Neighborhood-Based Adaptive Geovisualization on Mobile Map

摘要: 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尺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。Abstract: Three main visualization issues of present mobile maps arediscussed,i.e.geoinformation unbalance between sheets,symbol 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.
