Hello. This is my first post so thank you in advance for your help. I have two TIN surfaces for a landscape from two separate years. I want to create a map of the ELEVATION change between the two years. I have used the surface difference tool but it only returns erosion(cut) or deposition(fill). The information in the attribute table seems too coarse to create a good map. Does anyone have advice on how to generate a map of the elevation change between the two years?
Thanks! It looks as though that will again give me a gain or loss. The map is better then because it is by pixel. But I'm not getting an elevation change like I have seen in AutoCAD. Would you suggest that I then use the attribute table to calculate the elevation change since it returns a table of area and volume cut/fill?
Do you have spatial analyst? To get actual difference values, I'd look at converting your TINs to elevation rasters and then using some raster math to work out the difference (i.e. higher raster minus lower raster).
I've always found it less than useful that the Cut/Fill tool doesn't also output the actual differences between cells too.
