Fire Return Interval Departure (Frid) - Time Since Last Fire
Time Since Last Fire (TSLF), from the Fire Return Interval Departure (FRID) map, provides information (in years) to indicate the length of time since an area last burned. -
Fire Ignition Probability Lightning Cause
These rasters depict the predicted human- and lightning-caused ignition probability for the state of California. Ignition is regulated by complex interactions among climate,... -
Ignition Cause -1992-2020 - All Causes
The original point layer (WildfireOccurrence_CA_1992_2020.shp ) contains a spatial database of wildfires that occurred in the United States from 1992 to 2020. It is the fifth... -
FIA Forest Types
Managers work with forest types for a variety of purposes and knowing the major forest type of a target location helps to assess the best suited treatment for the site. The F3... -

Lakes/Reservoirs
Water Bodies such as lake and reservoir features are represented in this layer pulled from the National Hydrography Dataset (NHD). These data were used to erase areas of lakes... -
Urban-Agriculture Land Use
This dataset covers the urban and agricultural landscape for all forms of urban and agricultural land use in California. It was created using a combination of best available... -
Building Structure Density
A raster dataset containing building footprints of California. The vintage of the footprints depends on the vintage of the underlying imagery. Bing Imagery is a composite of... -
Wildland Urban Interface (WUI)
Determine building density and vegetation cover on a pixel-by-pixel basis (Bar Masada et al., 2013). Values in the raster are defined as: 0: Not WUI, 1: Intermix WUI, 2:... -
Housing Unit Density
HUDen is a raster of housing-unit density measured in housing units per square kilometer. The HUDen raster was generated using population and housing-unit count and data from... -
Fire Severity Classification
Fire severity classification (low, moderate, high) that burned within the last 10 years (2012-2021). The difference-adjusted relativized difference normalized burn ratio (RDNBR)... -
Annual Burn Probability
Annual Burn Probability represents the likelihood of a wildfire of any intensity occurring at a given location (pixel) in a single fire season. In a complete assessment of... -
Fire Return Interval Departure (Frid) - Mean Condition Class
This metric, uses the mean percent FRID to a measure of the extent to which contemporary fires (i.e., since 1908) are burning at frequencies similar to the frequencies that... -
Fire Return Interval Departure (Frid) - Mean Percent - Since 1970
Percent FRID (PFRID) quantifies the extent in percentage to which recent fires (i.e., since 1970) are burning at frequencies similar to those that occurred prior to Euro-... -
Fire Return Interval Departure (Frid) - Current Fire Return Interval -Since 1970
The fire return interval departure (FRID) analysis quantifies the difference between current and pre-settlement fire frequencies, allowing managers to target areas at high risk... -
