I am attempting to make a model to show cost surface on the water in order to model potential pathways for a ship. I have wind speed and direction data for this. GRASS seems to have the code that I would need. I would like to use their Wildfire Modeling/ Anisotropic Spreading code, but I would like to manipulate it in Arc. (Attached is the article which brought me to the conclusion that this is what I need.)I don't know the first thing about coding, and my experience with GRASS is limited to say the least. Does anyone have advice on how to get a cost surface on water which is iterative or how to get the code from GRASS?
Thank you,
Phebus
