Historical Disturbance

LANDFIRE (LF) disturbance products are developed to provide temporal and spatial information related to landscape change. Historical Disturbance (HDist) is developed from the base LF Disturbance products (and attribute code system) to represent the 'history of disturbance' for a 10-year span. Each year's disturbance scenarios are checked against time relevant LF vegetation to check for logical inconsistencies. Errant disturbance codes are flagged and updated to a discard code with the remaining disturbance codes cross walked to Fuel Disturbance (FDist) codes. HDist development involves a comprehensive review of fuel and disturbance attributes.

Starting with LF Remap, HDist replaces Vegetation Disturbance from previous LF versions incorporating pre-disturbance vegetation logic (based on disturbance year and vegetation type).

LF uses HDist in the development of several subsequent layers, including the FDist product.
