ABSTRACT:
The first phase of research and development of tools for establishment of the digital cadastre of real estates in the Czech
Republic has been finished. It was a part of problems solution of the Information System of Surveying, Mapping and
Cadastre as one of the National Information System of the Czech Republic source registers.
The solution was oriented above all to areas of the geodetic control and the cadastre of real estates digitization. The solution
results mainly gave technical (hardware and software) and technological tools for creation, management and utilization of
the Survey Information File, so as the Descriptive Information File of the cadastre of real estates (digital cadastral map)
database. Possibilities of photogrammetric methods application were solved too.
1. INTRODUCTION
The first phase of research and development of establish-
ment of the digital cadastre of real estates (Czech abbr. KN -
as used further) has been finished. In the period 1991-1995
the solution was realized by the Research Institute of Geod-
esy, Topography and Cartography (Czech abbr. VUGTK) i in
cooperation with departments of technical development
in cadastral offices (Czech abbr. KU), and also with the
Land Survey Office (Czech abbr. ZU) in Prague. The solu-
tion was passing as a part of the state development program
"INFORMATIZACE" (English meaning INFORMATION
PROCESS) according to decree of the CR government No.
124 dated 17.4.1991 in the form of research and devel-
opment project "Establishment of the Automated Infor-
mation System of Geodesy and Cartography" (Czech abbr.
AISGK). The conception of the AISGK solution which will
be introduced in operational practice under the name
INFORMATION SYSTEM OF SURVEYING,
MAPPING AND CADASTRE (Czech abbr. ISZK)
(in accordance with the Act No. 359/1992 Coll.) determined
the basic prerequisite: ISZK should become one of source
registers (information systems) of the National Information
System of the Czech Republic (Czech abbr. SIS CR). It is
urgently needed e.g. for building Geographical Information
Systems (GIS).
There were reached basic targets of the project solution in
techniques (hardware - HW, software - SW), technologies,
organization, legislation, and economics. Due to the CR gov-
ernment care and merit of the Czech Office for Surveying,
Mapping and Cadastre (Czech abbr. CÜZK) the results are
being realized in operational practice [1].
2. ESSENTIAL SOLUTION RESULTS
Results of the project solution have created the basic pre-
requisities namely for:
— applying the surveying and especially cadastre infor-
mation as one of the SIS CR source registers,
— enforcing the integrity of arising databases in the ISZK
frame,
— conversion of the CR geodetic control into the Euro-
pean Terrestrial Reference Frame (ETRF),
— renewal of the cadastre of real estates with its recovery
of legal relations, and with its conversion into digital
form including tools for the Digital Cadastral Map
(Czech abbr. DKM) creation and maintenance.
2.1 Current imagination of the SIS CR model
The current version of the SIS CR model represents the
basic internal and external data flows in two levels - the
central and the local ones. To basic data models (data
structures stored in selected registers), the common
characteristic of them is general respecting the GIS
technology, belong [2]:
— Register of Inhabitants (Czech abbr. ROB), the main
identifier of which in the CR is the uniform series of
personal identification numbers. It ensures the uniform
identification of citizens.
— Register of Organizations (Czech abbr. ROR), the main
identifier of which in the CR is the uniform series of
identification numbers of organizations with enterprising
character (Czech abbr. ICO). It ensures the uniform
identification of both juridical bodies and physical bodies -
entrepreneurs (business undertakers).
— Register of Spatial Identification (Czech abbr. ÜIR), the
main identifier of which in the CR is the uniform series of
space unit numbers on the territory of the CR as well as the
uniform series of building numbers (so called "describing
numbers") in regions. It ensures the basic division of the
state territory into administration units as well as fulfils
function of the Register of Buildings in regions.
