Run the operation
from a browser.

Five things
baseTAK does well.

OUTCOME 01

Put a real TAK client on every laptop in the room

baseTAK is a full TAK map in a browser — no app to install, no per-device licensing, no tablet requirement. Anyone on the LAN with Chrome, Firefox, or Safari is a participant.

• Native COT creation — markers, routes, polygons, rectangles, ellipses, circles, range rings, bullseyes, bearing-distance lines.
• Telestrations and freehand drawings — sketch on the map and broadcast to every TAK client.
• Editing parity — rename, recolor, move, re-broadcast any marker with original creator attribution preserved.
• 3D terrain with EGM96 geoid elevation accuracy — meters HAE-to-MSL, not approximated.
• KML / GPX / KMZ import preserving symbology, names, and geometry.

OUTCOME 02

Operate at the speed of the incident

WinTAK takes four or more clicks to drop a marker and broadcast it. In a fast-moving incident, that's a tax on every decision. baseTAK is built around the operator: turn on broadcast-by-default and every new marker, drawing, icon, or shape is on the wire the moment you place it. Two clicks. Done.

• Broadcast-by-default mode — every new entity is on the wire immediately. No "send" button, no "are you sure" dialog.
• Curated icon set — pruned to what operators actually use in the field. Faster selection, lower cognitive load.
• Working panes designed around the map — UI chrome is collapsible and minimal so the map gets the screen.
• Keyboard shortcuts for every common action — drop, draw, send chat without leaving the keys.

OUTCOME 03

Keep every map in sync — even when the network isn't

baseTAK is designed for the imperfect networks operations actually run on — Wi-Fi APs that drop packets, mesh hops that flake out, devices that come and go. Markers don't get lost; every TAK client on the network stays in sync without an operator having to chase anyone down.

• 3-burst initial broadcast — every new marker, drawing, or shape is emitted three times at 30-second intervals when it's created. A client that missed the first send because of a flaky AP gets caught up on the next one. No operator action required.
• Per-COT-type re-broadcast cadence, admin-configurable — after the initial burst, each COT type has its own admin-set cadence for ongoing re-broadcast. High-value items (evac zones, hot zones, critical contacts) re-broadcast often; static infrastructure markers re-broadcast rarely. The picture stays current without flooding the wire.
• Take ownership of other users' COTs (in development) — a designated user can take ownership of any marker on the wire, including ones placed by other operators, and baseTAK keeps re-broadcasting it from then on. No more orphaned markers when the operator who placed them goes off-net.
• Per-field echo filtering — when the same COT comes back from a different bridge (APRS, mesh), only genuine field changes update the record.
• SQLite-backed persistence — the picture survives a restart, a power cycle, a swap of the laptop, a swap of the IC.

OUTCOME 04

Stop pre-loading maps on every tablet

baseTAK ships with a standard tileserver built in. Every TAK client on your network — baseTAK browsers, ATAK, WinTAK, iTAK — pulls the same maps from one source. So does anything else that speaks the standard tileserver format.

• One source of maps for every TAK client — baseTAK, ATAK, WinTAK, and iTAK all point at your baseTAK and pull from there. One map stack to maintain, not four.
• Direct EUD tile download over the network — when a tablet is connected, it downloads tiles directly from baseTAK on the fly. No HQ provisioning of every device, no sideload, no SD-card preflight.
• Standard tileserver format — anything that speaks XYZ / TMS / MBTiles can consume the same maps. The basemap stack you load is reusable across any compatible app, not just TAK clients.
• Multi-source basemaps — aerial imagery, USGS topo, OpenStreetMap, FEMA hazard layers, custom overlays — any standard tile format works.
• And it extends to the field. baseTAK Lite — the same tileserver on a netTAK field node — serves maps to every TAK device at a forward site without backhaul.

OUTCOME 05

Drop any xTAK product on the LAN — it just shows up

Drop any other xTAK product on the same LAN and it just shows up. Every product speaks the same TAK protocol on the same network.

• digiTAK feeds APRS stations and bridged sites onto your map.
• loraTAK feeds Meshtastic LoRa node positions and chat.
• sdrTAK feeds decoded aircraft (1090 ES, UAT 978) and ships (AIS).
• chatTAK browser users appear as their own first-class TAK endpoints.
• netTAK extends the LAN over a self-managing wireless mesh — drop an appliance at each site, they auto-form.

What's in the box.

baseTAK ships every primitive an operator needs to run a real TAK picture from a browser — full CoT origination, drawing, chat, file transfer, and offline tiles. Multi-user, multi-device, self-hosted, no app install.

• Multi-user enrollment — every browser session is a distinct TAK identity with team color, role, and live presence.
• Full CoT marker origination — friendly, neutral, hostile, custom iconsets, full MIL-STD-2525C symbology.
• Filter the map by icon type — show only the markers you care about. Paired with digiTAK, the filter is APRS-symbol-aware (weather stations only, mobile trackers only, digipeaters only). Paired with sdrTAK, you filter aircraft by emitter category (helo, heavy, light, glider, military) and ships by AIS type. One control, multi-source decluttering.
• Drawing primitives — freehand telestration, polygons, rectangles, range rings, bullseyes, lines, ellipses, circles.
• Route planning with elevation profile and magnetic-declination-corrected bearings (WMM2020).
• Address + business search — find any location by typing an address, intersection, or business name. Backed by open-source geocoding data — no Google API key, no per-query fees, no third-party tracking.
• Track history — record and play back any unit's movement; convert any track to a route.
• Lock-on · Pointer HUD · Resection — operator-grade nav primitives, not just a map viewer.
• Geofences with entry/exit + cross-shape alerts.
• Emergency lifecycle — alert, "ring the bell," lockdown; full b-a-o-tbl + b-a-o-pan compliance.
• 3D terrain with EGM96-correct altitude (HAE, not approximated MSL).
• KML / GPX / KMZ / TAK Data Package import + export, with symbology preserved.
• Native GeoChat — broadcast, team, DM, custom groups, attachments, read receipts.
• Built-in TAK file server — send and receive files up to 50 MB to any WinTAK/ATAK/iTAK client. Emits the standard b-f-t-r fileshare CoT, validates SHA-256, exposes an HTTPS endpoint at /api/attachments/<id>/zip, and tracks every attachment in SQLite as an auditable trail. No TAK Server required.
• Built-in tileserver — serves very detailed maps to every TAK client on the network (baseTAK, ATAK, WinTAK, iTAK) and to any other app that speaks the standard tileserver format. EUDs download tiles directly when connected over the network.
• SQLite persistence — the picture survives restart, power cycle, hardware swap. Your data stays on your hardware.
