG4 format and Universal Transverse Mercator (UTM) coordinates, units meters, datum NAD83. MrSID MG4 is supported in ArcGIS 10.1 and newer. Users of older mapping software may need to download a plug-in to allow you to view MG4 images or contact your software vendor. The imagery was collected at a spatial resolution of 60 centimeters, with each pixel measuring roughly two feet on the ground.
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.
