I’m a junior GIS developer and working on an Angular + OpenLayers based WebMAP Application and i am using GeoServer in order to show my geometry data on my map with WMS, WFS URLs. I’ve downloaded a sample shapefile(shp) data that shows all the cities on the world with Point(the_geom) data and stored it in the my GeoServer. I applied ” Stacking / Clustering Point ” on those Point geometries with OpenLayers Codes ( ol/clusters) without problem.
