15. Oct-03Learning to Use FOFEM 5: Advanced Lesson FOFEM 5 batch mode Some users need to make hundreds or even thousands of FOFEM runs –E.g., to simulate potential fire effects across a landscape or under a range of fuel moisture conditions A batch mode of FOFEM 5 is under development Check the website for updates if you need this feature

16. Oct-03Learning to Use FOFEM 5: Advanced Lesson Linking FOFEM 5 to a GIS A GIS analyst can simulate the spatial distribution of fire effects by linking FOFEM 5 to a GIS The landscape is first divided into homogeneous units, then model inputs are set for each unit. Then the analyst simulates fire effects using a FOFEM batch run Finally, the FOFEM batch run output attributes are linked back to the original units, allowing the spatial display of effects such as probability of tree mortality, smoke production, fuel consumption, etc.

17. Oct-03Learning to Use FOFEM 5: Advanced Lesson Advanced Lesson: Conclusion The soil heating and Burnup fuel consumption models can be run from a file, allowing greater control of model input parameters. FOFEM 5 can be used in batch mode for analysis in a statistical program or for use in a GIS; check fire.org for availability of this feature.
