基于Java Servlet方式的等值线生成系统的设计与实现

RESEARCH AND IMPLEMENTATION OF ISOLINES GENERATING SYSTEM BASED ON JAVA SERVLET

本文研究了WebGIS下基于Servlet方式等值线的绘制方法。在讨论了等值线生成的基本算法 ,包括离散点的网络化、等值点的确定与搜索、未知点的插值以及使用矩形网格进行边界裁剪等方法的基础上 ,设计和实现了基于Servlet方式的等值线生成系统。

In this paper,drawing isolines based on Java Servlet in WebGIS is mainly studied.At first,the algorithms of generating isolines using triangular meshes are introduced,including gridding discrete points,identifying the equivalence points and interpolating the points whose values are unknown as well as border clipping using rectangular meshes;then drawing isolines system based on Java Servlet is designed and implemented.
