Engineering activities and development plans rely chiefly on the availability of precise spatial data, which in turn depends on the accessibility of an accurate Geodetic Data Infrastructure (GDI) as reference frames for all geospatial measurements. A GDI is considered a key component in the undergoing National Spatial Data Infrastructure (NSDI) for Egypt. The current study proposes a structure of a GDI in Egypt that has multi-discipline utilizations and aims to develop an integrated database combining several types of geodetic datasets within a Geographic Information Systems (GIS) environment. The study develops such a GDI for the Nile delta region, as a case study, containing the available heterogeneous geodetic datasets. The problems and advantages of such a GDI are thoroughly investigated herein. Accordingly, some recommendations are presented, too, for constructing an integrated GDI over a national scale in Egypt.
