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. For the biennium 1984-1985 resources of the sea is a subprogramme of the natural resources in Africa programme but the only resources available are one and a half months' consultancy and $ 5,0C0 provided for travel on missions.

analysis: The text appears to focus on the activities and programs of an organization related to natural resources, specifically in the context of Africa. The mention of aerial surveys, photogrammetry, and marine resources suggests a strong connection to natural resources and the environment. Additionally, the text touches on science and technology, which is also a relevant category.
