Abstract
Introduction
The task of the National Land Survey of Sweden (NLS) is to
contribute to an efficient and sustainable use of Sweden's real
estate, land and water.
The establishing and managing of the Swedish Integrated Cadastral
System in Sweden has been a major task for NLS for about 30 years. The
system has been in operation for about 25 years and is subject to
continuous development.
The Digital Cadastral Index Map is now also included to the system.
The system also provides integrated information for multi-purpose
use in the whole Swedish society. The information is disseminated
on-line, direct to the users by NLS or as value added services by
information agents.
Integrated information together with the national cadaster index
map is accessible via Internet and available for more than 4 million
citizens.
National Cadastral Index Map
The Cadastral Index Map is a part of the Real Property Register and
gives the geographical representation of the property. The
responsibility for building and maintaining the digital map is on
shared responsibility bases between the national government
authorities and 39 municipal authorities (out of totally 290
municipalities).
Last year an agreement between National Land Survey and these 39
municipalities however was made concerning deeper co-operation. The
main goal out of the agreement is to build a National Cadastral Index
Map (NDRK) covering the whole country.
NDRK shall:
- be the base for all geographic databases, which present property
information
- be available for organisations and the public via Internet or
via certain data format
- be stored in a system run by NLS
- be updated by the source of information
- handle objects with unique identifiers, which are joint with the
Real Property Register
- receive and disseminate changes via an User Interface
- be completed before the end of year 2003
User Interface 2000
The User Interface 2000 (UI 2000) is developed in a project and
composed as a concept for interchange of geographical information
between first of all the National Land Survey and the Municipalities.
The UI 2000 consists of information models, descriptions of
transferring mechanism and how they will be administrated and
maintained. The interface is not a format or software but a series of
technical principles, which can be used for different formats and
different data systems.
UI 2000 consists besides models of information, of specified file
format and an application for data transmission. These three parts are
independent of each other and are possible to change and further
develop separately.
Internet
NLS has launched new Internet service View and buy maps and
detailed aerial photos of all of Sweden. It is an e-commerce site
where visitors can view and buy aerial photos and maps and search for
individual properties
www.lantmateriet.se
provides two services especially designed for estate agents and banks,
etc. These services are called 'FastighetsSök' [property search] and
'KartSök' [map search], and enable users to obtain information on the
owners, tax value, addresses, etc. of a particular property by giving
an address or clicking on a map
