The main lessons from a technical comparison of European
cadastral systems
Recently European Union has conducted a comparison of Euro-
pean cadastres. The three main technical conclusions
of the studies of
urban cadastres are: (1) many European countries are moving toward
the integration of the cadastre with the property registry, (2) existing
graphic and textual information is detailed
but their homogeneity var-
ies from one country to another and (3) computerized technology is
new commonly used.
Historically, ownership was established without cadastre. Never-
theless, nowadays, most European countries have understood the im-
portance of linking the property registries
or mortgage books with the
cadastre to eventually achieve a legal cadastre or a parcel based regis-
try. In the land registry, the right is created once inscribed in the book
under the control of a judge. The inscription
in the land book is ac-
companied by an accurate survey. In the mortgage book, the right is
created by the contract between the parties. The inscription in the
mortgage book makes the right defendable to a third party. It is now
compulsory to ensure the exact correspondence between the cadastre
and the mortgage book.
In most countries the cadastre is old and homogeneous.
Urban ca-
dastre maps cover the dense of urban and dense of peri-urban areas of
main European cities. The cartographic and historic homogeneity of
these maps is highly various from one country to another. Moreover,
the characteristics of the textual information associated to the graphic
information vary largely from one country to another.
Computerized technology is now commonly used. Most of the
countries have almost finished capturing cadastral
textual information
and are now on the way to digitize the graphic information (cadastral
maps). Technical departments are now equipped with highly sophisti-
cated computerized equipment for data acquisition and maintenance.
