I'm using ArcMap 10. I want to display the area of simulated avalanches. I want this area to be divided in different colors depending on the thickness of the deposit. I managed to do that. But I want all the simulated avalanches to refer to the same scale and same legend of thickness. This means that for every simulation a certain range of values of thickness (e.g. from 2m to 4m) falls within the same color. The problem is I need to transform my raster into polygons (for future calculations of area ratios) and to do this it must be integer. So I guess I have two choices: "raster calculator" or "reclassify". With "raster calculator" I see I obtain my integer raster with the number of classes of thickness I want but the areas are changed a bit (I don't know why). With "Reclassify" I obtain an integer raster where my areas are essentially the same as before, but it can have a number of classes not higher than the value of thickness it reaches. In other words using the "reclassify" tool I would have each simulated avalanche with its own scale of thickness and not a common thickness for all my simulations. Is there a way to accomplish what I'm looking for? I hope I explained it clear enough (It's a bit hard to explain this even in my own language).
