What's New in FlamMap

Improvements added with August 28, 2025 version 6.2.45.0

New Polygonize command for grid themes.

Create polygons from any grid theme. Works best with categorized, not continious value, themes.

Resolution of Calculations

MTT and TOM no longer accept resolution changes, runs are done at the resolution of the landscape.

Resample Landscape Utility

To account for the change in the Resolution of Calculations, a Utilities>Resample Landscape utility is now available.This will give the user a chance to quickly create a landscape at the desired resolution.

Create Treated Landscape

A treated landscape based on a TOM run can now be saved.

Get Landscape Utility

Shapefiles can be loaded into the "Get Landscape" dialog to help with identifing bounding box coordinates.

Get Landscape also now uses the new Landfire download service.

Get Weather Utility

Since WIMS is being replaced, it has been removed from the Weather Source: drop-down list. Don't panic, all the former WIMS stations are included in the Synoptic station list. You just have to know the station name as the Synoptic list does not have the old WIMS number identifiers.

A measure tool has beed added to the "Get Weather" dialog map controls

Updated Tutorials

Updated to reflect recent FlamMap changes and utilizes current Landfire data.

Single Source Fire Models

All Fire Behavior and SpatialFOFEM binaries are now sourced from the FireBehaviorModels and spatial-fofem source tree. They are all cross platform code and the same code as is running in the Fire Modeling Services Framework.

 

Improvements added with August 30, 2024 version 6.2

Get Weather Utility

New Get Weather utility to generate Weather Stream (.WXS) files from various historic and forecast sources.

Updated online FlamMap Help File (Version 216) with new content

Surface Fire Effective Wind Speed

The Surface Fire Effective Wind Speed limit is no longer being used in FlamMap. There is currently no option to turn this on or off.

  

Improvements added with November 14, 2023 version 6.2

Updated online FlamMap Help File (Version 215) with new content   

Get Landscape Tool

The Tool will now zoom to area on the map with a visible bounding box after entering valid coordinates or after loading an existing extent from the available GetLandscape History.

Updated Contouring Routine

A new Contouring algorithm for contouring raster based output implemented. Generated contours can be as lines or polygons.

Fuel Moisture Files (.FMS)

Set allowable ranges for dead and live fuel moisture values in the fuel moisture files (.FMS) files and bounds/data range checks when using the Validate Contents tool.

Weather Stream Files (.WXS)

Set allowable ranges for weather parameters for both English and Metric equal to current ranges in the new FW21 file formats.

 

Improvements added with June 15, 2023 version 6.2

1000 Hour Fuel added to Initial Fuel Moisture File (.FMS)

1000 Hour time lag fuels have been added to the Initial Fuel Moisture File (.FMS). While not used for fire behavior runs, accurate 1000 Hour time lag fuel initialization is important when using dead fuel moisture conditioning outputs with SpatialFOFEM.

WindNinja Code Updated

FlamMap's implementation of WindNinja's Conservation of Mass Solver using a domain-averaged input wind speed and direction has been updated to that currently in the stand alone WindNinja software.

 

Improvements added with version 6.2

SpatialFOFEM

A subset of the outputs for the First Order Fire Effects Model (FOFEM) is now available. The outputs cover Fuel Consumption, Emissions, and Carbon calculations.

Get Landscape Tool

Within the United States, pre-made landscapes in a GeoTIFF (.TIF) format file can be downloaded from landfire.gov using the Landscape > Get Landscape command. This landscape is composed of all eight themes used for FlamMap and Farsite as well as an optional FCCS theme for SpatialFOFEM runs. It uses a custom local Albers projection that keeps the landscape north orientated.

Save Raster Outputs as Single GeoTIFF

Raster outputs for a FlamMap, FARSITE, or SpatialFOFEM run can now all be saved in one multi-band GeoTIFF file with the Raster Outputs to GeoTIFF shortcut command.

 

Improvements added with April 15, 2021 version 6.1

Measure Tool

 Users can draw lines and polygons on a landscape and calculate lengths and areas.

Additional support for metric units

New options for displaying and exporting outputs in metric units.

Additional support for raster formats

Additional GeoTiff support for importing/exporting raster files. Export of raster files (both ASCII Grid and GeoTIFF) now include a .AUX.XML file containing theme metadata.

 

Improvements added with version 6.1

Weather (.WTR) and Wind (.WND) files no longer supported

Only hourly Weather Stream (.WXS) Files can now be used to load weather data in a FlamMap run or Farsite Simulation.

When loading legacy projects or archives with Weather (.WTR) and Wind (.WND) files users are asked if they would like to have a new Weather Stream (.WXS) created based on the deprecated file types. Additionally there is a new Utilities > WTR and WND to WXS command to convert Weather (.WTR) and Wind (.WND) files to the Weather Stream (.WXS) File format.

New tools to edit and graph weather

 A reworked Weather Stream Editor,

GeoTIFFs now supported when generating landscapes

Single band GeoTIFF (.TIF) Files can now be used for generating a new landscape. Regardless of the format of the source themes (GeoTIFF or ASCII Grid) the resulting landscape can be saved in either GeoTIFF (.TIF) or Landscape (.LCP) file format.

Class units for aspect and canopy cover themes is no longer supported when generating a landscape, only degrees and percent respectively.

 

FlamMap version 6.0 incorporates several new tools and features.

Farsite

The Farsite fire growth simulator has been added. This adaptation of Farsite works a bit differently and not all outputs or features from FARSITE v4.1 are implemented. Improvements to the spotting model have been made to increase performance and the WindNinja conservation of mass solver is now an option.

Landscape Editor

FlamMap now includes a feature to easily edit all of the landscape themes in an existing Landscape (.LCP) or GeoTIFF (.TIF) format file.

Automatic Reprojection

FlamMap will automatically transform and reproject auxiliary themes (both grid and vector) to match the landscape projection as long as the landscape and auxiliary theme have the required projection information. However, FlamMap best practices include: having all geographic data in the same datum/projection, utilizing datum/projection information for landscapes and auxiliary themes, and using local rectangular projections such as, UTM and state Albers.

FlamMap expects all provided projection information to be configured in the Open Geospatial Consortium-Well Known Text (OGC WKT) format.

Import Runs

Runs can be added to a FlamMap project with either a previously saved Run Log or a WFDSS or IFTDSS inputs file.

Creating Shapefiles

Drawing vectors and saving as shapefiles has been improved to eliminate the confusion of creating different shapefile types. Unfortunately this removes the beloved driptorch toolbar button form the toolbar.
