以提高定位精度为导向的电子地图应用策略研究
|
摘要
文中针对电子地图定位精度不够,现实的工作和生活中地理状况变化频繁,电子地图更新滞后的现状,提出一种以提高定位精确度的动态共享电子地图应用策略。通过构建实时共享的大容量网络信息平台作为数据支撑,在电子地图的信息点中链接动态图文信息,提高电子地图精确度,最大限度提高电子地图信息的即时性,兼具可视化的特点。该策略可作为电子地图的扩展,在特定行业或区域(如餐饮、旅游)中实施。
Since the electronic map is not accurate enough in positioning,the geographical condition often changes in real work and life,and the electronic map is not updated in time,this paper proposes a dynamic sharing electronic map application strategy to improve the positioning accuracy.Based on constructing the real-time sharing large capacity network information platform as the data support,the information point in the electronic map is linked with the dynamic graphic so as to improve the accuracy of the electronic map,as well as the betimes of the information with the feature of visualization.As the expansion of electronic map,this strategy can be used in a particular industry or area(such as catering,tourism).
