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.
