— Measuring the movement of breakwater blocks, using ship—mounted 
cameras. 
Both the University of Cape Town and the University of Natal are assisting 
with the recording of archaeological and historical items and sites. In 
particular a wealth of fast—deteriorating cave paintings and rock engravings 
of the Bushmen are being captured for posterity under the direction of Pro— 
fessor D.A. Scogings. (Ref. 2). 
Several universities and individuals are conducting research into close—range 
and terrestrial photogrammetry. The following are examples of this acti— 
vity:— 
University of Cape Town — (Prof. L.P. Adams) — Measurement of sea 
waves in the surf zones; measurement of floating buoys to determine 
close—shore sea currents; 
University of the Witwatersrand — (Mr. R.F. Rawiel) — Use of photogram— 
metry in orthodontics; t 
University of Fort Hare — (Prof. K.N. Greggor) — Reconstruction of the 
positions of vanished historical locations from old photographs; 
Council for Scientific & Industrial Research — Measurement of convolu— 
tions in the human brain; ballistic measurement, etc.

In South Africa, photogrammetry continues to be regarded as part of the 
surveying discipline. One or two—year courses are included in the curricula 
of surveying degrees offered by a number of universities. Some photo— 
grammetric teaching is also provided for civil engineering and allied fields. 
Post—graduate work in photogrammetry may be undertaken at the Universi— 
ties of Cape Town, Natal, Pretoria and Witwatersrand. Technician courses in 
photogrammetry are provided at some of the Colleges of Advanced Technical 
Education and some in—house training is undertaken by a number of the air 
survey companies for their own operators.
