Tasks like merging DEMs, generating elevation profiles, or building HEC-RAS floodplain surfaces are completed in half the time. The software integrates LiDAR surveying data, NLCD Land Cover data, and FEMA Flood maps directly into AutoCAD, MicroStation, or ArcGIS workflows. GeoHECRAS is used for river modeling, 1D and 2D hydraulic modeling, dam breach analysis, and HEC-RAS bridge modeling, along with complex floodplain encroachment studies—all with built-in reporting and reduced external GIS dependency.
