随着网络地图的兴起以及地理信息在各行业中的应用，兴趣点已经成为地理信息应用中不可或缺的一类要素，在地理信息应用中起到越来越重要的作用。但随之而来的，跨比例尺间的兴趣点取舍问题却成为了地理信息应用中的一个难点。提出一种基于Delaunay三角网的跨比例尺点要素综合算法，结合空间和属性特征解决了跨比例尺兴趣点的取舍问题。

With the rise of the network map , and geographic information applications in various industries , interest points has become an integral part of the geographic information features and play an increasingly important role in the geographic information application .But the ensuing cross-scale interest point trade-off has become a difficult geographic information applications .This paper presents a delaunay triangulation-based cross-scale point feature algorithm combi-ning spatial and attribute characteristics to solve the problem of cross-scale interest point of the trade-offs.
