Abstract

With the explosion of virtual globes (GoogleEarth, WorldWind, Microsoft Virtual Earth, etc.), visualisation components have to offer unlimited area capacity with, every day, new attractive functionalities to have a worldwide playfield. Combining the space and the time naturally leads to visualisation components being able to manage both static elements in the space and dynamic elements in the time. Based on its technological expertise in this area, VEGA presents a complete and modular approach which adds a new dimension to everyday client system.

This solution is composed of different proven technological components, each of them bringing the needed functionalities to fulfil the user requirements. These components may bring a worldwide 3D extent to the client system via VEGA GlobView. This is the component for accurate, real time, 3D geospatial navigation. It extends high performing, geospatial viewing by providing the necessary framework to build unlimited and realistic 3D worlds. It handles a wide range of commercial and government geospatial/3d file formats and supports access to remote data over the web.

GlobView will be used to visualize interactively in 3D the GLOBCOVER product from the European Space Agency (ESA) that provides a land cover map using as its main source of data the fine resolution (300m) mode data (FRS) to be acquired over the full year 2005 by the MERIS sensor on-board the ENVISAT satellite.
