针对网络地图可视化表达问题,分析了网络环境下多变量制图数据的特点,研究了网络多变量制图数据的组织和可视化策略,提出了一种采用Mashup思想进行网络地图多变量制图的方法,根据该方法实现了一个网络多变量地图制图原型系统,并将其应用于资源三号卫星影像制图等相关项目。
For the purpose of solving the arrangement and representation problems in multivariate web mapping, firstly, the research status of the visualization and mapping methods for multivariate web data are analyzed, after that, the demand and characteristics of multi-variate mapping data for the web environment are investigated, and then the arrangement of the multi-variate web mapping data and the visualization strategy is discussed in detail. Based on the previous research, a multi-variate web mapping method using Mashups is introduced from aspects of theory, strategy and technology. A prototype system designed for multi-variate web mapping was developed, and the prototype system was applied to related Resource-3 satellite image mapping programs, the successful implementation of the method shows that it can improve mapping efficiency and the representation effect in multi-variate web mapping.
