Abstract These are Black and White visible-band orthophotos showing two disconnected reaches of the Yellowstone River in Park County. The upper reach runs approximately 20 miles from Gardiner north to the US 89 Bridge, and the lower reach runs about 16 miles from a point about 6 miles northeast of Livingston to a point 2.75 miles east of the county line. The photos were taken on April 11, 1999 and the pixel resolution is 2 feet.
Purpose These orthophotos were created as part of a multi-agency flood plain study of the Upper Yellowstone River, extending along approximately 80 miles of the river. Partners include the US Army Corps of Engineers, USDA Forest Service Northern Region and the Montana Department of Natural Resources and Conservation.
Supplemental Information Here is some information provided about the original photography. The current layer consists of 9 images selected from the data described below, converted to Montana State Plane Coordinates: This data set contains a series of twenty digital orthophotos that follow the course of the Yellowstone River, extending from approximately four miles north of Springdale, Montana, to Gardiner, Montana. We used six strips of 24000 black and white photography flown parallel with the river and oriented the orthophotos along the axis of flight. Each orthophoto measures 13200 feet in X and 27250 feet in Y and overlaps the next in sequence by a minimum of two thousand feet. Significant overlap occurs between strips. The orthophotos are in the Montana State Plane South Zone coordinate system, 1927 North America Datum. Each digital image is in Tagged Image File Format, approximately 200 MB in size, and has a two foot ground resolution.
