The base module, with more functions than the step-in products Topocad Reader/+ and Topocad engineer, is a complete CAD package made for surveying, mapping, and design. Functions that bring your field data to a map or drawing for publishing.

Communication and Survey Calculation

Topocad communicates to field computers and field format files whether it is serial communication, by PC card, or using the implemented applications from the total station/GPS vendors. We communicate with Trimble, Leica, Topcon and Sokkia instruments and with all kinds of file formats. Topocad handles data to and from total stations (survey raw data or local coordinates), levellers, and GPS instruments; both GPS vectors and lat/long data.

Data is calculated, processed, and/or transformed to the drawing.  Point codes and geometry are taken care of and you will get a result in your drawing or map better than you imagined. Topocad handles numerous different methods for lining, radius, splines, closed, and filled surfaces etc.

CAD

The CAD is our own engine.  The CAD platform has numerous functions for creation and modification of objects; whether there are points, lines, surfaces, polygons, symbols, texts, raster files, etc.

In the base module we have implemented transformation of vectors and raster files. There is also a strong output function for creation of your drawings and maps including functions for legends, insertion of several views, coordinate grid, and adjustment of the drawing view.

The File Format and Communication

The CAD format TOP is a hybrid between the surveyors coordinate files, the drawing formats like DWG, DGN, and GIS file formats with their typical attribute data. This means that you will not loose any data going to Topocad’s TOP file.

We import and export many different file formats as co-ordinate files, drawing files, and GIS files.

Digital Terrain Model

The base module includes the DTM creation and modification and together with this contouring.

Road Lining

The base module also includes road line file format, road line editing, and calculation and many commands to compare points against a road line.
