How can I publish a mosaic dataset as a map service, without using an Image Server license?
Arcgis Server 10.8
In order to publish a mosaic dataset as a map service, you need to have an ArcGIS Server site licensed with the Image Server role.
As a workaround, you could export the mosaic dataset to a single raster dataset using the Mosaic to New Raster tool: Mosaic To New Raster (Data Management)—ArcGIS Pro | Documentation.
This way, you are publishing a single raster dataset as a map service, which does not require an additional license for ArcGIS Server.
Hope this helps!
Thank you very much for your guidance.
I have a doubt, my images are more than 2.5 TB, is it possible to publish? Is there a limit to publishing as a map service?
publishing 2.5 TB of Data through properly structured MosaicDatasets/ImageServices is not a problem as such. (Just an example: The Sentinel-2 Service from the Living Atlas is a MosaicDataset with 4 Mio records, so referencing 4 Mio Sentinel-2 scenes with 0.5 to 1 GB each, updated every night). The performance will mainly be defined by the data structure of your Images and the storage access speed (storage/network) available. If you have never dealt with those topics, you will find good guidance in the help system and even more so in the ArcGIS Imagery Workflows | Documentation. There is a What are Imagery Best Practices?—Imagery Workflows | Documentation section about formats and organization. You might also contact your local Distributor for assistance.
Note that if your imagery just natural color images and you don't need any of the dynamic feature of an image service (IE you are just looking for the image as a background image in webmap) then you can create the mosaic dataset and just convert it to tile cache and publish it directly to ArcGIS Online. See (Serving Cached imagery). No Image server is required for this, it can be done directly in ArcGIS Pro.
