提出了基于邻近的移动地图自适应可视化方法,其基本原理是将邻近关系作为地图比例足调节和地图更新的依据,并通过实验系统证明了该方法的可行性与有效性。
Three main visualization issues of present mobile maps arediseussed, i.e. geoinfor marion unbalance between sheets, syrnbol fragments and unreasonable updating frequency. Then an adaptive geovisualization method is proposed, which selects geo objects, calculates adaptive scale, and updates map based on neighborhoods. Experiment result proves this method is feasible and valid to overcome three problems mentioned above.
