摘要：In order to provide users with more diverse varieties of new GIS products that contain richer content, it is proposed that Image topographic maps and hill-shading topographic maps should be produced as the DLG topographic maps offered in the 1:50 000 topographic mapping of blank areas in the western region, China. This paper first describes the contents contained in the Image topographic map and hill-shading topographic map, and principles about how to represent them. Then, the technological process of produce Image topographic map and hill-shading topographic map are given. Now, two technical specification documents that specify how to produce Image topographic maps and how to produce Hill-shading topographic maps have been put forward based on some experiments, and the study results have been applied to the 1:50 000 topographic mapping of blank areas in the western region project. It demonstrates that the Image topographic maps are good supplementary products for topographic maps, which can provide more texture information for users, and the Hill-shading topographic maps are good substitute products for topographic maps in some areas, which can represent characteristics of terrain and surface features better
