Photon Research Associates in cooperation with Skyline Software Systems, i-cubed and LeadDog Consulting have created a web-based interactive 3D 'fly-through' of Athens Greece. You can visit specific venues or follow one of the predefined routes through the city.
The visual terrain data set includes DigitalGlobe 60 centimeter imagery processed by i-cubed, a 25 meter digital elevation model based on ASTER imagery from i-cubed, and vectors extracted by LeadDog.
