I want to display a vector layer in openlayers. Users can scale the map before they load the vector layer and I'd like to simplify the geometry with st_simplify before sending it to the client.
Does anyone have a simple formula I can use to calculate an appropriate st_simplify tolerance based on the map's properties (eg zoom, scale or extent?)?
(I don't think this is relevant but have a php middle layer and am passing the layer as kml)
I've googled around and maybe I'm looking the wrong way because I can't believe i'm the first one with this question!
thanks in advance!
