GDiS geodetic information system for SUDOP PRAHA

SUDOP PRAHA a.s. implemented a GDiS system that significantly saves time and increases work efficiency when completing tasks related to the administration of proprietary relations for land affected by construction. The system keeps up-to-date information about lots and owners affected by the construction planning project. ​




“GDiS system brings a totally new approach to data processing and enables us to hold our leading position in the area of design and engineering of traffic constructions.”

Ing. Roman Čítek,
Centre of Engineering and Geodesy Manager



  • Increase in work efficiency when processing the construction proprietary rights administration
  • Automation of the record keeping process regarding land owners affected by the construction
  • Up to 200% faster processing of results, plus higher quality analyses processing
  • Significant simplification of work due to clear and up-to-date information about communication with the land-owners
  • Ability to react to changes in the Cadastre of Real Estate while the project is still running


Customer profile

SUDOP PRAHA is a design, consultancy, and engineering company specializing in comprehensive solutions for transport infrastructure, specifically railway construction, road and highway construction and urban transport systems.

Starting point

Administration of the records of land-owners affected by the construction was managed in separate MS Excel files. Engineers had to manually search for the data needed in the Cadastre of Real Estate (CRE) maps, updating the information was very complicated and any potential changes had to be laboriously searched for.

Project outcome

The outcome of the project is a system that contains the history of the data from the Cadastre of Real Estate and building documentation, including partial communication with the owners. The system reacts flexibly to changes in the CRE, as well as to the changes in the building project itself.

our Solution


An information system was designed where data from the Cadastre of Real Estate and areas affected by the construction are automatically processed and compared against each other. The results serve as the basis for geoanalyses and generation of reports of the affected owners.

Relevant CRE data for each project is stored in unified, chronological data storage in the GDiS system database. The chronological storage makes it possible to search for the CRE status for the given date when the communication with the owners took place and to automatically detect and display any changes happening with the particular immovable property that require new communication with the land-owners. It is possible to import the CRE data into the system from VFK and DGN formats.

A client environment in Bentley (MicroStation, Bentley Map PowerView) was developed within the information system, where it is possible to define the area affected by the construction on a cadastral map background. Attributes can be assigned to an area allowing effective sorting of areas into groups, such as permanent occupation, temporary occupation, location of an easement, etc. These defined areas are also sent from the client and stored in the central storage, and the system compares them with the CRE data. Based on these intersections, a list of affected immovable property and people is created, for which it is possible to define other data, such as date of purchase, future owner, and date and means of communication with the owners.

According to these attributes, as well as according to the information about the immovable property from the Cadastre of Real Estate, it is possible to search for the lots in the graphics or to generate reports in XLS format. Additionally, all user data recorded for each immovable property and owners are tracked and different colours can mark all changes happening to the relevant construction area or the CRE data.
