About the Data Explorer
The California Wildfire Data Explorer (known as the “Data Explorer”) provides access to statewide maps of wildfire hazard and related information on surface fuels, fuel treatment locations, and historical fire occurrence. Additionally, multiple reference layers provide users with information on administrative boundaries, jurisdictional management, wildfire protection and suppression responsibility boundaries, and many more. The Data Explorer provides users with a consolidated experience for exploring wildfire issues across the state.
The Data Explorer information themes include wildfire hazard, demographic / socioeconomic, historical fie perimeters, political reference and administrative boundaries, watershed boundaries, wildfire response information, fuel treatment boundaries, and much more.
The Types of Data
Historical Fire Information
A comprehensive archive of historical fire information for California is maintained by the Fire and Resource Assessment Program (FRAP). These datasets can be explored in the Data Explorer alongside wildfire hazard maps and fuel treatment boundaries, or can be accessed through the Map Viewer, downloaded for use in GIS software, or viewed as a downloadable PDF map. More information on historical fire perimeters and many additional datasets can be accessed from the FRAP GIS Mapping and Data Analytics page.
Contemporary Wildfire Hazard and Risk
Statewide maps of wildfire hazard and risk provide the baseline information needed to support wildfire planning and mitigation efforts across the state. Land managers, local community groups, and private landowners alike require contemporary indices of wildfire hazard – consistently calculated and mapped across the state. The Data Explorer provides contemporary estimates of wildfire likelihood and intensity (flame-length), indices of wildfire damage including ember load, and measures of wildfire suppression challenges. Data are updated on a near-annual basis or as source data become available.
Regional Planning
The Data Explorer provides community and regional planning groups with access to needed data for focusing wildfire hazard mitigation and prevention efforts within planning areas, to assist with project prioritization, and align priorities among stakeholders through common data and visualizations. Data Explorer hazard layers are consistent with those curated as part of the Regional Resource Kits and proposed as part of the Core Reporting Metrics currently in development to assess and monitor progress toward resiliency in fire-prone landscapes.
