Hi Dan, I have tried defining the projections to existing data points and even add new unprojected data points to an unprojected data frame to see if I can project them all to NAD 1983 Contiguous USA Albers. However, that projected coordinate doesn't align with the spatial reference of the NLCD layer (only GCS_NAD_1983 seems to work for all layers). None of the NLCD rasters, point features and subsequently interpolations seen to align meaningfully in any other spatial reference that isn't GCS_North_American_1983. This proves somewhat odd and puzzling to me since ArcMap continues to set the angular unit to degrees (0.01745329...) for anything I add not matter the defined projection, it force the cell size for the interpolated raster to [0.9548, 0.09548] as the only functional output. >I do thank you for your time and effort in helping my case, if you or anyone else have gone through similar problems, please feel free to comment.

Thank you Dan! I was afraid that could be the case. Now, if the point data is projected to GCS_NAD_83 with angular unit in degrees, which Projected Coordinate System would you recommend for the continental USA that provides "meters" or "feet" in the angular units (maybe, NAD 1983 Contiguous USA Albers or USA Contiguous Albers Equal Area Conic?). Your advise is greatly appreciated!!

Good morning! I'm running into a spatial resolution mismatch problem between the NLCD land cover raster (30 meters or 100 meters cell size) and my interpolated rasters (Ordinary Kriging and IDW with a default cell size of [X = 0.096577988, Y = 0.096577988] developed using bird point data from the lower 48 states. I have even tried to manually set the resolution for the interpolated rasters during the analysis to 30 or 100 meters, and by doing so, the interpolation analysis won't yield an output raster. It might be some technical aspect that I'm missing or conceptually something else. Any leads regarding this will be greatly appreciated! Cheers!
