Search and Rescue Application

검색 및 구조 앱

SARApp supports Search and Rescue operations by leveraging a phone's GPS receiver to document where a searcher has looked. This information is transmitted via 3G/4G or Wi-Fi to the web-based SARApp server, which can be used for real-time situational awareness and calculation of Probability of Detection at the Incident Command Post. The SARApp client supports volunteering electronically for a search, viewing the assigned search sector, and displaying the user’s tracks as well as those of other SARApp users. Searchers can also use the phone to take geo- and time-tagged photo and video evidence that can be transmitted back to the server for map-based display. SARApp works over land, in the air, and on water – wherever GPS signals can be received. If a phone lacks 3G/4G connectivity, the app will store track and evidence data until it is within range to transmit.

In addition to field search activities, SARApp can be used as a general real-time situational awareness or field intelligence collection tool. For example, personnel responsible for documenting storm damage, fire boundaries, road closures, the extent of flooding, or evacuated houses could use SARApp to send photos and video back to the Server for viewing on a map.
