Rendering the world
Not sure if I understand why real-time tile rendering on servers doesn't work.<p>Googly clearly does not pre-render tiles and it looks like it works fine for them. Request is made, data collected, relevant tiles rendered, returned to client-side. Yes, I know, Google has $billions in computing resources, but does it really take that much server-power to render tiles? (even for 1,000s of requests/second?)<p>Is it a matter of data transfer or processing capacity? A screen sized 2048x1536 would need to load 48 tiles at a time. Google's tiles for a city avg about 14KB/tile, so 672KB. 5,000 of these a second is 3.4GB. (I'm a front-end guy so this is a little out of my league.)
