Furthermore, the secretariat advised the African Remote Sensing Council and its subsidiary organs, and assisted in expanding the activities of the regional centres for training and user assistance. 42. As principal investigator on behalf of member States, the secretariat took part in technical verification of a new set of photographs from a metric camera payload using the services of RECTAS and RCSSMRS. The first batch of six stereo pairs of space photographs of two selected sites in Africa was forwarded to the European Space Agency working group responsible - 21 - for the experiment. A paper on African photogrammetry and resources inventorying was presented at the world conference of the International Society for Photogrammetry and Remote Sensing in Brazil. (e) Resources of the sea A3.
