Thanks Nianwei. I believe this is a very important feature that Google Map API needs to support. There will be more and more people start using custom projection as it will provide a lot of benefits. -- You received this message because you are subscribed to the Google Groups "Google Maps Ja

resoulition0 is something specific to the tileset I used in the sample, it may not apply to you at all. If the tileset's zoom level is not same as Google's level, say, it's level 0 is really equivalent to Google's level 10, some sort of z level shift is necessary for tile coordinates. The important

Thanks Nianwei. The sample code is great for me to start with. I studied the code and am a little bit confused with the variable resolustion0 (default value 1024). I understand all the calculations related, based on which I assume it should work with different valuse like 2048 or 512, but it d
