Aerial Photos of Montana, 2019
USDA Farm Service Agency - National Agricultural Imagery Program (NAIP) 2019
The 2019 NAIP imagery includes gaps in coverage where the acquisition was interrupted due to weather conditions. NAIP imagery in the missing areas was collected in the summer of 2020. A map showing areas collected in each year can be found here.
Click on a county in the map below to download the 4-band county mosaic images of the area, or download the county mosaic images directly from the ftp site.
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.
