THE INFLUENCE OF SCIENTIFIC VISUALIZATION TO THE ENGINEERING GEOLOGICAL DATA PROCESSING

According to the specific requirements of geological disaster prevention to geological exploration in the three gorges reservoir area, based on the database management system(DBMS), computer aided drawing system(CADS), geographic information system(GIS)technology and 3D modeling and spatial analysis technology(3DAS), discussed three key technical problems caused by scientific visualization: through the combination of geological interpolation and mathematical interpolation to improve the precision of the 3 d model, through the combination of 3 d model and database to enlarge the traditional CADS and through the double C(Center, data Center and application Center) model to process the system integration, Provide visual expression and analysis support from the area to the point, from the ground to the underground for disaster geological research and prevention.
