Abstract: NASA Goddard's Digital Earth Workbench is an interactive system that allows those interested in geospatial information, especially NASA scientists, to retrieve, view, and compare large amounts of Earth related information. For scientists, it is a tool to identify the intricate correlations among the various geological, biological, climatic, and ... civilization forces that affect the Earth. For others, such as museums or the general public, it is a tool for teaching and exploring.
The system offers an interactive computer program that allows users to easily navigate the globe to view satellite imagery and topography of any location on Earth. The user can add additional data "layers" of imagery and control the blending between layers. Three dimensional objects (e.g., a building model or a representation from a computational model) can also be imported and displayed. Extremely large images (e.g., greater than 100,000 x 100,000 pixels) are supported, and the system can retrieve information stored at remote sites using standard protocols such as http and ftp.
