OGC Network™ is a window onto the dynamic, constantly changing geospatial web as described by the OpenGIS® Reference Model (ORM). Multiple communities of interest for research in geospatial interoperability are supported, and persistent demonstration capability is provided. Here you will find the latest information on OGC-compatible software, services, and information models (e.g. GML profiles, SLD examples, etc.). From this site you can quickly locate OGC-compatible geospatial web services, the latest XML schema documents, discussion forums, conformance testing resources, and GML profile working areas. Instructions on signing up for authoring privileges are on the help page.

A 3D-Earth viewer enables navigating through the virtual environment and can be easily downloaded from the internet. How might this rapid development support steady, long-term development of institutions such as Rijkswaterstaat, the roads and water regulatory authority of the Netherlands? The authors consider and compare three standard 3D-Earth viewers: Google Earth, MSN Virtual Earth 3D and NASA's World Wind. Each is combined with Open Geospatial Consortium (OGC) Services to examine their performance in disseminating geo-information to the general public. While Google Earth proves technically superior, other aspects must also be considered.
