Why is it important to have these venues mapped? According to Nokia, people spend 90% of their time inside, and that figure is rising. Altogether, Nokia has 235 square meters of inside locations mapped. As for the future, the last "frame" shows a roller coaster and Ferris Wheel which means that Nokia will probably be mapping theme parks soon. NAVTEQ, the company that powers Nokia's maps, started inside mapping earlier last year with over 200 of the largest shopping centers in the U.S. included.
