Hi Pedro,
Thank you for the reply and it helped me a lot. So here what I did. I
needed to create the raster file such wind speed is 230 ft/min. So I used
the following command.
r.mapcalc "new_wind_speed = 350"
Then I run the fire behavior module and observed the changing of the
spread. Did the s
Hi Vidura,
Just like Moritz said, you need to start by the basics about GRASS.
That said, it is better to create new raster layers than change the
existing ones.
To test other wind speed and direction, moisture, etc, just create new
rasters with r.mapcalc

Hi Pedro,
Thank you very much for the explanation. That helped me to get a basic idea
of what these files do. Then what I did was to change these files. I
changed some records in wind speed and wind direction (the files in
demomapset/cats). But what I observed was there was no change in the shape
Hi Vidura,
You need to prepare the input data to r.ros algorithm
https://grass.osgeo.org/grass74/manuals/r.ros.html
The input data needs to be in raster format.
First you need to use the standard NFFL 13 fuel models system (

Hi all,
Thank you very much Moritz Lennert for the explanation and apologize for
the mistake I've done. I will try what you suggest by myself. Hope It's
okay to questioning again if I found a problem again. Have a wonderful day.
Cheers!!!

Hi Moritz,
Really appreciate your help as we are facing this problem for some days
now. First I'm a beginner user. Can you explain what are the categories
and how those used in GRASS

We also encountered the same problem as mentioned here by Vidura. Those
data inside the wildfire data files are hard to understand. The structure
cannot be identified clearly such that what's meant by those data is also
unclear.
As we found @Vaclav Petras has done a research paper on this
Hi all,
I'm currently doing my research on wildfire behavior modeling. For that
purpose, I'm using the wildfire behavior module in GRASS GIS. I came up
with these problems in understanding the sample raster map files provided
by GRASS GIS. The content is as follows,
