REPORT OF COMMISSION VII 
GVII-43 
team consisting of an ecologist and a geologist spent three months in the field, 
visiting all parts of Jordan. Their field work will provide a key for the mapping 
of vegetation units. Jordan will, therefore, be supplied with vegetation maps 
based on mosaics constructed from the aerial photographs; these will form the 
necessary basis for a pasture improvement program. 
Irrigation surveys use aerial photos: In Pakistan aerial photos are finding ex 
tensive use in irrigation projects. In Bengal aerial photos of 1:40,000 scale 
covering 15,424 square miles were used in planning. Table stereoscopes were 
used. Another area of 3,200 square miles in East Bengal used 1:40,000 scale 
photos. Photos were interpreted using mirror stereoscopes. On another project 
231 square miles was interpreted using 1:30,000 photos. Plans for another irriga 
tion scheme used 1:30,000 photos covering 390 square miles for the Kurramyarki 
Irrigation Project. Maps were made of all these projects by the radial line 
technique.
