海陆一体化电子地图显示的符号设计

Symbol Design of Sea-land Integrated Electronic Map Display

针对海陆一体化电子地图显示中符号设计存在的问题,运用电子地图空间认知论、电子地图视觉感受论等理论探讨了海陆一体化电子地图显示符号设计的原则,总结了海陆一体化电子地图中陆地电子地图海部要素符号、电子海图陆地要素符号和海陆交接处要素符号设计的方法,根据显示要素的特点,对海陆一体化符号进行了设计与试验,为海陆一体化电子地图显示奠定了基础。

In view of the symbol design problems of sea-land integrated electronic map display,we exert the electronic map spatial cognition ism,visual perception ism and etc to discuss the principle of symbol design of sea-land integrated electronic map display.Then,we summarize the symbol design methods of marine elements in land electronic map,land elements in electronic chart and elements on sea-land junction.Finally,based on these symbols we take some experiments which lay a foundation for the sea-land integrated electronic map display.
