ESRI 3D EARTHQUAKE GLOBE VIDEO UPGRADE
The following organizations participated by contributing funding or source data: the National Aeronautics and Space Administration ( NASA), the United Nations Environment Programme/Global Resource Information Database ( UNEP/GRID), the U.S. Later this year, ESRI will release a huge upgrade of its flagship desktop GIS product, ArcGIS, which will let users publish virtual globes on the Internet and analyse their data in many ways. Geological Survey's Center for Earth Resources Observation and Science ( EROS). GTOPO30, completed in late 1996, was developed over a three year period through a collaborative effort led by staff at the U.S. Detailed information on the characteristics of GTOPO30 including the data distribution format, the data sources, production methods, accuracy, and hints for users, is found in the GTOPO30 README file. For easier distribution, GTOPO30 has been divided into tiles which can be selected from the map shown above. GTOPO30 was derived from several raster and vector sources of topographic information. GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer).
