The Indiana Mapping Project is a Geographical Information System (GIS) environmental emergency response tool that brings public (Federal, State and local) entities and private sector emergency responders together for spill response and pre-planning.

During an emergency response, Federal and State On-Scene Coordinators (OSCs) may use the program to gain situational awareness of downstream/downwind vulnerabilities, as well as upstream/upwind potential responsible parties and much more. For contingency planning, the project can introduce facilities to the communities which may be impacted during a hazardous materials and/or petroleum releases.

The program can also be used during exercises of facility response plans by providing participants access to response layers such as: endangered/protected species and habitats; sanitary and storm sewer systems; facility discharge and permit discharge points; water supplies; other pollution sources (facilities, oil wells, pipelines, rail lines, etc.); and vulnerable populations (schools, nursing homes, daycare facilities, hospitals, etc.).
