Hmm... probably neither? At least, not if you are issuing a new request each time the user moves the mouse. Ideas: - use GetFeatureInfo, but issue the request only if the user position changed enough from the last position (2-3 pixels?) - use GetFeature, but load a larger area in the client and then hit that one until the mouse position gets out of the previously loaded area. The tricky part si balancing the area size with the need to keep the amount of features loaded small Cheers Andrea -- ------------------------------------------------------- Ing.
