等值面快速生成方法的改进

Improvement of Isosurface Fast Generation Method

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Model Builder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。

Aiming at disadvantages of low efficiency and weal interaction in isosurface generating method easy migration from C/S mode to B/S mode, this paper presents an isosurface fast generation method based on ArcGIS Server. It relies on the ModelBuilder of ArcGIS Server to generate models and services of geoprocessing service, generates surface using Web Service of Server resources through Simple Object Access Protocol（SOAP） and renders in client side. Application of three prevention decision-making and supporting subsystem in Dongguan city, results show that this method well meets the need of efficiency, interaction and visual beauty aspect, it also can reduce the capacity of network transmission and improve the performance of GIS analysis.
