The Fire Environment Mapping System (FEMS) is a new wildland fire IT application which will support wildland fire preparedness and decision-making with better access to fire environment datasets and online analysis tools. FEMS will support a core principle of the Cohesive Strategy, that all jurisdictions participate in making and implementing risk-based wildland fire management decisions using the best available science. FEMS will be dynamic in design to evolve as new science addresses unmet fire weather and fire danger business needs. The platform should respond to and incubate new ideas from research to operations.
