I have web map, created in the combination of: ExtJS 5, Openlayers 2, Geoext 2, and Geoserver.
My layers are in postgis linked to geoserver.
My scenario are 1 base map, an 10 normal layers. Actually i have a tree panel and i can view correct all the layers in the viewport.
The idea is the user click a point in the map and in someplace also input the meters to make a buffer of that point. Next i need to get a list of all the features of my 10 layers that are inside that buffer (ring).
How can I achieve this?
