TerraSurvey handles data from field surveying with total stations and GPS. It reads-in survey data from text files and creates a survey drawing as 3D design file. It recognizes automatically a number of survey data formats that are produced for example by Trimble, Leica or Sokkia surveying instruments. By defining your own file format you can read-in practically any files, which are organized in columns and contain coordinate or angle values.
For processing the survey data in TerraSurvey, each survey point is assigned a feature code, which identifies the surveyed object, for example a tree, a man hole cover, an elevation point or points along a road center line. The graphical display for each object is defined by one or more drawing rules. Several options for displaying the data in list or table views help the user to do modifications or fix errors in the data.
TerraSurvey is a useful addition to TerraModeler for creating TINs from survey elements. An optional sub-code for each survey element is used by TerraModeler for recognizing automatically the modelling information for this element and determines whether it is included into the terrain model as a random point, breakline or not at all.
If you use TerraSurvey in combination with TerraPhoto and TerraScan you can improve the absolute accuracy of image positions in an image list by using ground control points from TerraSurvey. You can also assign feature codes to vectorized objects such as power line wires or road break lines, which have been vectorized or digitized in TerraScan.
All together TerraSurvey is a drawing tool for feature coded survey data and, in combination with TerraScan and TerraModeler, it enables the use of such survey data for terrain modelling and other mapping tasks.
TerraSurvey Lite is a light mapping application for field surveyors and other users who don't need all functions of the full version.
