The Geographic Information Systems Section of the Department of Spatial Information Systems of the Saudi Geological Survey (Fig. 2) undertakes technical tasks, serving all of the different specialized fields of geology. The Department comprises different units: the Digital Mapping Unit, the Spatial Databases Unit, and the Spatial Applications Unit, all of which contributes to the GIS needs and requirements of technical projects under the SGS framework and interests in geology, engineering geology, environmental geology, marine geology, and other geoscience fields. The technical and scientific staff of the Department possess geological and engineering expertise and formal academic degrees. Equally important, the Department is equipped with updated high-tech systems and devices, which contribute in meeting the increasing demands on GIS services within and outside of the SGS. These devices and the systems are maintained to keep up with the major developments in software development and data processing.
