 * Indoor support needed?

AGILE W3DS experiment
We aim to develop an experiment around 3D geodata within a Service Oriented Architecture, exploring the usage of W3DS servers.

OGC already executed a 3D Portrayal Interoperability Experiment (3DPIE). This experiment had a large a scope and explored several different workflows. Our porpose is more well deifined and focused only on the exploitation of 3D geodata served by W3DS servers.

It is a completely voluntary based initiative. Each participant should supports its own costs. Maybe some support will be available from AGILE or EuroSDR to organize a meeting, possibly next to an already existent event.

Although the scope is well defined, we still have to deal with 3 interrelated topics:
 * server
 * client
 * data

No specific use cases are defined, and partners can present use cases. Specific use cases might consider:


 * Data Editing and Data Creation
 * How users can add value to the existent data?
 * Modifying building models?
 * Positioning
 * Textures (images) upload?
 * Indoor
 * Building semantics
 * Time

Server side
The idea is to put some servers up and running with one common data set. Other data sets may exists to cover other use cases.


 * which formats (besides X3D)?
 * JSON support?


 * Possible Demo Servers
 * OSM-3D.org and www.Heidelberg-3d.de (LOD1-LOD3)
 * Demo Server on Amazon Cloud? (Sponsors?)
 * Fraunhofer IGD can set up a W3DS demo server (also providing HTML5/X3DOM) if an open demo data set is available

Client side
There are different groups working on different clients. Can we collaborate around just a few clients in the short term?


 * Client Development
 * How to collaborate?
 * How many Clients? there are different groups working on clients.
 * Feature Wishlist?
 * Some semantic might be necessary
 * e.g. use CityGML Feature Types as layers, then you can implement object specific client behavior, this needs to specified in the Capabilities
 * Shall server give hints on what can be done with the data?

Data for the experiment

 * IGN Paris Data: a formal request by AGILE and EuroSDR is being prepared
 * Rotterdam, in Dutch

Research issues
Difference between visualization models (generalized versions) versus database models

Crowdsourcing Building Models? ->OpenBuildingModels?

Common Inititives / Projects / Collaboratve Efforts

 * ClientView (details needed)
 * VicomEarth (details needed)
