The purpose of the Texas Wildfire Hazard Assessment (TxWRAP) is to provide foundational information about wildfire hazard across all land ownership in the state of Texas. Such information supports fuel management planning decisions, as well as revisions to land and resource management plans. A wildfire hazard assessment is a quantitative analysis of potential impacts by wildfire.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This spatial dataset was produced with the Wildfire Exposure Simulation Tool (WildEST), a cloud-based geospatial fire behavior characteristic simulation system. WildEST performs multiple deterministic simulations under a range of weather types (wind speed, wind direction, fuel moisture content) and weights those results based on weather type probabilities (WTP).</SPAN></P><P><SPAN STYLE="font-weight:bold;">This dataset is a raster representing Suppression Difficulty Index (SDI) across the project area. 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.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Additional information on the SDI can be found in the following references:</SPAN></P><P><SPAN STYLE="font-weight:bold;">Rodriguez y Silva, F.; O'Connor, C.D.; Thompson, M.P.; Molina, J.R.; Calkin, D.E. 2020.
