In order to realize the integration and sharing for multi-source marine data, the paper took the visualization application of the multi-source marine environment data as an example to discuss the realization way of the data’s integration and sharing. By encapsulating the marine environment data and its application model to web services, we constructed a multi-source marine environment data applying platform system framework through internet. The system can shield the data isomerism and the application environment isomerism, and realize the integration and sharing for the multi-source marine environment data. At the same time the distributed structure of the system can raise its flexibility and expansibility. So the establishment of the system proves the feasibility of web service in multi-source ocean environment data’s integration and sharing.
