GWN-SURF
Surface Modeling, Mapping & Design
GWN-SURF is an ideal application for surface modeling and mapping projects. GWN-SURF is a world class surface modeling package, with advanced contouring, profiling and slope analysis capabilities. GWN-SURF is available as an AutoDesk or MicroStation add-on providing a low-cost surface modeling application option which runs inside AutoCAD or MicroStation. GWN-SURF can be used to visualize terrain models in dynamic 3D or 2D format, including vertical exaggeration scaling for better differentiation. It also provides powerful features for volume calculations and slope and drainage area analysis. With GWN-DTM users can also analyze specific features, evaluate cut and fill and design powerful presentations.
Use of the unique GIS Quadtree approach ensures GWN-SURF is able of processing an unlimited number of data points with minimal system requirements. Clients have reported using GWN-SURF to complete calculations of over 1,000,000 points in a single file with no delays or "bogging down" of computer.
GWN-SURF (Surface Modeler) utilizes the same powerful engine that drives the GWN-DTM—Digital Terrain Model. GWN-SURF can be operated in MicroStation and AutoCAD with a multitude of platforms. GWN-SURF also gives users the full range of MicroStation and AutoCAD commands and menu options while running GWN-SURF.
