Abstract:
This data set contains imagery from the National Agriculture Imagery Program (NAIP). These data are digital aerial photos, at 60 centimeter resolution, of the state of Montana, taken in 2021. The data are available from the State Library in two different formats. The most accessible format is a downloadable collection of compressed county mosaic (CCM) 4-Band MrSID images. These data are in UTM coordinates.
The FTP folder containing these images is https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Imagery/2021_NAIP/UTM_County_Mosaics
The data are available from the State Library as a collection 11,776 4-band (near infrared, red, green and blue) TIFF images in UTM coordinates. Each image is about 425 megabytes. The tiling format of the TIFF imagery is based on 3.75 x 3.75 minute quarter-quadrangles with a 300 pixel buffer on all four sides. An ESRI shapefile index showing the extent and acquisition dates of the TIF images is available at https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Imagery/2021_NAIP/NAIP2021_Index_Final_UTMZone12.zip
To order TIFF images from the State Library, select the quadrangles you want from the tiff index shapefile and send them to the Library, along with a storage device of sufficient size to hold them and return postage for the device. More information on ordering can be found at the following website https://msl.mt.gov/geoinfo/data/Aerial_Photos/Ordering
