依据地图感受论和地图符号学原理,结合世界电子地图的显示要求和使用特点,针对世界电子地图中数据分级体系不完善、尺度建立不规范等问题,提出了一套世界电子地图多尺度表达分级体系,重点研究了基于SuperMap数据处理的技术方法、分类分级标准和符号设计理论,设计制作了基于SuperMap多尺度世界电子地图。 更多还原

【Abstract】 Based on the principle of Cartographic Experiences Theory and Cartographic Semiotics and combined with the display requirement and feature of world electronic map,this paper proposed a data staging system of multi-scale display of world electronic map,which focused on the research of technique of data processing,data staging standard and the theory of symbol design based on SuperMap,and made a multi-scale display of world electronic map based on SuperMap. 更多还原
