This video demonstrates the latest update to the Simple GIS Server Admin plugin that allows you to use point cluster symbology when publishing a web map application from your Simple GIS Client project to a Simple GIS Server instance. In version 15.4.0.1 of Simple GIS Client, support was added for cluster symbols for point feature layers. Now, the latest version of Simple GIS Server Admin plugin has been updated such that if you have specified to cluster pts in your Simple GIS Client application, this will be honored, and pts will also be clustered in any resulting web map application published to a Simple GIS Server instance.
