一种基于C-Tree的属性数据综合方法

A method of attribute data generation based on C-Tree

无级比例尺GIS是GIS发展的目标,空间数据的自动综合是实现无级比例尺GIS的关键。针对GIS中属性数据的综合问题,分析了几何数据综合与属性数据综合之间的关系,提出了一种由几何数据综合触发属性数据综合的模式。在此模式上针对专题属性数据提出了一种基于C-Tree的数据综合方法。

Scale-less GIS is the target of GIS. The auto generation ot spatial clata is one ot me Key tecnnologles of scale less GIS. To the problem of attribute data generation, a mode that geometrical data generation induced attribute data generation is proposed by analyzing the relation of them. Then an attribute data generation algorithm based on C-Tree is presented under this mode.
