Aerial Photos of Montana, 2015
U.S. Farm Service Agency - National Agricultural Imagery Program (NAIP)
2017 Update: The 2016 supplement to the 2015 NAIP, which completes coverage for Montana, will be available on or around June 15, 2017. The tiles below are presented without the supplement, although the county mosaic tiles do include the supplement.
The 2015 NAIP was not completed for some areas of Montana due to cloud cover, wildfire smoke, and snow cover. This map shows the imagery that was collected.
Click on a square in the map below to download the photograph of the area. Most of the images are about 150 megabytes in size.
These photos are in MrSID MG4 format and Montana State Plane coordinates, units meters, datum NAD83(HARN). 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 photos are multi-band images with three visible and one near-infrared wavelength, and an alpha band for identifying no-data areas. Most software will automatically display the first three bands as a natural-color image. To see a traditional false-color infrared image, use band four as the red image, band one as the blue, and band two as the green.
The data may be accessed through the State Library's web map services. The images may be viewed in your web browser. The data may be downloaded as large natural-color compressed county mosaics, which do include the 2016 supplement covering Montana completely.
The tiles below do not include the 2016 supplement at this time.
