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。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 speckledata as well as the spatial distributing and connection, with modeling the selection process- ing. The subjective influence as well as instability has being released or decreased, with improving the quality and effect of the generalization.
