Kalindu, First, I have never done any wildfire modeling and I am not familiar with the process in GRASS. So, I'm not sure what the requirements are in GRASS to do this. However, I do not understand how 2 columns of data can contain "starting point of the fire, slope, wind velocity, wind direction, elevation, fuel models and fuel moisture" unless the data are in separate rows; but that does not make sense either to me. Is the "starting point of the fire" in lat/long coordinates or some other geographic coordinates?
I really think it would be helpful to see an example dataset with an explanation. I or others can help you with answering questions about importing your datasets, but not without this information.
