What is FARSITE?

• is a fire growth simulation model. It uses
  spatial information on topography and fuels along
  with weather and wind files.
• incorporates the existing models for surface
  fire, crown fire, spotting, post-frontal
  combustion, and fire acceleration into a
  2-dimensional fire growth model.
• runs under Microsoft Windows operating systems
  (Windows 98, me, NT, 2000, and XP) and features a
  graphical interface.
• users must have the support of a geographic
  information system (GIS) to use FARSITE because
  it requires spatial landscape information to run.

What does FARSITE do?

• Computes wildfire growth and behavior through
  time under heterogeneous conditions of terrain,
  fuels, and weather.
• Uses existing fire behavior models for surface
  and crown fires, post-frontal combustion, and
  fuel moisture.
• It is a deterministic model, meaning that you
  can relate simulation results directly to your
  inputs.
• Produces outputs that are compatible with PC and
  GIS.
• Can simulate air and ground suppression actions.
  
• Can be used for fire gaming, asking multiple
  "what-if" questions and comparing the results.
