'Total Station' in surveying integrates:
Choose the correct answer
Only horizontal angle measurement
Theodolite (angles) + EDM (distance) + microprocessor — single instrument gives 3D coordinates from one setup
GPS and barometric altimeter only
Camera and distance measurement for photography only
Correct Answer
B. Theodolite (angles) + EDM (distance) + microprocessor — single instrument gives 3D coordinates from one setup
Why is this the answer?
Total station: combines: (1) Theodolite (horizontal and vertical angles); (2) EDM (Electronic Distance Measurement — distance to prism); (3) Microprocessor (computes coordinates, stores data, uploads to computer). Single setup: measures angle + distance → computes 3D point coordinates (E, N, elevation). Replaces: separate theodolite + chain/tape. Modern: robotic total station (auto-targets prism), scanning total station (no prism for short range). IS 8486 part covers field procedures.
