Digital Earth Exchange (DEX)
Digital Earth Exchange (DEX) A network of supercomputers, led by the Japanese Earth Simulator (the world’s largest computer) and the San Diego Supercomputer, led by the Visualization Center of San Diego State University form a backbone for the operation of multiple “geobrowsers” and the appropriate resources of large area geo-referenced data sets.
Protocols and established documentation
procedures are being developed in conjunction with the Electronic
Cultural Atlas Initiative led by UC Berkeley and the Digital Alexandria
project led by UC Santa Barbara. This Digital Earth Exchange
network will function as the repository and server operations center
for the performance of geobrowser tessellation engines, including
NASA’s World Wind, GeoFusion GeoMatrix Toolbox, and other
commercial “digital earths.” This will enable
thin-client performance via the network and public access to the
information and computational resources.
