How long it takes to Add 400 Orthophotos to a Mosaic Dataset?

[Y_Chau]

I want to create a mosaic dataset with 400 1m pixel size orthophotos. Each image is about 1 GB and 20,000 x 20,000 rows and columns. I created pyramids beforehand. Now I am trying to add these images to a Mosaic Dataset. For hours it just stays at 0% with messages in attached picture. I am using ArcGIS Pro on a 64 GB Xeon processor. Any idea if this will work?

Sincerely

A few questions for you: 
1.  Are you adding the mosaics to a mosaic dataset in a file or enterprise geodatabase?
2.  Is the folder of raw images on a shared network drive or on your C: drive?
3.  Is the target geodatabase on your C: drive or a network share?

Hi Robert

1. It is a file GDB.
2. Both mosaic dataset and raw images are on the same drive. 
3. It is not a network drive and not C. Just another partition on the one storage drive.

Thanks

Okay - thank you for the details.  Let's try this workflow - instead of adding all 400 raster datasets in one operation, break them into smaller groups - say 50 or 100 - and see if the process completes.  If so, then load another group of 50 or 100.  Repeat the process until all 400 images are added.  What is the result?

Hi Robert

This customer is using named user licenses from portal. It seems there is some latency in their network and the client machine loses connection to the license server. I added fewer images at one time and I was able to complete Add Rasters task. I got stuck again at Build Overviews as I cannot build overviews in batches.

We moved the license to the local machine and everything worked fine. Problem is that Pro does not prompt about when the process gets stuck.

I also tested by using a license in AGOL and with a much smaller dataset. If I disconnect the machine from internet the process gets stuck. Ideally Pro runs for 60 minutes when disconnected from license server. Does this mean that I can only use Pro to view data and probably save the project during these 60 minutes? Is running GP Tools not permitted in this duration?

Hi @Y_Chau - correct, ArcGIS Pro, to my knowledge, will not open a "stalled process" UI if something goes awry.  When ArcGIS Pro is disconnected from the ArcGIS Pro Online Portal, you have 60 minutes to reconnect.  If you fail to do, ArcGIS Pro will close.  This is expected behavior.  So if a GP tool is running longer than 60 minutes, it will close the process with the application.

Hi Robert, once I took the license offline, the process completed in 5 minutes. Why would an online license abandon a process if it takes fewer than 60 minutes to complete?

Hi Y_Chau - good to hear that the offline license worked well for the process.  I wonder if your online connectivity is an issue (i.e. drops and comes back?)  between ArcGIS Pro and the ArcGIS Online Named User Licensing model.  Hard to really know via the Esri Community site.  But yes, if it takes less than 60 minutes, it would/should be fine.
