http://evlweb.eecs.uic.edu/pape/vrml/etopo/
--------------------------------------------------------------------------------
Note: The Map Generator does not work on the new EVL web server (the new server is a Linux PC, while the Generator is built on a set of SGI programs).
For the time being, make sure you are accessing this page through the old server's URL - http://www2.evl.uic.edu/pape/vrml/etopo/
--------------------------------------------------------------------------------
This page allows you to interactively generate VRML 2.0 scenes of topographic maps of the world. The topographic data used is the ETOPO-5 dataset from the NOAA NGDC, a 5 arc minute resolution map of topography and bathymetry for the entire Earth's surface. The surface can be colored based on elevation, or texture-mapped with various other data sets. The texture maps available are the biosphere, an AVHRR composite, the CIA World Data Bank, and the topography data (using a texture map will allow higher resolution coloring with a coarse grid).
The primary difference between this and the original VRML 1.0 map generator is that it uses the new VRML 2 "ElevationGrid" node type. This produces significantly smaller files (1/10 or better) than in VRML 1.
Use the menus and toggles below to set the size and quality of the map. To generate the VRML file, select a point on the map. The map will be centered around the point you pick; it currently will not wrap around the 180 degree line of longitude.
New: Because some browsers have problems dealing with VRML created by a CGI script, I have created a new URL generating version of this page, which returns a link to the map which you can then load. If you are unable to get a map from this page, try the URL generator.
