Those dots are not GMarkers, they're a GLayer. That layer consists of three parts:
1. A GTileLayerOverlay that displays tiles like this: http://mlt0.google.com/mapslt?lyrs=lmq:8:pizza*,|s:11259793464583361879 9|h:2b|cc:FR&x=4147&y=2817&z=13&w=256&h=256&gl=fr&hl=fr 2. a mechanism for obtaining the infowindow details for clicked hotspots 3. a mechanism for changing the cursor when the mouse is over a hotspot At present there's no interface for creating custom GLayers, so to do the same sort of thing you'd have to do the three sections separately. 1. You'll need a server that can search your database and create a suitable tile image with just the hotspots shown. Use that server to supply the tiles for a GTileLayerOverlay. 2. The easiest way to do that is to listen for all map clicks and send the coordinates to a server which scans your database and returns the infowindow details if there's a hotspot at that location. 3. Is quite tricky, but has been discussed in the group before, so search the group when you get that far. -- Mike Williams http://econym.org.uk/gmap --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
