Flat map -> Google maps

[crypto...@yandex.ru]

Hello !

I suggest the function for Google Maps:

Conversion of coordinates from proprietary flat-cartesian maps with
arbitrary datum, into Google maps.
Interface: copy URL from proprietary map, paste it into Google Maps
search form, hit "Go" button.
Implementation: database of proprietary maps sites world-wide,
recognition of URL beginning, coordinates conversion.

Example. i wrote one in JavaScript, just because i needed it hard.
Russian language (since the place i made it for, Moscow, is in
Russia), but JavaScript is pretty international

Proprietary maps site: http://maps.yandex.ru

I'm looking forward for comments on my work, from Google staff
responsible for maps and from users too.
