About us

Founded in February 2000, Erda Kft. (Ltd.) is wholly owned by Hungarian individuals. Its predecessor Erda Bt., founded in 1992, ceased its operation after the registration of Erda Kft.

The following is a sample of Erda's body of work. If you are interested in a project which does not appear here, please contact our office for further information.


The users claim according to, various GIS evaluation systems

  • Government GIS systems
  • Public utilities GIS systems
  • industrial GIS systems
  • The users claim according to, special maps' doings
  • Digitizing
  • Various architectural photogrammetric projects
  • GIS database for archaeological findings

Erda's profile is highly varied. We have developed several GIS systems for city and town councils as well as for public utilities companies. In the meantime we have been maintaining the Hungarian MS-DAT system (Digital Base Map system). As a subcontractor are working in the Hungarian National Cadastral Project. Besides focusing on geodetic-photogrammetric and GIS developments, it is engaged in related scientific and artistic activities including archaeological research and documentation as well as photography and sound-recording.

The company is dedicated to acquiring and applying new technologies. Consequently, the new concept of Heritage Management is close to our heart. Since its formation, ERDA has been supporting and sponsoring archaeological research including the excavations of Municipium Achium Salla, a Roman town at Zalalövo (southwest Hungary), the excavations of a Roman imperial villa at Sanpotito, Italy and those of noble tombs of Djehutymes TT32 and Nefermenu TT184 , in Thebes, Egypt. ERDA surveyed the ceiling of the sarcophagus chamber of pharaoh Sethi I and the rock wall behind the mortuary temple of Queen Hatshepsut.


Our former tasks:

  • 1992-95: Designing a GIS system and a pilot database running on MicroStation platform for a research project called Reed classification of Lake Balaton and Lake Velence managed by KDT VIZIG (the Central Transdanubian Water Directorate).

  • 1993: Developing a MicroStation-based GIS database for archaeological findings of the Győr ring road section of the M1 motorway for Xantus János Múzeum, Győr.

  • 1992-93: Within the framework of a Zoning Environmental Management Plan (ZEMP) project our colleagues prepared the first MicroStation-based GIS system of the ANGKOR National Park commissioned by the UNESCO and the Royal ANGKOR Foundation.

  • As a sub-contractor of Erda participated in various architectural photogrammetric projects, including the survey of the building of the Hungarian Academy of Music (1996) and that of the Körösi Villa in Budapest (1998). The latter project was awarded the Budapest Architecture Award Medal in 1999.

  • 1998 to date: Erda has been developing analytical photogrammetry-related programs and organizing courses for Eurosense Ltd.

  • 1999 Developed and put into operation an analytical terrestrial photogrammetric system for Mátrai Erőmű Rt. (the Mátra Power Station Plc.) to monitor open casts.

  • As a sub-contractor of Geodézia Rt., Erda participated in the preparation of digital maps of several cities and towns in Hungary (e.g. those of Székesfehérvár and Nyíregyháza). The digital maps and the related Digital Base Map (DAT) data exchange format were realized in accordance with the Digital Base Map regulations within the framework of the Hungarian National Cadastral Programme. After taking it over from Geodézia Rt. in the middle of 1999, Erda has been developing and trading in MS-DAT GIS system, developed especially for the above project.

  • Recently Erda has been developed a new GIS system, which is being marketed under the name ErdaGIS. The product is a framework system running under MS Windows and Bentley MicroStation or GeoOutlook platform with an access to ODBC database. The user can customize it to meet the various requirements of tasks such as those of cadastral local government and public utilities systems. The program is wholly developed and owned by Erda. The new application was presented to the public at Hungarian Bentley Forum in October, 2000.
