Abstract These data are color digital aerial photos, taken in the year 2009. They consist of 2,733 12x12-kilometer tiles that cover the entire state of Montana. They are orthorectified natural-color MrSID images with a ground resolution of 1 meter, and they are registered to the Montana State Plane coordinate system, NAD83, units meters.An ESRI shapefile showing the dates the images were collected is available at https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Imagery/2009_NAIP/naip_2009_dates.zip and a shapefile showing the extents and names of the 12-kilometer tiles is at https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Imagery/2009_NAIP/naip_2009_tile_index.zip.The imagery are also available via a web service at https://gisservicemt.gov/arcgis/rest/services/MSDI_Framework/NAIP_2009/ImageServer.The data were provided by the U.S. Farm Services Agency National Agricultural Imagery Program (http://www.apfo.usda.gov) as Compressed County Mosaics (CCMs) in UTM coordinates. These mosaics are available at https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Imagery/2009_NAIP/UTM_County_Mosaics/. The State Library clipped and mosaiced the CCM data to form these tiles and converted them to State Plane coordinates. The uncompressed TIFF images that the data were derived from are available from the State Library on request. Each of the 11,793 TIFF images covers a quarter of a USGS 7.5 minute quadrangle and is about 170 megabytes in size.
Purpose These aerial photographs were captured to support various governmental, municipal, tribal, and emergency management Geographic Information System activities. Orthorectified aerial photographs can be used to determine the geographic location of objects visible on the photos. The original imagery was acquired to meet USDA program requirements including conservation planning and soil survey.
