Cal Fire (California Department of Forestry and Fire Protection)
Definition
California's state fire agency, which has integrated drone aerial survey and multispectral imaging into major wildfire investigations since 2018. Operational use in the 2018 Camp Fire investigation contributed spatial data characterising the relationship between the ignition area and the PG&E transmission-line corridor.
