| Abstract: | 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. |
