Assessing Hazard and Risk in the Interface: Cautions and Confessions from a Statewide Mapping Effort

Presenter: Dave Sapsis, CALFIRE Fire and Resource Assessment Program

Description: This webinar will focus on elements required for statewide or regional scale mapping efforts designed to describe and classify ignition exposure to buildings that are associated with wildland (vegetation) fires, and their potential spread into urbanized areas. In addition to covering input data and spatial processing rules, the talk will also address methods of local review and validation, as well fundamental challenges of modeling key mechanisms such as ember production and transport, and the influence of data scale on map precision and accuracy. Finally, the talk will address ongoing concerns over long‐term updates and maintenance.
