TerraSurvey suits for field surveying with total stations and GPS as well as to control and improve the quality of laser data.
TerraSurvey reads-in survey data as text files and creates a survey a 3D design file. It recognizes automatically a number of survey data formats from Trimble, Leica etc. By defining your own file format you can read-in practically any files, which are based on coordinate or angle fields.
Each survey point is assigned a feature code, which defines the surveyed object. The graphical display of each code is defined by one or several drawing rules. The user can create new codes and drawing rules or modify existing ones and finally save them as code library.
TerraSurvey forms a nice combination to TerraModeler for creating TINs automatic from survey elements. Therefore each feature code may have also sub-code, which tells how TerraModeler is going to use the survey points in terrain modelling. So when TerraModeler scans the mapping elements coded by TerraSurvey, it recognizes automatic the modelling information and decides whether the point is a random point, breakline or does the point at all belong to any model.
If you use TerraSurvey with TerraPhoto and TerraScan you can calculate the best shift for orthoimagemosaic to respond the location of surveyed ground signals. You can also give feature codes to vectorized objects like power wires and road lines, which may have been detected by TerraScan. This may be very helpful, when one tries to export the data to databases and other systems than MicroStation.
