Terrain Profiler

Terrain Profiler turns your Android phone into a simple terrain profiling tool. Walk a route and the app builds an elevation/slope profile in real time, helping you visualize how the ground rises and falls along the path.

What you can do

* Create a terrain/elevation profile by walking from start to finish
* See a clear chart of height changes and slopes as you move
* Run forward and return passes to compare results and reduce drift
* Save scans with a custom name and timestamp for later review
* Switch units (meters/feet) and tune calibration settings for your device

How it works
Terrain Profiler uses on-device motion tracking (AR) together with phone sensors (such as the barometer and IMU) to estimate relative height changes along your route and draw a smooth terrain profile.

Great for

* Quick on-site checks of surface slopes and grade changes
* Planning and documenting routes, paths, and site conditions
* Construction and field work where a fast “good-enough” profile is useful

Important note about accuracy
This app provides approximate, relative measurements. Results depend on the device model, sensor quality, lighting conditions, and how you walk the route. Terrain Profiler is not a certified surveying instrument.

Permissions

* Camera: required for AR tracking (to understand motion and surfaces)
* Sensors: used to estimate height changes and improve stability
