Documentation, using GIS techniques in conservation of a World Heritage Site, a case study of "The Old City of Jerusalem"

Abstract. Architectural Heritage is a strong witness to a people's history that symbolizes their identity. The Old city of Jerusalem, and as a UNESCO world heritage site 1 is a living city especially with its great wealth of historic structures, including places of worships for the three monotheistic religions, significant monuments, and whole historical residential neighbourhoods, Figure 1.

In spite of the prevailing political conditions, difficulties that Palestinians encounter in Jerusalem, and the demands of the modern life and ever-growing population, several attempts had been stimulated to protect this Heritage. A specialized program (Old City of Jerusalem Revitalization Program – OCJRP) has been working since 1994. The program was established by the Welfare Association2 to help protect Jerusalem's cultural heritage applying international conventions and the highest professional standards for the direct benefit of residents, building users and visitors to the Old City as well as for future generations.

This paper aims to describe the various activities and main findings carried out by the Technical Office of OCJRP – in the last twenty years as well as stressing on problems encountered by the team. It will rely on the team experience accumulated during the implementation of the projects, the research, surveys and studies undertaken by the team who helped in the creation of the database and its ongoing process.
