Hello,
I have a 2D polygon file and an EDM file. I already converted that 2D polygon to 3D polygon with Z value from the EDM surface elevation. Now I want to create another polygon file based on that 3D polygon file with the elevation of each vertice 5-foot higher than the original one lying on that EDM surface. I am sorry I cannot explain it very well.
Maybe I should put it this way: I want to find the nearest grid cell that has an elevation 5-foot higher than the elevation of each vertice of the polygons. Thanks.
