Waypoint bearing and range
Drawn at its real position, dimmed when occluded by terrain.

AR navigation is not a novelty on a screen you were already looking at. It answers one question a two-dimensional map answers badly: which of those five identical ridgelines is the one I am supposed to cross.

02 / How it works
The mechanism, not the promise.
- Pose from sensors
- Camera orientation is fused from the compass, gyroscope and accelerometer, corrected against terrain features where they are unambiguous.
- Terrain mesh
- Elevation is decoded from Terrain-RGB tiles into a mesh, which is what lets an overlay sit behind a ridge instead of floating in front of it.
- Occlusion
- A waypoint on the far side of a ridge is drawn dimmed rather than as if it were in front — the single thing that makes AR navigation trustworthy.
- Party overlay
- Group member positions, received over mesh where there is no cellular, drawn in the camera view at their real bearing and range.
- Offline
- The mesh and the overlay come from the downloaded region. AR works in the places you need it, which are the places with no signal.
03 / Capabilities
What you actually get.
Party positions in view
Where your group actually is, in the direction you are looking.
Terrain annotation
Slope angle and aspect sampled at the point you are aiming at.
3D route preview
Fly the planned line over the terrain mesh before you walk it.
Hillshade and relief
The same DEM drives both the 3D view and the 2D shaded relief, so they never disagree.
Honest about hardware
AR quality depends on the handset's sensors. The app tells you when the pose confidence is low instead of drawing a confident wrong overlay.
04 / Process
Traced, node by node.
Every node in this graph names the file it came from, so the diagram can be audited against the codebase rather than taken on trust.
Which ridge? That one.
