3D enabling Smart CitiesFederico Prandi (Fondazione Graphitech)

“A smart city provides interoperable, Internet-based government services that enable ubiquitous connectivity to transform key government processes, both internally across departments and employees both externally to citizens and businesses” (Al-Hader, 2009).

Cities in particular are most challenged

The challenge is to deal with the social, economic and environment consequences of this development through more effective and comprehensive land administration, supported by effective Spatial Data Infrastructures

There is an ever-increasing demand for the collection, integration, management and sharing of reliable spatial information

Gis vs. Google Earth vs. Google maps

Maps data MashUp

3D City Information

The latest generation of 3D Urban Information Models (UIM), created from accurate urban-scale geospatial information, can be used to create smart web services based on geometric, semantic, morphological and structural information at urban scale level

Use of 3D model standard in the context of Smart Cities

Smart Cities and CityGML

LoD Described features0 FootPrint1 Block model w/o

roof structures2 Building model with

texture and roof model

3 Detailed architecture model with external doors and windows

4 Interior model including rooms, stairs, windows, doors, furnishings...

CityGML LoDs

LoD2 cityGML model, fully

automated generation process.

Scalable procedure extensible to the

new pilot cities.

Building ID related to cadastral

reference further information can be

related to the model.

Accuracy related to the input DSM

information, increasing resolution

more accurate results can be

achieved.

containing a hierarchical

structure of buildings, sub-

objects (roofs, walls) and

geometry.

First requirement Open the Data

Not Only visualization

Building Energy performace

Several services on top of 3D

Noise pollution:• punctual noise value as acquired from

the crowd• averaged value as a noise map

Energetic values as:• Building roof solar potential• Facade energy dissipation• Energy performance simulation

Routing for diversely-able citizen

Realistic 3d city model

Second requirements data collection integration

Authoritative sources

Sensors

Crowd source

The OSM model is open and extensible with new tag, furthermore many features as stairs, sidewalks and crossing are contained into the database
