Windhoek declaration on an African geodetic reference frame (AFREF) : outcome of the workshop on AFREF

Abstract

A uniform coordinate reference system is fundamental to any development project, application, service or product that requires some form of geo-referencing. All countries in the world have established some form of geodetic reference systems that are used for national surveying, mapping, photogrammetry, remote sensing, Geographical Information Systems (GIS), development programs, and hazard mitigation (earthquake studies, fault motion, volcano monitoring, severe storms, etc.).
