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

How?

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

StrateGis GroepInteractive Urban DevelopmentOntology Driven Concept

Modeller● Generic modelling platform

o Target specific concept problemso Software re-use

• 2D/3D viewers• Knowledge representations (including calculation models)

o Re-use of ontologieso Interoperability

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)
