Infrared Interpreter

IRIN decorative banner: photos depicting IRIN position. IRIN Position Description: The Infrared Interpreter (IRIN) directs infrared mapping operations when assigned.

An Infrared Interpreter (IRIN) is responsible for interpreting infrared (IR) imagery from National Infrared Operations (NIROPS) sensors to determine the heat perimeter of fires. They produce GIS-ready files, GIS layers, geo-referenced PDF maps, KMZs, and logs. The IRIN works remotely and often independently but reports to the Situation Unit Leader (SITL). If no SITL is assigned, the IRIN reports to the Plans Section Chief (PSC) for a Type 1, 2, or 3 fire. For a Type 4 fire, the IRIN reports to the Fire Management Officer (FMO) or Assistant Fire Management Officer (AFMO). The IRIN works in the Planning functional area.
