User Guides


Modifying LANDFIRE Geospatial Data for Local Applications provides an easy-to-understand introduction to each of the LANDFIRE products, explains where and how to look for common problems with the data and offers guidance on how to complete common modification tasks. This guide is an excellent resource for anyone working with LANDFIRE data, but will be especially helpful to users who need to refine the data for local application.

Reviewing & Modifying LANDFIRE Spatial Products - The purpose of this guide is to provide an introduction to concepts, processes and tools that will allow users to review LANDFIRE spatial products and alter those products as needed for local application.

Guidebook on LANDFIRE fuels data acquisition, critique, modification, maintenance, and model calibration provides guidance on ACE as well as on assembling a geospatial fuels team, model calibration, and maintaining geospatial data and documentation.   

Reviewing & Modifying LANDFIRE Vegetation Dynamics Models guide provides an introduction to concepts, processes and tools that will allow users to review the vegetation models and accompanying descriptions and then alter them as needed for local application.   

Adapting LANDFIRE Vegetation Dynamics Models - As you model, you may wonder if it would ever be possible to model multiple ecosystems at once, even having areas transition from one ecosystem to another (e.g., ponderosa pine stands replaced by pinyon-juniper) as may happen with climate change.  The answer is now a definite “YES” in VDDT's successor ST-Sim. However, the concepts and exercises in this manual will be a great introduction to modeling and will prepare you for future adventures in Path.

BpS Model Tutorials

1.     If you are new to state-and-transition modeling or to ST-Sim we recommend that you begin with the tutorial Understanding a LANDFIRE Model in St-Sim.  This tutorial explains the basic components of a model in ST-Sim. A LANDFIRE model is incomplete without its description document -- learn How to Link the BpS Model and Description.

2.     The next step is to Find a Specific BpS of interest in the LANDFIRE ST-Sim library.  Not sure what BpS code you are looking for? Use our BpS Model Search spreadsheet. If you would like help understanding the BpS codes, read about Deciphering the BpS Code.

3.     If you plan to experiment with a model, you will want to Copy and Paste a Model into its own library. Then, learn How to Edit a Modelincluding adding or removing disturbances, changing probabilities and adding or removing classes.

4.     Finally, you can Run the Model and Graph the Results. If your analysis involves models and spatial data, learn How to Link the Model with the Spatial Data. 


Spatial Data Tutorials

Updating LANDFIRE Fuels Data For Recent Wildfires - (Document) This tutorial is intended to outline a process for updating fuels geospatial data after wildfire. LANDFIRE delivers updated products every few years, but users sometimes need to update the products more frequently due to landscape change. The example documented here shows the process used for updating LANDFIRE fire behavior fuel model (Scott and Burgan) and the associated canopy fuel rasters (forest canopy cover, forest canopy height, forest crown bulk density, forest canopy base height) for recent wildfires on the Sawtooth National Forest in Idaho

How to Map Succession Classes (S-Classes) - LANDFIRE maps the current succession classes, or the ontogenetic stages, of Biophysical Settings (BpS). This succession class (S-class) spatial dataset allows land managers and other interested data users to assess current percentages of each S-class for large areas. For many users, the S-class product may be sufficient as delivered, but in other cases, users may choose to modify it or create their own S-class grid. This guide describes the four-part process to adapt LANDFIRE products to specific landscapes.

Overlay Grids Using the "Combine" Function (5:13 min. video) - This video demonstrates how to use the “combine” function in ArcGIS. Combining grids is useful for comparing datasets and a variety of other analyses.     

Calculate the Area for Each Type Mapped in a Grid (4:50 min. video)  - This video demonstrates how to calculate the area mapped for each type in a grid in ArcGIS. Calculating the area can be part of a data review or analysis process.

Editing Raster Attributes (5:43 min. video)  - This video demonstrates how to edit a grid attribute table in ArcGIS. Editing grid attribute tables is one way to modify data for local use.

Making a New Raster from an Existing Raster Attribute  (5:48 min. video)  - This video demonstrates how to make a new raster from a field in an existing raster in ArcGIS. Once an existing raster has been edited, it is often helpful to make a new raster for further analysis or display purposes.  


  Downloading Data Tutorials

LANDFIRE Data Access Tool (LFDAT) - DEMO (14:50 min. video) - This live demonstration covers how to download, install and use the LANDFIRE data access tool to obtain LANDFIRE data.      

LANDFIRE Data Distribution Site - DEMO (14:26 min. video) - This live demonstration covers how to view and download data from the LANDFIRE Data Distribution Site. 


 Vegetation Condition Class Tutorials

Introduction to Analyzing Ecosystem Health -- This tutorial explains two ways to explore ecosystem health or Vegetation Condition Class (VCC). VCC compares current conditions to reference conditions in terms of vegetation structure and composition.

Review and Modify FRCC Mapping Tool Reference Conditions - This tutorial provides a step-by-step guide on how to modify the FRCC Mapping Tool reference conditions table.

Convert a LANDFIRE Refresh BpS Grid to a BpS Group Grid -- The LANDFIRE Refresh 2001 and 2008 BpS grid requires pre-processing before use in the FRCC Mapping Tool if it is to be used with the LANDFIRE Refresh succession class grid.

FRCC Mapping Tool Video Series -- A series of video resources to instruct users on the Fire Regime Condition Class Mapping Tool. Topic areas include: Getting Started, Pre-processing Mapping Tool Inputs, Running  the FRCC Mapping Tool, Interpreting Data and Results, Trouble-shooting & FAQ.

Running the FRCC Mapping Tool with LANDFIRE Data, Part 1 (3:53 min. video) -  Part 1 of this  2-part series, demonstrates running the FRCC Mapping Tool with LANDFIRE BpS and S-class grids to calculate and map Vegetation Departure and Vegetation Condition Class. 

Running the FRCC Mapping Tool with LANDFIRE Data, Part 2 (4:18 min. video).This video is part 2 of a 2-part series. It demonstrates reviewing the Vegetation Condition Class and Vegetation Departure outputs from the FRCC Mapping Tool.
