Service Description: Wildfire Suppression Difficulty Index is a quantitative rating of relative difficulty in performing fire control work. SDI factors in topography, fuels, expected fire behavior under severe fire weather conditions, firefighter line production rates in various fuel types, and accessibility (distance from roads/trails) to assess relative suppression difficulty. The SDI can be used to help inform strategic and tactical fire management decisions. Fire behavior inputs were modeled in WildEST at 30m resolution, incorporating both temporal frequencies of weather types and the influence of high-spread conditions as well. Please reference the CAL report for more detailed information. Raster resolution is 30m. Data finalized 1/31/2021.
