Meret – Offline maps and GPS logging for field teams

Early. The project skeleton, core model, database and location engine are done; tracking, maps and forms are next.

The problem

Field teams in low-connectivity regions run on paper forms, separate GPS units and map apps that degrade off-network, and supervisors cannot see where a team went or what it recorded.

The approach

An Android app built to work all day in aeroplane mode: offline vector base maps from a local tile pack, and GPS tracks that survive screen-off and aggressive task killers, with raw points preserved.

Results

  • Phases 1–4 of the build plan are done: skeleton, core model, database, location engine.

What broke and what I learned

  • Phase 0 tooling for the offline tile pack is done, but a real Ethiopia pack has not been built yet, and acceptance criteria that need a physical phone are not claimed by CI.
