Abstract This data set contains imagery from the National Agriculture Imagery Program (NAIP). These data are digital aerial photos, at 60 centimeter resolution, of most of the state of Montana, taken in 2019. Due to snow cover the imagery acquisition was not completed in 2019 and some areas were acquired in 2020. https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Imagery/2019_NAIP/NAIP2019CollectionYear.jpg - The data are available from the State Library in several formats: - Online viewing as either natural-color or false-color infrared images at https://montana.maps.arcgis.com/apps/instant/imageryviewer/index.html?appid=8692589b6bc34a978c6ffd2dadbc62ab - View the 4-band (infrared, red, green, blue) map service at https://gisservicemt.gov/ArcGIS/rest/services/MSDI_Framework/NAIP_2019/ImageServer - Download the 4-band compressed county mosaics in MrSID format at https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Imagery/2019_NAIP/UTM_County_Mosaics/ - Request the data from the State Library as a collection 11,775 4-band (near infrared, red, green and blue) TIF images in UTM coordinates. Each image is about 400 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/2019_NAIP/NAIP_2019_MT_tileindex_CurrentlyAvailable.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.

Purpose
Supplemental Information The NAIP program is administered by U.S. Department of Agriculture Farm Services Agency and has been established to support two main FSA strategic goals centered on agricultural production. These are, increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs. Ortho imagery provides an effective, intuitive means of communication about farm program administration between FSA and stakeholders. New technology and innovation is identified by fostering and maintaining a relationship with vendors and government partners, and by keeping pace with the broader geospatial community. As a result of these efforts the NAIP program provides three main products: DOQQ tiles, Compressed County Mosaics (CCM), and Seamline shape files. The Contract specifications for NAIP imagery have changed over time reflecting agency requirements and improving technologies. These changes include image resolution, horizontal accuracy, coverage area, and number of bands. In general, flying seasons are established by FSA and are targeted for peak crop growing conditions. The NAIP acquisition cycle is based on a minimum 3 year refresh of base ortho imagery. The tiling format of the NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 pixel buffer on all four sides. NAIP quarter quads are formatted to the UTM coordinate system using the North American Datum of 1983. NAIP imagery may contain as much as 10% cloud cover per tile. Since 2009, all NAIP imagery acquisition contracts used an accuracy specification such that the imagery is to match reference imagery within a ground surface distance of 6 meters.
