Hi All,
I am wondering about any approach to re-publish cache service after adding new images to its source mosaic.
Thank you
Best,
Fatin
You can create footprints for the areas with new imagery and regenerate the cache for only those areas. See Map cache updates—Documentation | ArcGIS Enterprise
Thank you FC Basson for your answering.
just to make sure that i got the right answer : do you mean that i can edit the published cached service without any need to re-publish it ?
Fatin, are you asking about actually changing/expending the service's footprint? If so, I have the same question.
If not, that is, if you are just refreshing areas, than FC Basson option it the route I would try.
I would also check out Image Management and Image Management Workflows | ArcGIS Resource Center
Hi Rebecca,
yes i have the same question"changing the service footprint/adding new images to cached service/edit publish service with or without any need to overwrite existing service???".
If it is a cached service, I would think republishing/overwriting it is required, but only for the updated footprint areas. Otherwise if the service is based on overviews from the mosaic it should update without republishing.
Thank you FC Basson, I will try this.
Hi FC Basson and Rebecca,
Again, I am facing a new issue: I am trying to add a new mosaic data set to an existing web service.
Can I add a new mosaic data set to my current cached map service?
If possible, Do I need to over write publish it?
Kindly find the following screenshot.
What do you think?
All the Best,
My guess (and only a guess since I haven't done it), is any dynamic service using the mosaic will work fine, but any cache would of course need to be updated, I would not think you would have to update/replace your service unless the full-extent/footprint has changed.
Thank you Rebecca for your kind reply.
you said <<any cache would of course need to be updated>>. In my case how can this happen?
Do you mean that I should change the full extent ?
If I got your idea, you say that I have to start from zero to have my new extent/foorprint then overwrite publish it?
Have you looked at
What is image service caching?—Documentation | ArcGIS Enterprise on updating caches. It looks like what you may want to use is the Compute Dirty Area—Help | ArcGIS Desktop to help determine what needs to be updated.
This tool constructs a polygon that defines regions containing one or more mosaic dataset items that have been modified since a specified point in time.This allows tools and applications that depend on the mosaic dataset for the construction of derived products, such as cache, to perform partial updates since the last time the derived products were synchronized with the mosaic dataset.

and Map cache updates—Documentation | ArcGIS Enterprise for updaing
I have not had to update my mosaic/Image Server service caches yet, since they are still fairly new. But it looks like there are many other tools that might come in handy in the Mosaic Toolset (see left hand column TOC when on the Compute Dirty Area help)
