TacMap: Offline GPS Field Maps

TacMap is an offline map for the field: unlock once, with no subscription. No TacMap account, ads or behavioural analytics. Built for hiking, hunting, overlanding, search and rescue, surveying and MGRS navigation. MAPS WITHOUT A CONNECTION • Import PDF, GeoPDF and MBTiles maps and keep several to switch between. • GeoPDFs are placed in the sheet's own projection and datum, so the MGRS grid lines up with the printed grid. • Calibrate a plain PDF, including a scan or photo of a paper map saved as PDF, from three or more grid references (MGRS, UTM or latitude/longitude) and see how accurate each one is. • Maps stay sharp as you zoom in, and can be saved as offline tiles. • Use imported maps offline, without country restrictions. • Online basemaps, terrain elevation and weather are optional and require a connection. NAVIGATE AND PLAN • Read your position in MGRS, UTM or latitude/longitude. • Keep the map North Up or rotate it with your heading. • Measure distances, areas and bearings in degrees or NATO mils. • Add waypoints, draw lines and areas, and organise them into layers. • Use search-and-rescue, points-of-interest, airsoft and NATO APP-6 symbols. • Record your route and export GPX tracks. • See the elevation profile and line of sight along any line. Uses online lookups. • Red night mode protects your night vision. • Offline sun and moon times, and range rings around any symbol. WORK TOGETHER • Share drawings and symbols between iOS and Android with end-to-end encrypted Unit Sync. • Optionally share your callsign, position and heading with your unit. • Send encrypted text or reports to the room or a selected live unit with TacMap Chat. • Screen-off location sharing has a separate switch. Updates depend on the operating system and connection. • The relay cannot decrypt mission content, but sees admission, routing, session and control data, Chat recipients, IP addresses, timing and data size. “Routed” is not delivery or read proof; member status is relay-reported. YOUR DATA, YOUR TOOLS • Import and export GeoJSON, KML and KMZ, for QGIS, Google Earth and ATAK. • Export mission objects together; recorded tracks remain separate GPX files. • Mission data is encrypted in app-private storage. Imported maps remain in private, device-protected storage. • Online basemaps and lookups are off at first launch and can be enabled independently. While enabled, providers receive your IP address and requested map area, search query or coordinates. Coordinate and mission search stays on-device. • Optional PIN or biometric app lock. For Android phones and tablets. ENGLISH AND GERMAN Choose English, German or Device language in Settings. Your own names, notes and messages remain unchanged.
