GLayer is a tile layer with mouse sensing. You can create a custom tile layer with your markers painted on it. You can find many examples and tutorials on the subject.
Clicks and mouseovers are the tricky part. GLayer seems to load a JSON file that includes the hot spots. The hot spots are indicated as pixel areas. The file is downloaded on demand like tiles. The information about current viewport hotspots is loaded when user mouseovers the map. I agree. A custom GLayer would be great. But that is all realistic to implement without documented support. -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
