基于SVG技术的室内地图设计与实现

Design and Implementation of Indoor Map Based on SVG Technology

室内环境导航的需求在今天越来越受关注。目前现有的室内环境地图采用常见的瓦片技术,但它限制室内环境的展示。室内地图与室外地图的特征有着许多区别,尤其是存储室内地图的数量级远小于室外地图。此外移动终端的性能不断提升,能够处理更多更复杂的任务。基于此,室内地图在移动终端独立完成地图解析和展示的任务变得可能,且不影响用户体验。实验证明,采用SVG作为室内地图的数据源,在移动终端解析和展示是可行的,并有更好的用户体验。

The needs of indoor environment navigation in today＇s increasingly cause for concern. Currently existing indoors environment map use a common technology that calls it tile map technology, but it limits the display of the indoor environment. Indoor and outdoor map feature has many differences, in particular the storage space is far less than the outdoor map. Besides ,with the performance of mobile terminal rising, it can handle more complex tasks. Based on this, indoor maps in the mobile terminal independently map the task of parsing and display becomes possible, without affecting the user experience. Experiments show that uses SVG as indoor map data source parsing and display of the mobile terminal is feasible and has a better user experience.
