I have a masked raster layer (ESRI grid format) of a large area that I’m trying to clip in ArcMap 10.3. Cell size is key for further analysis, thus I need to maintain the cell size of the clipped layer to 30 x 30 (the original masked layer is 30 x 30). However, when I clip the layer, the cell size for both X and Y reduces to 29.99806155. Unfortunately, this minute change does impact my analysis, and I don’t know (a) why this is occurring, and (b) how to prevent it. I’ve tried adjusting the processing extent and cell size to prevent this change, but to no avail. Any advice?
