Re: Ovi Map S2D file format
its basically internal file for the application, and likely the format is not published anywhere. You could maybe ping Jason fox : [url]http://www.developer.nokia.com/Community/Discussion/member.php?837214-jasfox[/url] he would be located in Berlin and knows the maps contacts better.
anyway, not certain whether there is any ways on accessing the information, anyway, I would suggest you to prepare to prove that what you are really needing the information for, as well as why.
