• To assure unique identiication of each property unit
• To assure that each property unit's description includes a digital graphical plan
• To assure its dissemination and usage by general state administration—subject
though to specific permissions and protocols
• To assure both citizens and companies general access to the system—again,
subject to specific permissions and protocols.
Because cadastral surveying has been taking so long to cover the whole country,
what has actually been happening since the middle 1970s is that several private
construction companies and state agencies directly intervening in territorial opera-
tions have technically undertaken themselves cadastral surveys as needs arise. In
particular, local municipal authorities are in possession of virtually all construction
plans within their territorial jurisdiction.
The facts above led to a further central government's decision, formalised by
Cabinet Resolution nr. 56/2012 (PCM
2012
). While formal cadastral surveys are
being carried out in the field, a nationwide repository of geospatial data currently
owned by both public and private sectors shall be set up (PCM
2012
):
• To be processed and checked against cadastral standards towards its eventual
official approval
