对地理数据所隐含空间特征的探测是GIS理论研究和工程应用的关键问题之一。提出了一种基于Delaunay三角网的空间特征探测模型,该模型可用于点、线、面等多种几何类型的多种空间特征的探测,如点群目标的空间分布范围、分布密度和分布轴线探测,线目标的弯曲特征探测,多边形目标的瓶颈区域探测,多边形群的分组聚类特征探测等。实验证明,基于该模型的探测结果满足空间认知的基本原则。 更多还原

【Abstract】 The detection of spatial characteristics of GIS data is one of the key points in GIS theory research and engineering applications.This paper present a delaunay triangulated irregular network based model,which adopt to all three geometry types(point,polyline and polygon) and could detect many types of spatial characteristics,such as distribution extent,density and skeleton for point cluster;bend structure for line object;bottleneck area and subgroup for polygon and poly-polygon.All these methods ... 更多还原
