Abstract The data consists of elevation information stored as ESRI TIN (triangulated irregular network) datasets. There are 37 of these TINs in the first phase of the mapping project, and each covers an area between 3 and 6 miles long.
Purpose These data were created as part of a joint Yellowstone River Conservation District Council and U.S. Army Corps of Engineers, Omaha District cumulative impacts study of the Yellowstone River channel and floodplain. The multi-agency interdisciplinary planning study extends 477 river miles from Sweetgrass County, Montana to the Missouri River confluence in McKenzie County, North Dakota. These data are specifically intended to provide an accurate digital surface model (topographic and bathymetric) with which to analyze the hydraulic conditions of the Yellowstone River channel and floodplain. The TINs were created to operate within the ArcGIS software environment. In addition, they are intended to serve as a base for the project GIS and also to support a wide variety of analyses including planimetric data extraction (e.g., infrastructure, riverine geomorphology, land cover, habitat and vegetation), and to monitor long-term river channel changes. The first phase of the mapping focused on Stillwater, Yellowstone and Dawson Counties in Montana and included approximately 295 square miles of floodplain, together with 130 river miles of channel bathymetry.
