SRI International is a research institute with interests in engineering, information technology, and a variety of other fields. One of its current projects is dubbed Digital Earth, an effort "to create an open infrastructure that allows anyone around the globe to publish or to search for data based upon a specific location." This report describes the multiple technologies that are being integrated into the project, like GeoWeb as the information database, GeoVRML as a three dimensional geographic data format, and the 3D browser called TerraVision. All of the digital images and illustrations included in the report make it quite large; so, it is best to have a fast Internet connection to view it.
