MTBS Workshop (November 30, 2009): MTBS hosted a one day workshop at the 4th International Fire Ecology & Management Congress in Savannah, GA. The workshop objective was to introduce participants to the concepts and principles used by MTBS to map fire severity using remote sensing. Participants learned how to access MTBS data via the project website, customize MTBS fire severity data for specific user needs, integrate and analyze these data with local GIS map layers, and how this information can support management decisions. The slide show presentations and self-paced exercises that were created to meet the objectives of the workshop will be available for download from the Tech Transfer page in the coming months.
