Virtual Planning

Virtual Planning is producing innovative systems forintegrating and presenting all form of urban and

environmental data:- Spatial, Thematic andAdministrative

Virtual Planning is part of the Research Institute forthe Built Environment, BuHu

BuHu has the highest government rating, 6*, andreceives 25% of UK Built Environment research

funding

Virtual Planning Projects

IntelCitiesIntelligent Sustainable Cities

EU IST funded project (6.8 Million Euros)

Started January 2004

The project goal is to help achieve the EU policy goal of theknowledge society

Undertaken by 75 partners including across Europe

- 18 cities (Manchester, Rome, Barcelona, etc)

- 20 ICT companies (Nokia, IBM, CISCO, Microsoft, etc)

- 36 research institutes (University of Salford, CSTB, UPC,etc)

To illustrate the objectives of this work we propose the following scenarios:

Gaudi Bank (headquarters: Barcelona, Spain) wants to set up

a training centre to service Gaudis UK BranchesJactin House in Manchester is to be assessed as the possible

training centre

Purchaser and property developer need to assess the

surrounding environment

Architect and refurbishment professionals need to assessthe construction work

Building Data Integration SystemPart IIIPart III

What kind of data is needed?

Spatial data: 2D maps, information-rich 3D models with detailed buildings,surrounding terrain, and attributes.

Thematic data: various themes of urban environment like noise, flooding data

etc.Administrative data: information about planning regulations, planning process

management, public participation etc

What kind of operations are needed:Currently various GIS and CAD systems are used in public authorities and

planning departments / offices with different data formats (dxf, dwg, gis-files,etc). Data sharing and exchange has to be an automatic process. Also various

datasets have to be integrated into comprehensive information

Challenge:

How to share and integration the urban planning datasets which are heterogeneous,cross-domain and cross-organisation?

Prototype Development (2)Building Feature Service (BFS):BFS supports the access and use the CADdatasets on Web. Data sources could beIFC/IFCXML, DXF, DWG files.

BFS allows a client to retrieve and updatebuilding features. The exchange format betweenWeb-based BFS client and server is based onthis CityGML

Web Feature Service (WFS):GeoSever (open source)

MediatorMediator is developed to merge the two queryresults from WFS and BFS, into a new XMLdocument which is CityGML schema-based
