Planning and Engineering Considerations for the Official Map

This paper deals with two distinct yet closely interrelated problems. The first of these problems is that of how to make the official map of the city a truly useful and effective plan implementation device. It is a problem to which planners have generally given little attention. Consequently, a potentially powerful planning tool has been either ineffectively applied, or entirely neglected. The second of these problems, closely related to the first, is that of economically providing an adequate system of horizontal control in urban areas. Such a system can serve as both the basis for the compilation of accurate maps and the execution of all necessary survey work. Because of the great amount of mapping being undertaken in urban areas, particularly by aerial survey methods, this problem should be of great concern.
