Is there a way to put map with Google Maps API to a website, but upside down? North must be down, and south up. Is there any possible way to do it? I really need to put map that way and I need really fast solution.
Not using the Google tiles. You could use CSS transforms to flip the map, but that will muck with mouse interaction and breach terms of service (modifying attribution).
I suggest using OSM tiles, and flipping tile coordinates (number of tiles in the the world at a particular zoom level is 2^zoom).
I wrote a small library to use OSM as a base map, just make the change above.
Yes it is possible.
The below was an expirement in map labs awhile back, but worked within the core google maps and was not exposed via the API. You maybe able to find out from the Google Maps labs group on how they did this?
Note that the labels are still the right way around.
If you flip the map using this method, you could always remove labels using the v3API styled layers.
Using the Google Maps API (Flash Version) you can rotate the maps
