资源简介：
The dataset is a digital elevation model (DEM) for a 20-km reach of the Missouri River downstream from Wolf Point, MT. Channel topography was generated from data collected by USGS staff from the Columbia Environmental Research Center during single-beam sonar surveys of the channel bed in June 2018 and terrestrial light detection and ranging (LiDAR) surveys of channel banks in September 2018. Floodplain topography was generated from airborne LiDAR data collected in November 2012 by Furgo Horizons, Inc. for the U.S. Army Corps of Engineers.
