Hi Phil,
Not sure if we understand eachother correctly. My point here is: I need
stuff tot hover over :)) So, I don't see how I could be fetching geometry
on hover.
Otherwise, I guess I'm on a similar track as you're pointing at, thanks.
By the wat, since JS is so slow, I'm choosing GeoJSON over WFS/GML.
