I have a DEM SRTM that I classify using Spatial Analyst Tools > Reclass > Reclassify.
The result is box shaped so I go to Layer Properties > Display and choose cubic convolution. The result is smooth (not box shaped).
Next I convert to polygon using Conversion Tools > From Raster > Raster to Polygon choosing Simplify polygon. Then the polygon output is boxshaped.
So how do I create smooth polygons like from cubic display raster ?
