Though many organizations have been studying the need for or emphasizing the need for a standard set of map symbols for large scale maps 1240 to 14800, little to date has been done to develop a standardized legend. The main problems associated with producing a standard legend are to provide a unique symbol for each feature, to be able to computer-program the symbols, to implement the standard once it is adopted, and the upkeep of the standard. These problems and their solutions are addressed in the presentation. 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.
