Topography On the Fly is a suite of land surveying tools. It allows you to have complex surveying calculations on the field quickly with maximum accuracy. The design is as simple as needed under work pressure. The advantage is that can be used only with a simple total station or additionally with more complex instruments and gps.

Angular units : gradians (default) and decimal degrees (degrees only in Distance/Azimuth).

Task list:
Direct geodetic problem
Inverse geodetic problem
Simple forward intersection
Two points resection – Free station
Simple resection
Inaccessible points
Line-line intersection
Line-circle intersection
Azimuths intersection
Tacheometry
Circles overlap
Trigonometric leveling

Great tool for land surveyors, civil engineers, topographers and land engineers.
