I'm trying to merge raster tiles that all have the same, but unequal cell size (X: 2,8, Y: 2,9). When I use the Mosaic To New Raster tool, I can enter ONE cell size which either results in a raster shifted in X or Y-direction or a black line going through the resulting raster when I don't specify anything. Is there any way to get around this?

  • you may always reclassify your rasters into equal cell sizes (i.e. 3x3)... why is your cell size unequal in the first place? – dru87 May 4 '16 at 13:31
  • That's how I got it, and I'd rather not fiddle around with the cell sizes.. – MapEngine May 4 '16 at 14:31
  • Load to mosaic dataset and clip it by bounding rectangle? Never tried it myself though – FelixIP May 4 '16 at 21:46

If you don't have to work in an ESRI workflow you can try the gdal merge tool from the GDAL toolset (http://www.gdal.org/gdal_merge.html). I'm pretty sure this will allow you to use floating point numbers for your resolution. I've had trouble with this tool if you are using very large rasters but if they aren't too large it can work well.
