App Profile: 測量 座標計算

This application employs the reverse traverse method used in construction.
Simply using this application onsite will relieve you from the effort of pointless calculations with a scientific calculator by calculating numbers for you.

[Reverse Traverse Method]
By inputting the XY coordinates of the instrument and backsight points, then inputting unspecified XY coordinates, the contained angle and distance will be calculated.
Elevation can also be calculated.
