AR Theodolite: Angle & GPS

▶ Turn your phone into an outdoor survey multi-tool. Aim the camera and a live overlay shows azimuth, pitch angle, level and GPS position right on the scene, so you read the field without juggling separate instruments.

▶ Measure the horizontal and vertical angle between two points by sighting each one. Estimate distance and height with trigonometry from your eye height and the target angles.

▶ Read your position in the format you work in: latitude and longitude in decimal or DMS, plus UTM and MGRS grids used worldwide. Switch true north and magnetic north as needed.

▶ Capture a photo with the heading, angle and coordinates stamped on it, a clean record for the site. Save station notes and reuse them later.

▶ Everything runs on device with no region data, so it behaves the same anywhere. Calibrate the compass for a steadier reading before you start.

Results are field estimates based on your phone's sensors and are not a substitute for professional survey equipment. Confirm critical measurements with proper instruments.
