Abstract
Though many organizations have been studying or emphasizing the need for a standard set of map symbols for large scale maps (1:240 to 1:4800), little to date has been done to develop a standardized legend. The main problems associated with producing a standard legend are, providing a unique symbol for each feature, making computer programing of the symbols possible, implementing the standard once it is adopted, and maintaining the standard. These problems and their solutions are addressed. The actual set of symbols and their development are presented in Chapter V of the forthcoming manual, Manual on Map Uses, Scales, and Accuracies for Engineering and Associated Purposes. This manual is being prepared by the Committee on Cartographic Surveying, of the Surveying and Mapping Division, ASCE.
