i have a dem to intepolate , im tryng interpolate this data with Natural neighbor using a maks to select a small part of the data , how make this im trying select in enviroments > raster analusis > maks and select a polygon of select area , but dont works
It might help to check that both your DEM and your polygon are both in the same projected coordinate system. If not, reproject one of them. See if that works.
You might also try using the raster clip tool in your Toolbox to use your polygon in clipping your DEM. The resulting clipped DEM should conform to the shape of your polygon.
It does not honor MASK by design. Natural Neighbor also does not extrapolate data outside the convex hull. According to the help the only environments that are honored are Cell Size, Current Workspace, Output Coordinate System, Extent, Scratch Workspace, Snap Raster
