At its Nokia World event that's seen the launch of the new N97, Nokia has released the latest beta version of its mobile mapping and navigation service, Nokia Maps, as well as its personalised online mapping experience on Ovi.

Nokia Maps has been updated to include a number of new features such as high-resolution aerial images, 3D landmarks for 216 cities and terrain maps, as well as a new route overview.
