Due to the radar technology used, 3DCity offers
different advantages over the traditional methods. In
particular, the monitoring is fully remote, without the
need to access to the building. In fact, the
morphological characteristics of the buildings allow
to use particular points already on the structure that

The advanced data processing techniques used by
Aresys allow to extract only the significant points,
obtaining a result that is more accurate and without

The maximum accuracy reached is 0.1 millimeter.
The area observed depends on the distance
between the instrument and the building (e.g. from a
distance of 20 meter the area monitored is 200
square meter detecting about 4,000 points).
