GeoHECHMS
GeoHECHMS speeds up watershed modeling by automating subbasin delineation, Curve Numbers, and Time of Concentration calculations. As an advanced data wrapper to industry-standard HEC-HMS, it simplifies workflows and accelerates common hydrologic preprocessing tasks needed for HEC-HMS modeling. Engineers use its AutoCAD-compatible interface to pull land use and soil data, compute TR 55/TR-20 parameters and simplify pre- and post-development scenarios for seamless detention/retention pond design.
Plex-Earth
Plex-Earth is your geospatial go-to tool in CAD. Satellite and aerial imagery, years of historical archives, and 3D terrain, all inside your drawing. Built for AEC teams across civil engineering, solar, wind, telecom, oil & gas, and utilities, it integrates into AutoCAD, Civil 3D, Map 3D, and BricsCAD. Choose from basemaps including Google Maps, Azure Maps, and OpenStreetMap for general reference, or bring in premium imagery from Nearmap, Vexcel, Hexagon, Airbus, and Vantor when the project demands higher resolution and defensible source data.
