The Wildland Fire Decision Support System (WFDSS) web-based application â€¨leverages geospatial data to inform strategic decisions on wildland fires. A specialized data team, working within the Wildland Fire Management Research Development and Application group (WFM RD&A), assembles authoritative national-level data sets defining values to be protected. The use of such high-quality trusted data ensures that critical resources, infrastructure and firefighter risk exposure are considered in both the planning and implementation phases of incident management (Figure 3 and Table 1).
Since wildland fires are most expensive when they occur adjacent to populated areas, affect multiple jurisdictions, and damage private property and structures, the need for more and better data to represent homes and individual structures throughout the country has become increasingly important. An accurate accounting of the number and approximate location of structures within the planning area for an individual fire is prerequisite to sound decision-making.
Successful acquisition and management of national-level data require considerable collaboration and communication among all affected jurisdictions and across all levels of government. The best data on where people live is maintained by county government agencies in the form of cadastral, or tax parcel, data. Since there are over 3,000 county governments in the United States, the magnitude of the necessary acquisition effort led to a partnership with wildland fire management agencies and other federal, state and local governments. This partnership was established by the creation of the Federal Geographic Data Committee (FGDC) National Cadastral Sub-Committee.
Starting in 2006, this partnership has developed business cases, established necessary data standards, and outlined procedures to consolidate and use cadastral data. The cadastral sub-committee has reached out to local county assessors, planners, natural resources and GIS staffs to acquire county geospatial parcel records. From this, authoritative county data can be consolidated by trusted state data stewards to provide information needed by federal wildland fire managers for incorporation into WFDSS.
From the cadastre record, building clusters representing the general structure locations are derived. When wildfires occur, local jurisdictions can immediately see the importance of their own data in improving decision-making and assessing wildland fire risk to property and homes.
The WFM RD&A acquires nearly 40 geospatial data sets for use within WFDSS on an annual basis. Cadastral data is one example of leveraging geospatial data to provide real-time intelligence and enhance wildland fire managers’ decision-making capabilities. It is also a good example of information that did not exist in a readily usable format as little as 10 years ago.
Local land-use situations are changing rapidly with housing and infrastructure values dramatically expanding across the landscape. The ability to have and use this kind of data strongly advances decisions regarding kinds, types and numbers of firefighting response resources, tactics that will be used and where the highest priorities are.
