Nowadays, Czech Office for Surveying, Mapping and Cadastre (COSMC) operates with Software
system for data creation and actualization (MicroGEOS Nautil) in terms of Real estate cadastre (RC)
information system (ISKN) for automated real estate cadastre actualization all over Czech Republic
(CR) territory.
The CR automated cadastre development started in 1997, and VUGTK was the project team leader.
The CR automated cadastre first release was put in operation in 2001. The technical and
methodological support is provided by VUGTK, considering changes in legislation and customer
requirements.
The “Ness Technologies” were engaged on the last stage of the automated cadastre creation project
in terms of infrastructure equipment design and implementation.
During the realization of automated cadastre VUGTK created:
 Database (DB) for real estate cadastre update;
 Graphical user interfaces;
 Cadastre and geodetic information processing subsystem;
 Methodology and tools for work with legislation base.
Tools for work with legislation are intended to solve two top-priority tasks:
 Business processes description and business rules assignment according to which the property
laws registration and other legal operations are processed in the system;
 Business processes and business rules actualization in case of legislation changes in the fields
regulating real estate cadastre carrying out procedures (on receiving official request from
COSMC).
The “Ness Technologies” task was to create infrastructure computing environment, consisting of
next components:
 Infrastructure equipment;
 Information security;
 Applications installation
As a result, “MicroGEOS Nautil” and “DIKAT” software complexes were developed and put in
operation. MicroGEOS Nautil software complex is intended for cadastre information input and
processing by COSMC divisions, DIKAT – for cadastre information (topographic plans etc.) input
and processing by COSMC divisions and private survey companies.
The MicroGEOS and DIKAT software complexes technical support and modernization is provided
by VUGTK.
Customer (COSMC) decided to unify and modernize two main automated cadastre software
components – MicroGEOS Nautil and DIKAT – in the process of systems’ operation, according to
the modern practices and new customer requirements. The next projects were initialized to operate
the tasks above:
1. Cadastral system for cadastral documentation creation and update – MicroGEOS Nautil
(2005 – 2008).
Executive: VUGTK.
Name of contract: Development of tools for renovation of cadastral documentation in frame of
graphic information file in relation to development of information system of cadastre of real
estates.
Name of Purchaser: Czech Office for Surveying, Mapping and Cadastre.
рус. Чешское управление землеизмерительное и кадастровое (ЧУЗК).
The system operates as application in ORACLE 9i environment with Client-Server network
architecture usage and is accessible for all 121 Cadastre Offices of Czech Republic simultaneous
work.
Main system advantages:
 Unified application for all 121 Cadastre Offices of Czech Republic;
 Unified HelpDesk system for system’s technical support;
 Unified cadastral documentation for all CR;
 Unified education system for Cadastre offices’ staff, working with the system, in VUGTK.
Real estate cadastre database stores information about lands. Lands’ geometric plans are stored
in database, which include lands’ coordinates and topological attitude. Information about property
rights on lands and real estate are also stored in database. Database stores records about real estate
subjects, rights on lands, limits, lands description and other rights and technical information.
Real estate cadastre database is centralized unified database of governmental level.
Graphical user interface subsystem supports procedures of visualization, editing, lands
combining, lands borders joining, imposition and other operations with lands’ geometry.
Cadastre and geodetic information processing subsystem supports solving tasks of geometrical data
preprocessing, particularly:
 Cadastral survey data acceptation, verification and input to the system;
 Primary observation data computing and processing, including field survey data, GPS data,
theodolite traverses, triangulation data etc.;
 Control points database support.
cadastral data update (actualization) is executed on the base of topographical (geometrical) plans,
new mappings, organization of the use of land, old cadastral maps and surveys, made by private
survey companies, digitization,
The software system consists of two subsystems – subsystem for work with database and graphical
subsystem.
Database work subsystem provides next main functions:
 Projects carrying out on demand of COSMC system users;
 COSMC system’s information system users’ records carrying out;
 Plan control points database carrying out;
 Graphical data storage;
 Old and new plots comparison;
 System security and control.
Graphical subsystem provides next main functions:
 Geodetic information files processing and carrying out;
 Graphical data actualization in system’s database.
Migration to the “virtual” physical servers on the Microsoft Hyper – V platform is being realized
now.
The system operates in COSMC system independent computing network, dedicated all over CR, to
which all Cadastral Office servers are included. External users do not have any access to the
network. But external users can easily browse cadastral data in the Internet. This function is
supported by “Ness Technologies” Czech office. Separate database replication server is used to data
announcement in the Internet.
2. Development of Procedures and Methodologies in Renovation of the Cadastral
Documentation, in Survey Sketches Creation and in Cooperation between Cadastral Offices
and Surveyors. (2004 – 2009)
Executive: VUGTK.
Name of contract: Development of Procedures and Methodologies in Renovation of the
Cadastral Documentation, in Survey Sketches Creation and in Cooperation between Cadastral
Offices and Surveyors.
Name of Purchaser: Czech Office for Surveying, Mapping and Cadastre.
рус. Чешское управление землеизмерительное и кадастровое (ЧУЗК).
“DIKAT” («Digitální katastr») software system is intended to the changed objects (cadastre survey)
detailed measurement processing. The system operates with the relevant cadastre survey data for
changes establishment in all 121 Cadastre offices of CR. The system makes all necessary operations
to create plans automatically, with plot areas, plot comparison and area definition with new soil
quality of locality. “DIKAT” also includes tools for survey notes processing and geodetic tasks
solution based on digital cadastral maps, layout drawing creation etc.
The software system consists of two subsystems too – subsystem to work with database and
graphical subsystem.
Database work subsystem provides next main functions:
 Database creation and administration;
 Data input to the database from huge amount of cadastral territories;
 Plan control points database administration;
 Plot plans design;
 Plots and plots’ parts relative comparison;
 Users and cadastral projects administration.
Graphical subsystem provides next main functions:
 Plans’ sketching and editing;
 Points’ representation and editing;
 Points’ numbers list creation;
 Soil quality of locality automated calculation;
 plots’ numbers change;
 Graphical part and database control;
 Plans’ prining.
The system operates in the COSMC system independent computing network too.
