Nokia is not the first name to come to mind when you think of mapping but their new Nokia 3d maps produces some of the most stunning maps I have ever seen. It is free.
Here is a sample:
Below is a video of the live rendering of a map of downtown Toronto. Notice how every angle of each building is rendered - this is something that I have never seen before
Applications for shopping center and retail locations are numerous. It can provide a sense of the property that is a step up from google maps or pictures. Best of all it's free.
To view the maps, go to: maps.nokia.com
You need the latest version of firefox or chrome to view. Several major cities are available.
