I am currently working with a DEM with a cell size of 10 meters. I only needed a certain area of this DEM and wanted it at a 1 m cell size so I extracted by mask. I set the appropriate environmental settings to obtain a cell size of 1 m and my mask layer was also set to 1 m cell size (same coordinate system as well).
My output does indeed have a cell size of 1 m, but you can see from the following image two different sized cells. Along the edges measure 1 m, but the cells in the middle measure about 8 meters (this is the cell size of the original DEM before I clipped it).
I'm wondering if my clipped DEM does in fact have a 1 m cell size or is something wrong here?
The point of setting my cell size at 1m was to obtain a smooth look. Possibly those larger cells really are 8 1m cells, all of the same values? I have tried resampling with bilinear interpolation and I get the exact same result.
I am using ArcGIS 10.5.1 Version 10.5.1.7333.
The most similar question I have been able to find, but which did not seem to have a final solution/one that solves my particular problem is Cell size (10m) in Raster properties differs from measured cell size (20m) in multiband (Sentinel) raster?
