Abstract
The Global Positioning System (GPS) is rapidly becoming an important tool in the surveying community. It is currently being used in a number of applications, ranging from cadastral control point establishment to hydrographic surveying. The emphasis of this paper is on the contribution of GPS to the information society. Fundamental aspects of GPS are presented and the current status of the system is outlined. The advantages of using GPS in the collection of georeferenced data and specifically its impact on Geographic Information Systems are described. Issues such as the establishment of an Active Control System, the development of new surveying techniques and the integration of GPS with other sensors for cost-effective data gathering are addressed. The future role of GPS in the collection of georeferenced information and a discussion of new and exciting opportunities for surveyors being created by GPS, concludes the paper.
