I have several examples of Perl programs that generate tiles from data in the workshop. Those programs, along with the data and everything else in the workshop are available for download from: http://www.usnaviguide.com/ws-2008-02 - look for the file named download.zip or something of that nature.
As for creating one humongous image and breaking into several tile layers, you'll have to consider that at a lower zoom, the features will appear extremely tiny and lines barely visible or not at all. Also, beyond two levels higher than the natural zoom of the image, features will start to be pixelated. A better strategy would be to produce several images, each optimized to view at the natural zoom of that image so features appear the correct size. If you do this, you can also select which features to display at that zoom level, which will make it more meaningful to the user. For instance, in a wide view of the US, very few if any cities are shown, in a zoomed in view of NYC, parks and main streets are shown. It's just more usable that way. -John Coryat http://maps.huge.info http://www.usnaviguide.com http://www.zipmaps.net -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
