Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>FROM ORIGINAL DATASET:</SPAN></P><P><SPAN>In its original formulation for use in Spain, SDI included aerial resource use, however for development and application in the United States we removed the aerial resource component due to a lack of consistent data. We note this distinction of “terrestrial only” calculations with the inclusion of “t” in the acronym. SDIt 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 effort. For this dataset severe fire behavior is modeled with 15 mph up-slope winds and fully cured fuels. This SDI dataset has a continuous value distribution from 0 - 1, anything above 1 is considered HIGH.</SPAN></P></DIV></DIV></DIV>
