Topcal21 is designed to solve any topographic surveying problem. Its tools are user-friendly, enabling you to solve any difficulty when working in Surveying. TopCal 21 works under Windows Operative System of 32 bits. Now it works with projects in a way that allows having different tasks organized in folders and it can handle several points and observations file at once. It has a new view that will display the data in a calculation sheet. All its tools are presented with dialog boxes that will guide the user to complete the computations. The output data is in ASCII or HTML format, allowing as well DXF, DGN, ASCII for Digi and BIN for Digi.
TopCal 21 has a lot of tools:
- Computation of triangulations and trilaterations.
Intersections.
- Two points Resections and three points resections.
- Computation of Hansen’s problem.
- Computation of orientations.
- Traverses.
- COGO.
- Surface and area computing.
- Generation of drawings from points.
- Coordinate transformation between different reference systems.
- Automatic sketch generation.
- Computation of profiles.
- Cut and fill computation.
- Least square compensation for networks.
- Computation of levelling networks.
- Import and export from a lot of topographic instruments formats (Leica, Trimble, Nikon, Sokkia, etc.)
- Computation of random errors (accidental errors).
- Computation of systematic errors.
- Several tools to compute geometric problems
