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

Abstract

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 wellorganized 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.

The Application of Visualization Technique to Tidal Current Forecasting in China Offshore Area

“…Through the visual platform of the system, the forecasting results can be displayed conveniently, the movement procedure of the flow field can be shown lively and intuitively, which has more advantages than other traditional means of data analysis. Some scholars have already did some research on the application of visualization [2][3][4][5]. In order to study the tidal current of china offshore area, a tidal current forecasting mathematic model was built, and the methods to visualize the calculation results based on the MSChart control and Matlab toolbox were discussed.…”
