I have a vector layer called layer_a that has attributes gid,value_class. I am styling this layer using the attribute value_class with equal interval and 10 classes.
I am serving this layer as a wms with filter on the gid column. For example if I filter the wms request with gid = 1 the range or min-max values of the value_class changes depending on that filter.
How can I dynamically style the layer using sld based on the filter keeping in mind the filter determines the returned max -min/range of data returned which needs to be used in the style.
Or if a database (PostGIS) solution exist for this classification and then I could use a named sld.
