摘要：Rapid advancement of computer technology has opened wide possibilities for co mmunication and networking over the World. Many universities and companies in Africa have already introduced the Internet as a basic tool for communication and transfer of information on the new technologies. It has great educate and informative aspects, specially in view of poor availability of new professional books and journals and limited access to professional international conferences in Africa. Geo- information data are very useful for planning and execution of various engineering and environmental projects and therefore in some of African countries GIS technology has been introduced on different levels, usually as the pilot projects with involvement of external experts and funds. However, the main common problem is lack of up-to-date geometric digital geo-referenced information on terrain which is required as a frame for various thematic data. The graphical topographic maps and cadastral plans are not complete, out of data, and they often do not fulfil the required accuracy. The old fashion analogous instruments and methods, which are still used in most of African countries, can not satisfy the requirements for digital information which is requested from photogrammetry. Transfer of new digital technologies for mapping is very limited in Africa. This is not only because of financial restrictio ns but also because of organisational and managerial problems and sometimes negative approach for their implementation. The author who worked at the universities in Southern Africa countries, Zambia and Zimbabwe, from 1984 to 1999 and after 15 years returned back to Europe, will discuss potentials, possibilities and restrictions for implementation of digital mapping technologies in Africa
