Abstract Aerial photo mosaics of the Yellowstone River corridor. Images may be a mix of years from 1948 to 1951, in MrSID format. These images range in size from 2 to 43 megabytes.These images were georeferenced to 1995 U.S. Geological Survey Digital Orthophoto Quadrangles. Positional accuracy was targeted on the river corridor. Little effort was made to reference the upland areas in regions of high relief.In general, there is one image for each county, from Sweet Grass, Montana, to McKenzie, North Dakota. Yellowstone County is divided into 2 images.Some older GIS applications may need .sdw files to accompany these files for georeferencing information. ESRI's ArcMap needs .aux files to read the coordinate system of the images from. These files may be accessed at https://ftpgeoinfo.msl.mt.gov/Data/Spatial/NonMSDI/Collections/Yellowstone_River_Clearinghouse/Imagery/1950/aux_and_sdw.zip.The cell size of the images varies from 1 to 2.5 meters: McKenzie - 1.879 Richland - 1.823 Dawson - 2.394 Prairie - 1.882 Custer - 2.462 Rosebud - 1.853 Treasure - 1.790 Yellowstone - 1.000 Stillwater - 1.000 Sweet Grass - 1.000
Purpose Developed as part of the Yellowstone River Cummulative Effects Study. Imagery is intended for reach level analysis of changes in the Yellowstone River Corridor.
