Hi,
I tried to create Raster Mosaic Overview I got this message during geoprocessing
"Distributing Mosaic data set operation across 2 parallel instances on the specified host "
some images are partially invisible. how can I fix this error thanks
"Distributing Mosaic data set operation across 2 parallel instances on the specified host "
This is not an error. One geoprocessing operation can use multiple parallel instances depending on the capability of the machine. You could manage it using Geoprocessing > Environments > Parallel Processing.
What version of ArcMap are you using?
You could check this link
I am using ArcMap 10.3, The building overview shows the gape as you can see with the attached image in last message. why some area is missing?
