Something to consider would be to use the GD graphics library to generate the tiles on demand.
For this to work at a reasonable speed, you'd need to load your information into a database in a way that makes it possible to efficiently retrieve the text that might be needed for an individual tile. I.e. you need the lat/lng information to be a database index, so that it doesn't have to read through thousands of entries to find the ones that are needed. Then you can write a server that reads the tile parameters, scans the database for any entries that might be required (allowing for the fact that the text might overlap into this tile from a neighbouring one), use GD to render the tile image and return it to the client. There's an example of this in the book: "Beginning Google Maps Applications with PHP and Ajax". Their map looks like this: http://googlemapsbook.com/chapter7/ServerCustomTiles/ and the individual tiles look like this: http://googlemapsbook.com/chapter7/ServerCustomTiles/server.php?x=115&y=1 94&zoom=9 Their database contains over 115,000 entries. -- 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.
