在电子地图设计的研究中,“用户界面设计”、“三维景观表达”、“多媒体的使用”、“动态注记”、“图形冲突”和“屏幕地图的交互功能”等都是至关重要的问题。然而在电子地图日益普及的今天,对这些问题的认识还需进一步的研究。本文结合《北京市电子地图集》的创作实践,详细讨论了电子图集的功能设计和界面设计,对以上问题提出了切实可行的的解决方案,并给出了较为理想的试验结果

Electronic map is the main method of visualizing geographical information. Following the popularization of all kinks of digital maps and web maps products, the design of the electronic map has become more and more important and constituted one of the key study fields in geo science and modern cartography. In study on design of electronic map, “design of user interface”, “presentation of three dimension land sight”, “application of multiple media”, “conflict of figure”, “dynamic annotation”, “interactive function of screen map” are important and unavoidable problems. Even though the electronic map is becoming more and more popular, these problems still need to be further studied. The paper summarizes and analyses the issues concerning electronic map design, discusses the theory of electronic map design, puts forward suitable method of data organization and technique of “multiple presentation”, and thus realizes “dynamic annotation” and efficient “space index” method. It provides basic services for better viewing: zooming and panning, rotation, virtual movement of the observer over 3D graphics, enlarging selected elements of graphics, etc. This system realizes the integration of graphic data and attribute data, so graphical presentation reflects the results of querying a database and is immediately updated when the user changes the query conditions. There are several linked displays of the same data set. The user selects some objects or data subsets in one of the displays, and the corresponding objects or data are highlighted in all the displays. The dynamic manipulation techniques available in this atlas are illustrated not only with pictures but also with “live” maps. In the end, based on the practice of the “Electronic Atlas of Beijing”, the paper discusses the design of interface and map function of the electronic atlas and several important issues on design of electronic maps are discussed in detail..
