Virtual flight over river Loire / Promenade aérienne sur la Loire
This "aerial virtual tour" over river Loire and its estuary covers 140km (to my knowlege it's a record in length ???).
It was developped for the "GIP Loire Estuaire" french organization in charge of studying this fabulous environment. (http://www.loire-estuaire.org/) Scenario and texts by Stephanie Aumeunier (GIP Loire estuaire), aerial photos and virtual tour by Philippe Graindorge (Gerpho).
