基础电子地图显示的关键技术

电子地图在走向产业化、实用化的过程中,人们越来越感到电子地图的显示所产生的问题不能被忽视。目前,对电子地图显示缺少系统的研究,特别是从理论、技术和实际应用层面相结合的研究还比较少见。因此,在分析基础电子地图显示存在问题的基础上,以地图制图理论为指导,研究了基础电子地图的显示特点,提出了基础电子地图显示研究的理论框架,并针对基础电子地图自适应变焦显示、可视化表达以及显示风格转换系统的研制等关键问题进行了探讨和实践。

Key Technique of Basic Electronic Map Display

Presently the problem in electronic map display has effected the use and industrialization develop more and more.Although many scholars have realized the importance of electronic map display,there is lack of systemic study,especially the paper on combining the theory,technology and practicality application.Therefore,this paper studied the characteristics of basic electronic map display and proposes its study theory framework,which based on analyzing the problems in basic electronic map display and under the theory of cartography.At last,it discussed and practiced the key problems of adaptive zoom display in basic electronic map,visualization and studying of display style switch system.
