摘要
多媒体文件在丰富地图集内容、增强交互性与表现力的同时往往影响了地图集对用户操作的响应速度,并且已经成为多媒体电子地图集开发中的瓶颈问题之一。本文首先分析了影响多媒体电子地图集操作速度的各种因素,然后以《福建省生态环境多媒体电子地图集》的数据组织方法、系统结构、操作功能、地图界面和多媒体要素设计为例,说明如何设计并实现对用户操作快速响应的多媒体电子地图集。
The responding speed is a bottleneck in multimedia electronic atlas development. This paper analyses the problem at first. It tries to find the role every part in the atlas acts and how they affect the responding speed on earth. Following this, it gives some means respectively to solve the problem in the structure, the associated mechanism, the functions, the interface and the multimedia elements. Then a whole visual example of 'Electronic Atlas of Ecological Environment in Fijian' consisting of seven map groups and an inbuilt web is put up to illustrate how a multimedia electronic atlas should be designed taking into account of responding speed enhancement for many interface instances.
