Developer● 3D-model of present situation with semantic

annotationso Function, physical stateo Financial & legal datao Environmental data

● Intelligent 3D-object library for spatial objects with predefined annotated default objects on several spatial levels (area to constructions)

● 3D-object creator: automated annotation with data

● Assessment: embedded state-of-the-art financial and other models

Objects and their properties

Levels of Detail

Intelligent urban objects● More than 200 different

urban objects● 10-50 properties per object● Approx. 10 types of objects● Integrated with financial

and sustainability calculation models

● Reports for each object

Integrated calculation models

●Land planning●Real estate●Urban Area analyses●Parking●Sustainability Assessment

The model: Project surroundings

Overview of the model

Live Calculations

Ongoing Development

●Civil engineering domaino Undergrond modellingo Water management in city centres

●Cradle to Cradleo Integration with MEDIAo CO2/NO2 maps (together with DEERNS)

Semantic Web for Urban Development Assessment

Hans Schevers15 August 2006

Slide Presentation Title

By automated multi disciplinary assessments at every stage of the design process

Improve the quality of designs

by a truly integrated design approach

Research goals

A software framework for enabling inter-operability

Our research focus?

Research focus ● Automated assessments Urban Development

o Master planso Neighbourhood designso Building designs

● Multi disciplinary and interdisciplinaryo Multi disciplinary applications and knowledgeo Identification of inter disciplinary relations

● Barrierso The shear complexity

• decomposition, abstraction and characterisation, semantic differences of engineering information

• Calculation/knowledge dependent relationships and conflicts

Semantic Web

● Next generation of the interneto Based on the current one

● make data on the web more machine-interpretable o Platform for

• collaborating web services (grid computing)• Agents• interoperability

o Computer encoded ontologies• Consistency checks• Inference support• Interoperability support

Semantic Technology example: a family database

Example: defining a child

Example: defining a daughter

Example: defining a nephew

Ontologies driven concept modeller

● Ontologieso Rule ontologyo Decision table ontologyo Geometry (instruction) ontology (input output)o Chart ontology

● Domain ontologieso Urban masterplano Neighbourhoodo Sketch building designo Water supply pipe systemo Solar energy efficient subdivisions

Script rules

Concept Modeller: urban masterplan

● Ontologyo Classes: dwellings, public parks, roads, officebuildings, parking

spaceso Properties: amountOfPersons, water demand, pervious area;

● Knowledgeo Default values

• Dwelling sizes per type, water usage per person, water usage per m2 garden, cost price, rent price

o Geometry instructions• distances dwellling to shoppingcenter, public transport, public park

o Aggregation rules• Amount of people, parking spaces, density, dwellings, costs, rents,

average distance to shoppingcentres, public transport,park

StrateGis GroepInteractive Urban DevelopmentRating of Development

• Methodology for rating developments considers:

• Lot orientation

• Lot width

• Slope

• Determine star rating

Concept Modeller: Solar subdivisions

Conclusions

●Semantic Web seems very usefulo Great effort to implement ito Rather slow uptake

●Urban Developer moving slowly towards Semantic Web implementation

●Semantic Web GIS implementationo Jump starting Semantic Web development?

Next Steps

●StrateGis is open for collaborationo Participate in R&D projectso Forming consortiums for ‘larger’ projectso Ensuring quality (Scientific background)
