• 英文介紹
• GWNSURF is an ideal application for surface modeling and mapping projects. GWNSURF is a world class surface modeling package, with advanced contouring, profiling and slope analysis capabilities. GWNSURF is available as an AutoDesk or MicroStation addon providing a lowcost surface modeling application option which runs inside AutoCAD or MicroStation. GWNSURF 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 GWNDTM users can also analyze specific features, evaluate cut and fill and design powerful presentations.
• Use of the unique GIS Quadtree approach ensures GWNSURF is able of processing an unlimited number of data points with minimal system requirements. Clients have reported using GWNSURF to complete calculations of over 1,000,000 points in a single file with no delays or "bogging down" of computer.
• GWNSURF (Surface Modeler) utilizes the same powerful engine that drives the GWNDTM—Digital Terrain Model. GWNSURF can be operated in MicroStation and AutoCAD with a multitude of platforms. GWNSURF also gives users the full range of MicroStation and AutoCAD commands and menu options while running GWNSURF.
• GWNSURF (Surface Modeler) utilizes the same powerful engine that drives the GWNDTMÑDigital Terrain Model. GWNSURF can be operated in MicroStation and AutoCAD with a multitude of platforms (DOS, Windows 3.x/95/NT). All software is written with open architecture which lets users modify and customize the products to suit their specific requirements. GWNSURF also gives users the full range of MicroStation and AutoCAD commands and menu options while running GWNSURF.
• GWNSURF is based on a series of integrated microbased software modules which together in this software package provide powerful interactive contour mapping and design capabilities for civil engineering requirements to demanding users of many engineering, survey and mapping disciplines. This Surface Modeler is as industrially strong as the Digital Terrain Model (GWNDTM), uses the same engine, and provides many of the same features, giving a Project Manager assistance in keeping track of many projects. The Project Manager can then allow the user easy access in placing project files on any drive (YES! even network drives), providing a functional method of digital file organization.
• GWNSURF users can use existing terrain models and contour maps or build their own terrain models. Visualization of terrain models can be viewed in dynamic 2D or 3D format from any point of view. It allows users to utilize a vertical exaggeration scaling factor to more easily visualize differences in ground surface models generated. GWNSURF allows creation of contours by userdefined increments (English or Metric), choice of contour line thickness/color/color banding, the ability to smooth/weed contours within a userdefined corridor and label contours either above, below or in the contour line (userdefined text font/size/color). Terrain models can be created from a variety of data which can be polygonized and clipped. Terrain models can be queried and draped. Alignments can be created. Graphical presentations of profiles can be generated. Slope analysis can be produced.
• GWNSURF offers a surfacetosurface method of volumetric calculation, slope area and drainage area analysis. Pad shoulder designs can be generated with projection to surface. Linear elements can be stationed along the pad design for establishing extra data points for more accurate volumetric calculations. Volume reports can be automatically generated.
