From the InciWeb about page:
InciWeb is an interagency wildland fire incident information management system. The system was developed with two primary missions: The first was to provide a standardized reporting tool for the Public Affairs community during the course of wildland fire incidents. The second was to provide the public a single source of information related to active wildland fire information.
A number of supporting systems automate the delivery of incident information to remote sources. This ensures that the information on active wildland fire is consistent, and the delivery is timely.
