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
