A Study on Remote Visualization of "Ocean Vector Field Data"Based on Web Service
基于Web服务的海洋矢量场远程可视化研究

Nowadays,the visualization of GIS spatial data is in static manner,and the data is managed on the server side concentrically.So,it is difficult to satisfy the need for the multi-source and different structure data.At the same time,it also can't meet the need for the ocean environment information data,which has a strong attribute of dynamics.With the development of web service and grid computing technology and also with the utilization of these technologies in GIS,it is possible to realize the visualization sharing of spatial data in a uniform client and manage these data in a distributed way.So,firstly,the article analyzes the requirement of visualization sharing of ocean vector fields information on network in real time and its technologic difficulties.Then the article introduces the web service and network GIS technologies,which are the theoretical base of the systeam,and discusses the method and the system structure of ocean environment vector fields network visualization system in detail.Finally,the article took ocean current data as a case study,introduces the realization of network real time visualization platform of ocean current data with the support of network service of ArcGIS and visualization of ArcEngine.The experimentation has proved that the ocean current remote visualization system based on web service can meet the requirement of data access and visualization for vector fields in network.
