FOR-438 Tool Data Flow Overview
Data re-runs
FBAT (Fire Behavior Assessment Tool) FlamMap
ACT (Area Change Tool)
FRCC Mapping Tool
MRIT (Multi-scale Resource Integration Tool)

Tool Data Flow
FlamMap
  • Available from fire.org web site
  • Outputs raster maps of potential fire behavior
  • Rate of Spread (ROS)
  • Flame length (FL)
  • Crown fire activity (CFA)
  • Uses same input files as FARSITE
  • Landscape (.LCP)
  • Initial Fuel Moistures (.FMS)

Data output
FBAT (Fire Behavior Assessment Tool)

Damn Wendel, why do we keep crashing the Area
Change interface? Hhhmmmm..Must be an
inverted command line code, causing a data stream
interruption.
5
Objectives
  • Provide cursory overview of the FlamMap model
  • Learn the minimum inputs required for making
    FlamMap runs
  • Understand layers to be synthesized in Fire
    Behavior Assessment Tool (FBAT)
  • Complete exercise, and discuss FlamMap outputs
    and uses

6
Why add fuel planning skills?
  • Girls only like boys with great skills.
    Nunchuck skills, bowhunting skills.
  • Instead of I caught you a very delicious
    bass..
  • I integrated WUI, FRCC, and absolute fire
    behavior in the MRIT. Gosh.

7
What is FlamMap?
  • Fire Behavior Model that creates raster maps of
  • Potential fire behavior characteristics
  • Rate-of-spread
  • Flame length
  • Crown fire activity
  • Fireline intensity
  • Horizontal spread rate
  • Fuel Conditioning (advanced options)
  • Dead fuel moisture
  • Mid-flame windspeeds
  • Solar irradiance

8
Basic Steps to run FlamMap
  • Acquire a landscape file (.lcp) and fuel moisture
    file (.fms) for area of interest
  • Provide required inputs describing environmental
    conditions
  • Select the desired output layers
  • Launch FlamMap and interpret results

9
How does it work?
  • Pixel based each pixel burns independently
    fire behavior is not influenced by neighboring
    pixels
  • Uses ASCII grids
  • NOT temporal - uses constant weather and fuel
    moisture parameters
  • Partially spatial does not map fire perimeters
    or incremental growth
  • Uses same spatial and tabular data as FARSITE
    (.lcp and .fms files)

10
Spatial Input DataASCII grids of
  • Topographic data
  • Elevation (DEM)
  • Slope
  • Aspect
  • Fuels data
  • Fire behavior fuel model (FBFM 13 or 40)
  • Stand height
  • Canopy base height
  • Canopy bulk density
  • Canopy cover

11
Model ParametersInput by User
  • Fuel moisture file (.fms), by fuel model
  • Dead 1-hr, 10-hr, 100-hr,
  • Live herbaceous, woody
  • Canopy foliar moisture (75 125)
  • 20-ft wind speed (above crown)
  • Wind direction (directly upslope or from azimuth)

12
Output Data
  • Rate of Spread
  • Flame Length
  • Crown Fire Activity (each pixel classified as
    unburned, surface, passive crown, active crown)

13
What is a landscape file?
  • A grid containing rasterized spatial inputs of
    topographic and fuels information for a landscape
    of interest
  • Potential problem LANDFIRE ArcGRIDS
  • Solution Convert ArcGrids to ASCII in
    ArcToolbox
  • LCP files downloadable from National Map website
  • Build LCP file in FlamMap from ASCII grids

14
Preparing Input Data
  • Converting ArcGRIDs to ASCII format

15
At National Map website, under download and
FARSITE tabs, select landscape file
16
Getting Startedbuilding the landscape (lcp) file
ASCII file inputs
17
Selecting Input Parameters
Weather/Fuels Parameters
18
Selecting Fuel Moisture Wind Parameters
  • Dependent upon your analysis objectives
  • Worst case potential wildland fire behavior?
  • Comparing outcomes of multiple burning
    prescriptions?

19
Building the Fuel Moisture File
FM 1-hr 10-hr 100-hr LH LW
  • Text file
  • Acquire from Fuels
  • Specialist, NFDRS
  • Potential Editors
  • Note Pad
  • Word Pad

Exercise Review
  • When is flame length the overriding concern?
  • When is rate of spread the most important
    consideration?
  • Does one layer have more relevance to
  • Firefighter safety?
  • CWPP or WUI planning?
  • Selective thinning followed by burning?
  • Fire effects modeling?

33
Exercise Review
  • What are obvious limitations to FlamMap?
  • Would it be helpful to have the outputs
    classified into key thresholds (e.g., Hauling
    chart, nomograms, etc.)?

20 mph windspeed, general wind
50 mph windspeed, cold front passage
