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).  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 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.
