1:50,000 topographic mapping of Nigeria : progress report 31/12/62 - 31/12/65

Abstract

The period Dec 1962-Dec 1965 has shown considerable progress, arising not only from a greater emphasis on topo—mapping on the part of the Nigerian Survey Departments but also from the technical assistance received from the governments of Canada and the United Kingdom.The mapping has been done by a private firm under contract to the Canadian Government while for the United Kingdom the mapping has been carried out by a government department.
