Digital Earth and Future Earth

Digital Earth

Digital Earth is a massive, distributed framework for managing and visualising georeferenced information over the Internet. Imagine being able to walk down the streets of Paris, seeing the sights and hearing the sounds around you, without leaving your home. You are able to converse with a friend who is also online, and the two of you decide to fly to Tahiti together. As you travel around the gl...

Next-generation Digital Earth.

A speech of then-Vice President Al Gore in 1998 created a vision for a Digital Earth, and played a role in stimulating the development of a first generation of virtual globes, typified by Google Earth, that achieved many but not all the elements of this vision. The technical achievements of Google Earth, and the functionality of this first generation of virtual globes, are reviewed against the ...

Future of Earth Orientation Predictions

Earth orientation prediction has undergone a number of changes over the last few decades in response to changing conditions in the Earth orientation parameter user community. However, considering the recent pace of change, it is likely that the rate at which innovations are introduced into the prediction process will increase. Potential drivers for change are discussed and possible directions f...

One-to-Two Digital Earth

The digital Earth framework is a multiresolution 3D model used to visualize location-based data. In this paper, we introduce a new digital Earth framework using a cube as its underlying polyhedron. To create multiresolution, we introduce two types of 1-to-2 refinement. Having a smaller factor of refinement enables us to provide more resolutions and therefore a smoother transition among resoluti...
