The Tactical Assault Kit (TAK) is a tool used by the Department of Defense (DoD) for mission planning, geospatial, Full Motion Video (FMV), and system administration. It reduces the operational footprint from a tactical laptop to a commercial mobile device. The geospatial engine and communications component support DoD and commercial sector standards. The Software Development Kit enables any partner to develop mission-specific capability or contribute to the advancement of the baseline. Data can be pre-loaded into ATAK or downloaded from the network when available.<br/><br/>ATAK-CIV is the civil use version of ATAK. It includes online and offline mapping, collaborative mapping, location marking, sharing, history, chat, file sharing, photo sharing, video sharing, streaming, navigation, elevation tools, heat maps, computed contour maps, viewsheds, routes, hashtags, sticky tags, range, bearing, and other measurement tools, network-aware geofences with triggers, "Bloodhound" destination tracking, team emergency beacons, customizable toolbar, radio controls and integration, photo to map capability, casualty evacuation tool, icon support for a wide variety of First Responder missions, 3D perspective, and ability to display 3D geospatial models.
