I'm currently developing a web mapping application using Django/GeoDjango, Postgres/PostGIS, and OpenLayers. The end aim is to enable the analysis of property data, so I'm needing to visualise upwards of 30,000 polygons at a time. I'm wondering about my options for dynamically generating thematic maps with this many polygons. Currently I visualising some GeoJSON layers that contain as many as 60 geometries, but I'm not sure of the upward limit for GeoJSON. If WMS is the way to go, can Geoserver be used with Django view functions to dynamically create and symbolise map layers? With a geoserver WMS is it possible to select multiple features on map? Is it also possible to edit feature information?
Thanks in advance for any advice on this.
