I have six ASCII files in ArcMap 10.3 that I am trying to convert into one Raster file for the purposes of producing a linear cross-section of the height (Z) values. I have converted all six ASC files to GDB files, and also to LYR files.
However, when I try the Merge tool to create the final conjoined Raster image, I am getting the error message:
ERROR 000840 The value is not a Table View.
as soon as I enter the first Raster file to be merged.
If this is not possible, the other possibility may be Raster Calculator, but I am unsure how to proceed with a merge here.
