LANDFIRE Remap (LF 2.0.0)

LANDFIRE (LF) Remap is a comprehensive mapping effort that used new data to create a new base map product representing contemporary conditions. LF's second base map, LF Remap, represents circa 2016 ground conditions and is being released incrementally 2019-2020.

The first base map (LF National) product suite was developed using Landsat data circa 2001. LF National products were updated regularly to more accurately represent current conditions and account for landscape disturbances (LF 2008, 2010, 2012, and 2014). With a base map more than 15 years old, it was time to remap the landscape.

Designed to produce vegetation and fuels data that inform wildland fire and ecological decision systems, LF Remap follows the Program's consistent methodologies and processes to incorporate current satellite imagery, contemporary data sources, and the latest software and hardware technologies. The resulting LF Remap products offer significant improvements to all previous LF versions.

Advances in image compositing, tiling algorithms, plus faster computing hardware ensures LF data remains relevant. To achieve this, LF Remap leveraged the Landsat archive, lidar data, and user contributed field plot data compiled into the LF Reference Database (LFRDB), to create the new base map vegetation products.

'NEW' - LF Remap changes to fuels products in disturbed areas

A discrepancy in Time Since Disturbance (TSD) 1 (0-1 years) for surface and canopy fuels in disturbed areas has existed in previous versions of LF Update products. This issue has now been corrected. TSDs have been synchronized for surface and canopy fuels in disturbed areas. Starting with the Southwest release of LF Remap, both the Northwest and Southwest LF Remap products (and future LF Remap releases) will be delivered with a TSD factor that better represents current conditions.

LF Remap fuels products in disturbed areas will be updated to expected 2019 vegetation conditions for disturbances that have occurred between 2010 and 2016, making the fuels products "2019 capable." This improves performance of fire behavior modeling and reduces the need for local LF users to update the vegetation and fuel conditions to represent current conditions. LF Remap products will better represent active and potential wildfire behavior on the current landscape when compared to results where all the disturbed areas depict circa 2016 conditions.

All LF product categories have been refined as part of Remap:   Reference  •  Disturbance  •  Vegetation  •  Fuel  •  Fire Regimes  •  Topographic

LF Remap Schedule

LF Remap production began in 2017. Product releases by LF Geographic Areas (GeoAreas), six for CONUS, and one each for Alaska, Hawaii, and the insular areas, started with the Northwest in early 2019 and will continue incrementally through 2020.

Budget Constraints

LF experienced FY 2018 budget reductions. The Program is evaluating options which may include schedule delays, scope adjustments, and deliverable cuts. As of March 2018, no changes have been made to the current schedule. After the budget is finalized, additional information and changes will be provided.

What to Expect — LF Remap Changes

The LF team at the USGS Earth Resources Observation and Science (EROS) Center used the latest data and processing techniques to produce new vegetation, fuels, and fire regime base layers for the LF Remap product suite, representing a circa 2016 ground condition.

LF Remap changes include:

LF Remap Documentation

LANDFIRE Capable Fuels - changes to the fuels assignment process for LF Remap - a technical description of the refinement to the LF Remap products now representing "capable" fuels.

Changing the mapping approach for fuels in disturbed areas - LANDFIRE introduces "Capable" Fuel - a summary of the new mapping process, called "capable" fuels.

LF Remap - Utilization of Remotely Sensed Data to Classify Existing Vegetation Type and Structure to Support Strategic Planning and Tactical Response - characterizing vegetation type, cover, and height with Earth observation data enhances wildland fuel modeling.

LF Remap Summary Description - published in 2015 describes a summary outline on LF Remap. Information is presented in a question and answer format to address questions users may have.

Developing LF Remap by Production Unit - Products are being developed using a combination of legacy and new productions units.

Data Call Letter - request for contributing relevant data and information from multiple sources to ensure a comprehensive product.
