中国1∶100万数字地貌图符号与注记系统库的设计和应用

中国1:100万地貌图符号系统库和注记系统库的设计,是在对中国区域地貌的形态与成因类型特征全面综合分析研究的基础上,针对中国1:100万地貌图的基本专题内容、图例系统、幅面负荷等的要求,从定量制图符号的基本问题出发,根据不同地貌形态和成因类型,设计各种点状、线状、面状符号和注记,建立了地貌符号库。同时,构建了满足1:100万地貌图制图和出版要求的地貌注记库。它们均应用于《中华人民共和国地貌图集(1:100万)》中,达到了预期设计效果,该地貌符号和注记库的设计和内容对其他相关专题图集的编制具有很好的借鉴意义。

Design and Establishment of Symbol and Annotation System Database for 1∶1000000 Digital Geomorphologic Map of China

Based on analysis and research on characteristics of regional geomorphology of morphological and genesis types in China,the basic content and legend system of 1∶ 1 000 000 geomorphologic map of China were fully understood.Starting from the basic issue of analyzing quantitative cartographic symbols,this paper designs various point,linear and polygonal symbols and annotations according to different morphological and genesis types,so as to establish quantitative cartographic symbol and annotation database.The parameter types of symbol system includes its shape,size and color,and the symbol system database of the geomorphologic maps of 1∶ 1 000 000 of China includes point,linear and polygonal types,come to about 278 types.The annotation contents include character,numbers and letters etc.,the parameters of annotation system possess character font,character size,character interval,character position and character color et al.The symbol and annotation system database was used in the geomorphologic maps of the People＇s Republic of China with the scale of 1∶ 1 000 000.
