图斑数据自动概括中面向地理特征的层结构选取

Selection of Speckle-data Based on Layer-structure Construction in Cartographic Generalization

    摘要
  • 摘要: 在信息定义和结构化选取的基础上,根据图斑的空间分布与距离联系,给出图斑数据地理要素层结构的定义和建立过程,从而实现图斑数据制图概括中对象选取的模型化。

     

    Abstract: In this paper,the definition and construction algorithm of layer-structure of speckle data are proposed based on the measure of information and structured selection of speckle-data as well as the spatial distributing and connection,with modeling the selection processing.The subjective influence as well as instability has being released or decreased,with improving the quality and effect of the generalization.
