About this course

Every modern total station runs coordinate geometry under the hood. This lecture shows how horizontal (E, N) and vertical (Z) coordinates are computed, how set-station and set-orientation work, and how resection recovers an unknown instrument position from angles, from coordinates and in three dimensions.

Horizontal and vertical coordinate computation
Set station and set orientation explained
Resection by angles, by coordinates and 3-D two-point resection
