One way to do it is to create a large image, that spans multiple tiles, and then cut it into individual tiles. Another way is to load the line data, calculate the corners of the MBR, (Minimum Bounding Rectangle), and for each corner determine what tile it is on. Then paint the same line on each tile that is inside those bounds. Admittedly, it is not for beginners. > > Wait a minute...

Yes, if you put some of the work on Google's servers, then your own machine will use fewer CPU cycles, but it will also take longer time to transmit things back and forth, so the overall performance of your aplication will be slower. And in any case, there is some size limit to the KMLs that Google will process. I just can't remember how much. -- Marcelo - http://maps.forum.nu -- --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
