I'm doing an online ESRI tutorial on image processing, and the rasters are just giant checkerboards. I just wanted to alert ESRI to the problem, but can't find any way to do that. So, I just posted it here.
This is more likely a permissions/data access problem rather than a data problem:
Problem: Mosaic datasets display a checkerboard pattern when viewing from a different machine
Does your mosaic dataset look like a checkerboard?
If the imagery/overviews aren't available, you'll see checkerboard pattern.
That makes sense. Since this is data provided in a tutorial, it seems like a problem that ESRI needs to fix. Whom should I contact?
Sorry, what I mean is that first ensure that the data that the mosaic dataset requires is in the location it expects to be. For example, if the mosaic dataset is created with paths to imagery set to C:\mosaicDataSet\Imagery, but you extract the tutorial data into D:\tutorialData, then you'll see the checkerboard as the mosaic dataset can't find the data under C:\mosaicDataSet\Imagery, where the imagery was originally located.
Take a look at the documentation on repairing paths in a mosaic dataset:
Repairing paths in a mosaic dataset—Help | ArcGIS Desktop
It includes links to tools like the Export Mosaic Dataset Paths tool. If you know where the imagery is, and run the tool and notice the paths are different, then you can update the paths following some of the methods outlined in the doc. If you didn't receive the imagery at all in the tutorial data, then that's a problem that needs to be corrected. I'd say it's more likely the paths are not correct. If you find that the data is missing, I'd start with Technical Support.
Ah Ha! Yes, I get it now. I'll check that out.
