Study on Data Process and Visualization System of Tide and Tidal Current

Nowadays, there are increasing amount of data fields of tide and tidal current gained from ocean dynamical environment real-time stereo monitoring platform, model calculation and numerical simulation. Collaborative visualization of these data fields on the internet is becoming increasingly important for the utility of data. In this paper, we summarize the characters of tide and tidal current data fields and introduce a data process and visualization system. We organize the original data follow a certain criterion, preprocess the data to improve the visualization effective, use snap-shot spatio-temporal data model to organize the data fields and display the changing process of tide and tidal current. Through a well-organized metadata database, data fields are well managed. By using Web services we provide proper services to meet the needs of both the public and professionals on the Internet.
