Description
Hey everyone,I wanted to share what I have been working on recently. I had this itch for a long time to figure out if terrain contour matching could help with ground navigation, by only only relying on iphone's sensors and public data. So far I have had decent results. This is a working prototype, but there is a lot that is in the pipeline. If you notice anything weird, let me know or open a PR. Any feedback, comments are welcome :)

Could you build this?
No Terrain contour matching (TERCOM) and dead-reckoning navigation on edge mobile sensors in GPS-denied environments involves advanced sensor fusion, Kalman filtering, and geospatial signal processing.
What it would actually take: The system requires an iOS app (Swift/C++) integrating data from the barometer, IMU (accelerometer/gyroscope), and magnetometer with high-resolution digital elevation models (DEM) stored offline. The core technical hurdle is real-time terrain contour matching (TERCOM/SITAN algorithms) and extended Kalman filtering to bound inertial sensor drift without GPS ground-truth references. Building this requires specialized aerospace, geomatics, and robotics estimation expertise.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
