The GIS is designed to handle general as well as detailed data of the location, area, and legal status of all historical sites in Egypt in a clear, simplified form. It allows for storing, integrating and analyzing data at different scales and on different backgrounds, and makes it possible to include several levels of information, such as site boundaries, buffer zones, and urban and agricultural areas.

The GIS Center's mapping system deals with two main data categories: site location data and background data.

Site Location Data

The Amlaak (Property and Survey) departments of the SCA are the main source of official site location data. Other governmental institutions, international organizations, archaeological missions, and books provide supporting data. The Amlaak data is the basis of the system; the other sources are used to verify, update, and expand upon information. The system also uses other data sources, such as GPS points, to add to the scope of information available.

Background Data

Background maps form an important component of the system. Primarily obtained from governmental sources, these maps are used to provide a context for GIS analysis and are of several types: raster or vector, topographical or cadastral, as well as satellite images.

Background maps present information on changes in land use around cultural heritage sites and can be combined to assist in different kinds of analysis. Site boundaries, for example, are superimposed on the latest cadastral maps to provide information for site protection and land use planning.
