图斑数据结构化综合中的特征聚类选取

Selection of Speckle-Data Based on Layer-Structure Construction in Cartography Generalization

在信息定义和结构化选取的思想基础上,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,降低或消除了制图概括过程中人为操作的不稳定性和主观影响,改进和提高了制图概括的效果和地图的质量.

The definition and construction algorithm of layer-structure of speckle data is 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 is being released or decreased,with improving the quality and effect of the generalization.
