OpenAthena is a legacy Python tool that estimates a ground target’s location from drone camera metadata and terrain elevation. Its principal workflow extracts image position and camera orientation, loads a GeoTIFF elevation model, resolves the camera’s line of sight against terrain, and reports target coordinates; it can also publish Cursor on Target (CoT) messages. A separate find-me mode supports relative bearing-and-distance targeting for search teams. The graph follows documented calls and references; some module behavior is unsampled, so uncertain connections are omitted.
