ABOUT

TopoSuite is an application for land surveyors running on Android 4.0.3 and later versions. It is useful for determining new geographical points based on measurements and it offers various calculations possibilities.

Here is a list of supported calculations:

• Polar calculations
  • station orientation
  • free station
  • polar survey
  • polar implantation
  • axis implantation
• Orthogonal calculations
  • orthogonal survey
  • orthogonal tracking
  • orthogonal implantation
• Intersections calculations
  • lines intersection
  • circles intersections
  • line / circle intersections
• Surfaces calculations
  • surface included with arc of a circle
  • parallel limit displacement regarding compulsory surface
• Miscellaneous
  • field / distance
  • point projection on a line
  • circle computation using three points
  • arc of a circle segmentation
• Mathematics
  • triangle solver
  • circular elements resolution

Data, such as points, may be imported into the application. Supported input files are CSV (with ";" as a separator for now), LTOP and PTP. The list of points can be exported to CSV and shared through e-mail, etc.

It is currently available in English and French (German planned).

LIMITATIONS

This program has been developed in accordance with rules that are valid for land surveying in Switzerland (angles are determined in gradian, lengths are in meters and distance/surface results are rounded to the fourth decimal for instance).
