Study on Marine On-Line Analysis WebGIS System

Geographic Information System (GIS)has a wide range of applications in many areas. The project "the Bohai Sea ecological environment real-time monitoring demonstration system" uses the ships which carries the fast observation system, the ecology buoyage, the submarine automatic inspection station, and other monitoring measures to carries on the monitoring to the Bohai Sea ecological environmental conditions. This paper discusses the application of marine environmental protection on-line analysis webgis system, the paper explains how to take WebGIS and other information technology as the technical support, established the internet website of marine information system based on the ArcIMS platform. It can intellectualized gain monitors of the environment information, and can draw the information products such as the plane distribution map, time series form and curve, form, data file, stick plot or cake chart of the marine monitoring data on net, to satisfies each kind of users.
