Environmental Space and Time Web Analyzer.

The constant update of more accurate and detailed images and the ability to customize the content through the direct mapping on the globe of any geographically localized phenomenon (physical, environmental, social, etc.), has been increasing not only the common and popular use of virtual globes but has also been offering great opportunities for geographical representation and analysis in science. The paper presents a 4D environmental data viewer (3D location of the variables at different times) using the opensource virtual globe developed by NASA (NASA World Wind). The viewer implements an innovative solution based on a doxel approach for modeling environmental variable distributions.
