The Dutch
Cadastre has worked several years on the development of an object-oriented
topographical database at the scale 1:10,000, called TOP10NL. The underlying
data model is based on the general Dutch standard for data models: Basic Model
for Geo-Information (NEN3610, 2005). This general model is based on the
international standards of ISO and OGC. Other geo-information sectors are also
recommended to use the general model, so the data can be exchanged between the
different applications. The sectors of physical planning, water management, cultural heritage and
archaeology already adopted this general model. The chosen exchange format is GML.
In the
public administration area in the Netherlands the idea has developed to create
Basic Registers. Basic registers are those administrations which are essential
for the public sector. After several years of preparation the Dutch government
has defined 6 basic registers which will be established the coming years. The
registers are both from the geo-information field as the non- geo-information
field. The first 6 registers are:
Register of Persons, Cadastral Registers, Register of
Companies, Register of Addresses, Register of Buildings and Base map 1:10.000
(Topography) . Later other registers
will follow. The most appropriate public agency for the type of data in
question will be responsible for the administration. The Dutch Cadastre is
responsible for the registers cadastral parcels and topography. The
municipalities will be responsible for the registers of natural persons, addresses and buildings. The
Chambers of Commerce are responsible for the register of companies.
TOP10NL is
foreseen as the Basic Register Topography and acts as a base for the
National Spatial Data Infrastructure. With the introduction of TOP10NL a
large number of technical and substantive renewals are realised in the field of
topographical data. It is one of the first object-oriented topographical
databases in Europe .
The
new status of TOP10NL as basic register charges this with special requirements.
The use of the data will be mandatory throughout the entire government sector,
as there are several ministries, provinces, municipalities and water boards.
Also the users have obligations. They have to report back when they find errors
in the dataset.
This
paper reports about the realisation of the TOP10NL database, the principles of
the basic registers and the consequences for the organisation of updating and
delivery of the data to the users.
