Database Application in Visualization of Process Data

An information system for visualization of Underground Coal Gasification (UCG) has been developed. The main goal for the system is to provide means for better understanding and control of the process. The system uses mainly data generated during UCG process numerical simulation. Apart from that, the system is capable of storing and visualizing measurement georadar data, gathered during in-situ processes. Development software consists of three modules: the data acquisition, data preprocessing, and data visualization. All modules communicate through a database, the central point in the system architecture. Data from modeling or measurements are stored in database in raw format. Then the preprocessing module converts them for visualization purposes. The visualization module shows preprocessed data to the user using 3D graphics. The visualization is dynamic (visualized data changes in time) and allows observing several properties of the process - gases concentration, gasification cavern development, and so on. The software was developed using. NET framework and XNA Game Studio 4.0 library.
