Topobathymetric Digital Elevation Models (DEM) for Flood Modeling in the Carolinas

Topobathymetric Digital Elevation Model (DEM) were created by merging multiple high-resolution LiDAR and survey data extracted from HEC-RAS models. The DEMs use a UTM coordinate reference system, have units of meters and are relative to NAVD88. The data is provided the data in raster format (TIF) and with spatial resolutions of 5 and 20 meters. These datasets incorporate channel data of various complexities using the best available data for improved 2D flood modeling.
