The 10 meter National Elevation Data (NED) is currently the only available statewide elevation data for Montana. Subsets of the statewide ten meter NED elevation rasters, slopes, slopes classified for rangeland planning, and 40 foot contour data have been created for Montana NRCS management areas and can be downloaded here.
The NAIP data for the state of Montana is available for the following collection periods: 2023, 2021, 2019, 2017, 2015, 2013, 2011, 2009, and 2005. Data resolution for the 2021, 2019, and 2017 collections is 60 cm. The 2015-2016 images are one meter resolution. All collections include 4-bands, 3 natural color and 1 near infrared. Due to variable weather conditions during the collection period gaps may occur in the NAIP tiles.
