图斑数据自动综合中面向地理特征的层结构选取

The Selection of patch-data based on layer-structure construction in cartography generalization

本文在信息定义和结构化选取的思想基础上,给出图斑数据地理要素的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。

In this paper, a new definition and construction algorithm of layerstructure is proposed based on the measure of information and structured selection of patchdata, with modeling the selection process. The subjective influence as well as instability is being released or decreased, with improvement of the quality and effect of the generalization.
