Quality base data is vital to incident mapping. A GISS should gather and maintain a comprehensive data set for their local area of operation and/or home unit.
Because GISS can be assigned anywhere in the country they are needed, it is impossible to always have the required base data ahead of time. Be prepared to contact local offices (city, county, state, and federal) to request their most current data. A GISS will also work with other personnel or teams (Infrared Interpreter (IRINs), Fire Behavior Analysts (FBANs), Burned Area Emergency Response (BAER) teams, and Area Command teams) to obtain, evaluate, or provide data sets as needed.
