If you already have a GeoServer WMS service, then the most straightforward way is to use the getFeatureInfo capabilities of the WMS protocol. See https://github.com/heigeo/leaflet.wms and http://docs.geoserver.org/latest/en/user/services/wms/reference.html#wms-getfeatureinfo

  • Thanks lvanSanchez,... but if i also want to display other information related to each polygon in popups from Postgresql DB rather then PostGIS then what are the options ?. I want to display small picture related to each polygon and some attribute information which is stored in RDBS. Thank you

  • If you want to rely on your WMS: Click on map → get some ID of the polygon where the user clicked → use that ID to request the picture → display the picture.
