Zoning Environmental Management Plan (ZEMP) in Angkor
The paper-based GIS system of archeology and monument protection was replaced by the one of the first digital solutions of the industry between 1992 and 1993.
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. Afterwards: „The Royal Angkor Foundation in Hungary in close cooperation with SOAS (London University, School of Oriental and African Studies) and NASA Jet Propulsion Laboratory has been working on world heritage sites, in general, and on Angkor (Cambodia), in particular, for a decade.
The Angkor GIS (AGIS) is an information system which helps professionals to get information about the Angkor Eco-site. It contains information from a wide area of interest to help see the facts about Angkor globally. Angkor GIS has been developed first by György & Annamária Csáki (1992-1993) for the 'Zoning and Environmental Management Plan' (ZEMP) for UNESCO to apply GIS technology on the archaeological sites in Angkor, Cambodia. AGIS-1 incorporated research achievements of numerous professional fields. It was also a well-applicable methodology of data acquisition, and provided analysis and proposed solutions for preparing a new nomination dossier at that time for Angkor. The new approach required new tools to be involved. The handling and analyzing of the huge quantities of data was not possible with traditional manner already 8 years ago. And, this was the point where the help of a computer had to be taken together with the dynamically developing new branch of informatics, the GIS."
You can see some of the drawings created as a result of our work, which can be compared with the current status in GoogleMap.
We had used an old coordinate system differing from the present time UTM zone 48N system. The shift between the present UTM coordinates and our Erda MapServer coordinates is dx = 395 m, dy = 334 m.
