面向模型的大比例尺制图综合框架设计与实现

Framework Design and Implementation of Model-Oriented Cartographic Generalization

模型综合作为制图综合的一部分 ,是通过改变地图内部目标关系的表达方式 ,使地图的表达更简单 ,进而使综合更方便。结合交互式制图综合软件AutoMap ,介绍了面向模型综合的系统设计框架和具体实现 ,并着重从地图目标的空间关系、几何属性和语义关系 3个方面来分析模型综合。

Model generalization is a component part of map generalization, which modifies the internal representation of map objects, makes it simpler and makes the task of generalization more convenient. According to the map generalization software 'AutoMap',a circular framework supporting this task and its implementation, and analysis of model generalization based on a separation of the topological, metric and semantic aspects of map objects is presented in the paper.
