This webinar presents LANDFIRE's Modeling Dynamic-Fuels with an Index System (MoD-FIS), which supports the need for fire behavior fuel model grids to predict fire behavior, during drought or seasonably dry conditions. These provisional products have been released for the Southwest and Great Basin regions, and are ready for testing and review by those who use LANDFIRE data. In this webinar, Charley Martin, LANDFIRE Fuels Team Lead, and Tobin Smail, Fire and Fuels GIS specialist, both Technical Support Services Contractors to the USGS Earth Resources Observation and Science (EROS) Center, offer a MoD-FIS primer, explain how the products can be used in these regions, and solicit users’ input and review.
