trends can be expressed in the following terms: multiple uses, automa-
tion, geocodes and digitization.
The cadastre and the land register were each originally designed
for one purpose: taxation and security in rights. But almost from the
very start, the information provided and the maps produced were
found to be very useful for other purposes as well. Only during recent
decades, however, this point has been stressed
in the technical design
of cadastres and land register.
Modern society has developed into an information society, which
both requires, and has the ability to produce accurate information.
However, if the information is to be convenient to handle, it must be
linked to identifiable spatial units. The cadastral
land unit is one such
unit which is a suitable basis for much information – not only con-
cerning the land itself, but also the people living on the land and many
of their activities.
This does not, however, mean that cadastre/land register them-
selves should contain the necessary land information. On the contrary,
all experience shows that both cadastres and
land registers should be
kept simple, and concentrated only on the data required for their par-
ticular purposes. The essential thing is the uniquely defined land unit,
which can be used as a key for integrating many different records,
thus making available a vast amount of relevant land information.
It is, however, difficult to achieve such
a high level of integration
when all records are kept manually. Two records such as a cadastre
and a land register could certainly be made to influence each other
considerably, and to function as one source of information. But in or-
der to advance
from here to an efficient, fully integrated system con-
sisting of several different sub-systems, automation is essential.
