I'm using the Surface Difference tool in 3D Analyst for the first time and it is producing some unexpected results. I'm comparing the surfaces of two TINs which are identical in structure, but with different Z values.
I'm using the tool to create a raster off the value differences between the two TINs, and this raster is doing something strange at the boundary edge (see attached image). Both rasters have values (see Identify image) so I do not understand why the difference raster has NoData.
Anyone seen this issue before? Any ideas how to resolve it?
Thanks.
