AdvTAK is an offline-first tactical GIS for field teams, search & rescue, and emergency response — offline vector maps, 3D terrain, serverless team sync, and mission reporting. No accounts. No cloud. No signal required.
Every capability is engineered to keep working after the last bar of signal disappears.
Download whole regions, import PMTiles/MBTiles archives, and let the smart cache keep every tile you've seen. Missing tiles fall back gracefully — the map never goes blank.
Real 3D terrain, hillshade, slope-angle shading computed on-device, and elevation profiles along any route — for planning lines you can actually move on.
Live positions, shared markers and routes, and team chat with voice — over P2P, LAN hub, or Reticulum mesh. Join a session with a QR code. Leave no trace in any cloud.
SITREP reports, CASEVAC casualty reports, PACE communication plans, mission task checklists, and supply tracking with days-of-supply estimates — all local-first.
GPS with compass heading, breadcrumb tracks, bearing navigation to any target, magnetic declination, and coordinates in DD, DMS, DDM, UTM, and MGRS.
Everything stays on your device. Move it with GeoJSON, KML, and GPX — or one encrypted backup file: AES-256, your password, no recovery server because there is no server.
USGS, Esri, OpenTopoMap, OpenStreetMap, and key-free vector styles with fonts and icons bundled for cold-start offline rendering. Every base overzooms to z22, plus a 1,345-source imagery catalog.
Operational periods, clue markers, sector assignments, and live team positions — synced over the LAN when the grid is down.
Topo detail, slope shading, public-land boundaries, and breadcrumb tracks for country that has never seen a cell tower.
SITREPs, CASEVAC, PACE plans, and shared mission maps when infrastructure is the first casualty.
One codebase, two ways to carry it. Install once — it works offline from then on.
Native app for Android 7.0+. Background region downloads, native GPS and compass, file-system map imports.
