The technology for doing that was all described in the "Beginning Google Maps Applications" book back in 2006.
http://googlemapsbook.com/chapter7/ServerCustomTiles/ What you have to do is write a server that accepts requests for tiles and searches through the database for entries that are in that tile, then uses gd to construct the tile image. The only differences from what's in the book are: The idea of storing a mini-thumbnail of the image in the database rather than using the same icon for every point. Needing to perform a database search that's a few pixels wider than the requested tile size. The example doesn't actually perform any click handling, but the book explains that you can send click requests to the server and have it return infowindow content. See also: How GLayers Work http://econym.org.uk/gmap/howglayerswork.htm Even if Google does implement the GLayer("com.povo.popular") syntax on the client side, you'd still have to do all the tile creation and infowindow service on the server side. Without that syntax, the client side code is just a custom GTileLayerOverlay() and a GDownloadUrl() request for the click handling. [The book uses a custom GMapType, because GTileLayerOverlay didn't exist in 2006, but the principle is exactly the same.] The only thing you don't easily get with that technology is the cursor changing when it passes over a hot spot on the tile layer. It looks like the GLayer server might also return a list of hot spot locations, and the client side code compares the mouse position with the list of GLatLngBounds of the hot spots. The code that does it is extremely obscure and I can't see the details. -- http://econym.org.uk/gmap The Blackpool Community Church Javascript Team --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
