I have a PostGIS database with a table with point geometry. I am showing these points through Geoserver using OpenLayer2.13.What I want to do is to create a buffer around these points.How can I do this on the fly? For example a user selects to create a buffer of 100 meters around each point. I want to redraw() the Openlayers and show this information. Or to add a new layer with this buffer.My question is in which level should I do this. In the geoserver (through SLD if possible) or in Openlayers? And how can I do this in each case?
