| 摘 要： | 针对等值面生成方法从C/S到B/S的移植存在效率低、交互性差的缺点，提出一种基于ArcGIS Server的等值面快速生成方法，通过ArcGIS Server中的ModelBuilder创建模型，建立地理处理服务，以SOAP方式访问调用服务器提供的Web服务生成等值面，在客户端加以渲染。在东莞市三防决策支持子系统中的应用结果表明，该方法在效率、外观、交互性方面都较符合用户需求，可减少网络传输量并提高GIS分析性能。

| Abstract: | Aiming to improve the clustering quality and efficiency on banking services datasets, this paper proposes the concepts of cluster diameter and the similarity measurement between clusters. It modifies multi-dimensional data to one dimension by dimension reduction based on distance order. It clusters the one dimension data with a self-Adaptive Sort Clustering(ASC) algorithm. This paper conducts extensive experiments to show that this algorithm can improve the cluster similarity and reduce the clustering time compared with Cobweb and K-means algorithms. The cluster similarity can be approximately improved by 200%. |
