ABSTRACT |
The history of Surveying in Nigeria is briefly outlined. The historical development of Aerial
Photography and Photogrammetric Mapping in Nigeria is reviewed. The roles of Federal Surveys
and private mapping companies in Photogrammetric operations are examined. Local problems
that the Photogrammetrist faces in Nigeria are briefly highlighted. Finally, a future projection of
the role of Photogrammetry in the coming decades is made.
INTRODUCTION
Photogrammetry has played a very important role in the production of maps in Nigeria.
Due to its obvious advantages as a fast, economic and more efficient mapping tool, Photogra-
mmetry has been used for the compilation of topographical maps ever since serious mapping
started in Nigeria in the late 1950s. The first topographical maps were compliled from high
altitude aerial photographs taken by the Royal Air Force. Photogrammetric instrumentation
at that time was rudimentary and consisted mainly of direct projection instruments of the
Multiplex series. |

Today, photogrammetry has grown into a very sophisticated science. Modern first order
plotters are now available in the country. Furthermore, several qualified professionals are also
available. This paper traces the history. of Aerial Photography and Photogramm etric Mapping .

2.0 BRIEF HISTORY OF SURVEYING IN NIGERIA
The history of Surveying in Nigeria began with the establishment of a Survey Department
in Nigeria in the later half of the 19th century. The surveyors in those early days were mainly
British Army personnel attached to the Colonial Office. The sole purpose of those early surveys
was to provide maps for the smooth operation of the colonial administration. As the survey
operation expanded, the need to train indegneous surveyors arose. Consequently a Survey
School offering a 3 year basic survey course was established in Oyo in 1908. The graduates of the
School at Oyo joined the colonial Surveyors of the Survey Department in the initial surveys
which were mainly acquisitions and demarcations of the administrative headquarters at Lagos
Calabar, Lokoja and so on. When Nigeria became a federation in 1954, Regional Survey
Departments were created at Ibadan, Enugu and Kaduna with a Federal Survey Department
based in Lagos. The Federal Survey Department was given the responsibility for National
Framework Survey including primary traiangulation and levelling, surveys of national impor-
tance such as international boundary surveys and aerial Photography. The survey divisions
in the Eastern Region, Western Region and the Northern Region were to be responsible for
Cadastral Surveys and Large Scale Township Mapping within their boundaries.
