The Survey of Kenya, with headquarters in Nairobi, was involved in field mapping alongside the Directorate of Overseas Surveys and Directorate of Colonial Surveys during British colonial rule and remains the main centre of geospatial information in Kenya.
The Survey maintains the air photography, maps, cadastrals and geospatial data of Kenya and is an important component to improving land ownership and jurisdictional boundaries in the country. These are critical functions toward political goals in the Ministry of Land, Housing & Urban Development. The Survey is rapidly expanding with new infrastructure, an institute for training personnel, and new developments. Some infrastructure was a legacy of the colonial administration and was shown to some REAL members and Dr. Martin Skrydstrup during a visit in May, 2014.
Some details about what is available can be found here.
Here are some photos of a Wild Heerbrugg model A8, an analogue photogrammetric instrument, used to view air photos and draw contours and features for map printing. This model was phased into the market in 1952 and was available until 1980 (Hughes et al., no date).
