问题
I\'m trying to get (specified) region borders as GMaps coordinates (to form a polyline) from Google Maps. Is this possible in some way? (either from maps.google.com or my own GMaps in my own domain).
Note: I know you can draw/outline regions manually with tools intended for it (like http://www.birdtheme.org/useful/v3tool.html), but covering a large region ACCURATELY is a ton of work. The draw-it-yourself answer is not an option in this case.
Example:
- https://maps.google.com/ -> type in \"Uusimaa, Finland\"
- You can see the pink-ish border that outlines the wanted region
- That border is the polyline that I need the coordinates of
Requirements:
- Extract the region data coordinates (if available) from a given search (as in the example)
- If the previous is not possible, a source to an ACCURATE map of the region \"Uusimaa, Finland\" is required (plain googling did not yield needed results).

This is becoming a FAQ. See the replies to these questions:
Add "Search Area" outline onto google maps result
Google has started highlighting search areas in Pink color. Is this feature available in Google Maps API 3?
