LANDFIRE technical documentation

Abstract

Executive Summary LANDFIRE (LF) completed the LF 2016 Remap effort in 2021, the biggest revision of its product suite since its inception. This document serves to describe the processes that went into this effort and elucidate the methods for creating each LF product. Although the document focuses on the LF 2016 Remap effort, it also details the two updates that have been completed since that effort, LF 2019 Limited (released June 2021) and LF 2020 (underway at the writing of this document). The LF program is complex, requiring a team of interdisciplinary professionals to manage, produce, and maintain it. LF data production falls under six primary categories: reference, disturbance, vegetation, fuels, fire regime, and topography. Several data production units have the dual goals of producing a valuable stand-alone dataset and serving subsequent LF production needs. This document delves into the technical details of the six primary categories individually while also describing the connections to other LF products. Importantly, this LF technical documentation provides a transparent view of actual LF data layer production processes and can become a general information source for future production, production improvements, user questions, and leadership reference.
