In addition, the Authority is responsible for surveying and mapping for all other civil or military agencies.
The development of the Authority is technically related to three foreign co-operation projects:
+ A British project, from the beginning 70s to the end of the 80s, completed aerial photography and map coverage of the country at scale 1:60,000 for black & white photographs, and 1:50,000 for maps in English or Arabic from which smaller scale maps have been drawn (see indices in product section).
+ A Swiss project in the 80s created a photo lab and a photogrammetric section in the Authority. In addition, all the Authority's photographs were indexed and a two-sheet map of Yemen at scale 1:500,000 was prepared.
+ Two French projects in the 90s respectively dealt with nation-wide geodetic and levelling network, and modernisation of the agency in the area of digital photogrammetry and mapping.
