This book is based on a one year lecture course entitled Map Production delivered to undergraduate students of land surveying at the University of Nairobi. It is intended not only to help students and lecturers but to be retained as a reference manual by land surveyors during those phases of their careers when they may be engaged in map production. Although based on actual or recommended practice in Kenya it is hoped that it might be useful in other anglophone developing countries (most of which are situated in the tropics). Map producers comprise two main groups: in the first group are both official and commercial mapping agencies, who se main task is the production of new and revised basic topographical and cadastral mapping together with a limited amount of specialized mapping and mapping at small scales derived from the basic mapping. In the second group are specialized map publishers who use the national mapping as a base and edit it to suit their particular purposes. Their products include reference atlases, school atlas es , motoring maps, tourist guides, and various environmental studies. Such organizations usually have to be self-financing and their staff does not normally include surveyors. There are some differences between the two groups in training and objectives. Books on cartography have generally been written by and for the second group. This book is designed mainly for the first group although the greater part of it must be relevant to the work of all map producers. Basic map production begins with aerial photography, ground control surveys, computing, and photogrammetric plotting. This book do es not cover these stages but starts at the point where the raw material of maps (control point lists, survey field sheets, photogrammetric plots, computer tapes, etc.) is received in the cartographic office. The main stages that folIoware design, drawing, printing, automation, and records. Obviously many techniques contribute to map production, e.g. land survey, air survey, photogrammetry, computing, drawing, photography, printing, etc. On each of these and other relevant subjects many specialist textbooks and manuais have been published, which should be consulted by the reader requiring more details, always bearing in mind that there are frequent new developments in techniques, equipment, and materials; these are usually first described in professional or trade periodicals, conference reports or manufacturers publicity literature, all of which must be obtained and studied by any map producer who wants to keep his ideas up-to-date. In map production, the philosophy and technology are inextricably intertwined and it is both difficult and inconvenient to separate them, e.g. to describe the theory of hill shading in one part of the book and the technique of applying it in another. The various stages of map production are therefore dealt with as far as possible in the order in which they occur and both principles and practice are described at each stage. No specimen of a completed inap is included in this book. The reader is recommended to obtain a sheet of the standard 1 : 50000 topographical map current in his own country and keep it with the book for easy reference.
