“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
![Page 4: 3D enabling Smart Cities](https://reader038.fdocuments.in/reader038/viewer/2022103017/557cff57d8b42a98158b506d/html5/thumbnails/4.jpg)
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

3D City Information
![Page 9: 3D enabling Smart Cities](https://reader038.fdocuments.in/reader038/viewer/2022103017/557cff57d8b42a98158b506d/html5/thumbnails/9.jpg)
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

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.

Medium Client;
CityGML geometries parsing
to build a data structure
containing a hierarchical
structure of buildings, sub-
objects (roofs, walls) and
geometry.
Renderable geometry
generation from cityGML on
server side;

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
