There was an error encountered when trying to read the specified grid. Problems accessing a grid are most commonly the result of missing required component files in the grid's folder. If all of the required components are present, it is also possible that the files that contain the binary raster data are internally corrupted.
- Determine whether the grid is valid first by trying to display it.
- If it does not show properly, check to see that all the required component files are present in the grid's folder.
If there is no sta.adf file in the grid directory, try creating one with the Calculate Statistics tool.
- If its data files seem to have been corrupted, you may need to re-create the grid. Hopefully, you have a backup copy that can be used, or you can run the process that created it again.
