“build overviews” for a mosaic generates black\while tiles

JamalNUMAN

Applying “build overviews” for a mosaic generates black\while tiles,

For example, in the screenshots below, in order to let the mosaic appear in all scales, the “build overviews” is applied. However, this generates black\while tiles.

How this might be resolved?

Thank you

Best

No you really dot need a server license, try to go to geoprocessing menu > Environments then go to Parallel processing set the parallel processing factor to 1. Then try to build the overviews again.

please be aware that you need to build the mosaic overviews when you change the overview sampling factor from 3 to 5, this is related for my previous answer and has nothing to do with the server license issue.

Thanks

Jamal,

check out the links in Mosaic dataset looks like a checkerboard which has a similar issue.

it also has a link to a blog Does your mosaic dataset look like a checkerboard? | ArcGIS Blog

Thank you Rebecca for the help.

I went through the links you have already provided but it appears that they don’t provide root solution for the issue. I got no tools that that can fix it.

did you go through the comments

make sure they have defined coordinate system
they view individually fine
make a new mosaic data set
a consolidate link which suggests using UNC paths rather than absolute paths
- https://community.esri.com/thread/179498
what have you ruled out?

JamalNUMAN

Thanks Dan for the help

-make sure they have defined coordinate system (screenshot below)

-they view individually fine (screenshot below)

-make a new mosaic data set (the same issue is repeated in the new mosaic)

-a consolidate link which suggests using UNC paths rather than absolute paths (screenshot below)

-Room in mosaic data appear checkerboard pattern (no solutions are here)

Hi Jamal,

From the define overviews try to increase the overview sampling factor from 3 to 5

Thanks

JamalNUMAN

Thanks Ahmad. Not working

JamalNUMAN

Sorry. I just observed that the “build overviews” ends with error.

Do I really need a server license to apply the “build overviews”?

AhmadSALEH1

No you really dot need a server license, try to go to geoprocessing menu > Environments then go to Parallel processing set the parallel processing factor to 1. Then try to build the overviews again.

Thanks

I have tested the issue with your data and its working fine with me when stetting the parallel processing factor to 1

thanks,

ahmad

Thanks Ahmad. It works as a charm.

JamalNUMAN

This works fine in ArcMap 10.6.1

I also get this checkerboard visualization but for a different reason. My raster is stored on a server share but on my desktop, I connect to it via a letter drive connection (eg. E:/). My apps and services connect to the server address (eg. //10.1.1.2/data) so after I've added my rasters, I need to "Repair Mosaic Dataset Paths" using the geoprocessing tool and give it the server path.
