Hybrid bathymetric-topographic digital elevation model for the Missouri River at Searcys Bend, near Columbia, Missouri
Description
The dataset contains a hybrid bathymetric-topographic digital elevation model (DEM) of the Missouri River at Searcys Bend, near Columbia, Missouri. The DEM was generated within ArcGIS by compositing bathymetric data from multiple single and multibeam sonar surveys collected between September 2019 and July 2021 with previously existing topographic data collected from airborne LiDAR into a triangulated irregular network (TIN). The resulting TIN was then manually edited and exported as a raster for use in developing a hydrodynamic model.
