USDA Natural Resources Conservation Service 2003 Helena, Montana Montana State Library ftp://ftp.geoinfo.msl.mt.gov/Data/Spatial/NonMSDI/Collections/Yellowstone_River_Clearinghouse/Imagery/2001_IR/ Aerial color infrared photo mosaics of the Yellowstone River corridor. The image resolution is one meter and they are in MrSID format. The images were collected between August 3 and August 6, 2001. These images range in size up to 155 megabytes. There is a pair of images for each county, from Sweet Grass to the confluence with the Missouri River. The same image for each county is available in UTM zone 13 coordinates and in Montana State Plane coordinates. Photo dates on a county-by-county basis are McKenzie and Richland on 8/5/2001, Dawson on 8/3/2001 and 8/5/2001, Prairie, Custer, Rosebud, and Treasure on 8/3/2001, Yellowstone on 8/2/2001 and 8/3/2001, Stillwater on 8/2/2001 and 8/6/2001, and Sweet Grass on 8/2/2001. All images were obtained during the day between 9 AM and 3 PM. The project was commissioned by the Lower Yellowstone River District Council as a basis for resources inventory and monitoring. 20010803 20010806 ground condition Complete None planned -110.28 -103.91 48.03 45.53 ISO 19115 Topic Category imageryBaseMapsEarthCover Historic Imagery Yellowstone River Aerial Photography air photo orthophoto orthoimage orthoimagery infrared color IR Yellowstone River Montana North Dakota McKenzie Richland Dawson Prairie Custer Rosebud Treasure Yellowstone Stillwater Sweet Grass None The Montana State Library provides this product/service for informational purposes only.

Photgraphs contained 25 percent overlap, therefore, every other frame was scanned. The scanned imagery was then processed using ERDAS Imagine 8.4. Imagery was orthorectified using ERDAS/ OrthoBase. USGS digital orthophotography was used as the horizontal reference source and 30 meter digital elevation models were used as the vertical reference source. The U.S. Geological Survey camera report was used to obtain the interior and exterior orientation and other specific camera information needed in Orthobase. Ground control points and tie points were created. Nearest neighbor resampling method was employed to produce an orthorectified image. Once orthorectified, the imagery was clipped to within approximately one mile on either side of the Yellowstone River centerline of flow using an area of interest (AOI). Images were then mosaiced using ERDAS mosaic tool. The overlap function was set for no cutlines and overlay. Image matching was not performed. Mosaiced images were compressed at a 20:1 ratio with MrSID geospatial encoder 1.4. 1 1 meters North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 Montana State Library mailing address
