The web as we know it is based on a book analogy. It started out as little more than text with hyper links. Growing more sophisticated, the addition of multimedia and databases still hasn't altered the central book analogy: a web site is still made up of web pages whatever its content.
IMHO the GeoWeb represents the first radical divergence from this form. In the early days of the web maps were static, but now they're dynamic and involve 3D models, videos and time animations. Such a media is now way beyond what can be called a 'map', but it is map based because the navigation is not structured like a book, its primarily a spatial arrangement. Which goes someway to explain why I talk about Google Earth projects on this blog and don't refer to this or that .kmz file. To me its the difference between between a website and a .html file.
A lot of the terms we use on the web are spatial or have spatial roots e.g.: website, navigation, site map and cyberspace. In fact spatial thinking and location are such a central human approachs to thinking that I wonder if the GeoWeb has the power to overtake the BookWeb. It may happen, it may not but if it does I don't think any of us has the faintest idea what it will actually be like.
Everyone have a good weekend.
