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? </SPAN><BR /><BR /><SPAN>Thank you,</SPAN><BR /><BR /><SPAN>Phebus</SPAN></BODY></HTML> Wed, 28 Jul 2010 23:46:54 GMT AngelinaPhebus 2010-07-28T23:46:54Z Cost surface on Water https://community.esri.com/t5/data-management-questions/cost-surface-on-water/m-p/215718#M12380 <HTML><HEAD></HEAD><BODY><SPAN>I am attempting to make a model to show cost surface on the water in order to model potential pathways for a ship.
