ED GIS is an amazing issue. I´m working on the Open 3D GIS project.
The ideia is to use open source and open standards to a Web 3D GIS.

I have published an article in GIS Development in a special edition about

> * open source networked geodata -libraries and feeds- of raw sensor

> * geo metadata models - formal ontologies, logical description, as
> frameworks for mining informal users' tag systems
> * geo server and middleware models for efficient saving, searching, and
> sharing of all kinds of geodata
> * sensemanking inference and other spatial intelligence
> * rendering  software for combining many sources of geodata into unified
> useful views for many kinds of interaction
> * user software/ sharing/saving/serving/searching/rendering
> * human interaction systems,  avatars and social nets,  gis, mobile gis,
> 3Digs,  geoaudio, augmented reality, haptics
> * autonomous sensor networks processing geodata.
