Application of Two Rendering Techniques in the Visualization of 3D Geospatial Data

AbstractGeo-scientific engineering is an ongoing project to obtain data, analyze data and process data, especially in the geological engineering investigation, design and construction process. We aimed to quick process and timely feedback of all kinds of unexpected data and information to guide the construction. Visualization technology is used to effectively and intuitively process and synthesize data. The dataflow model of 3D visualization process is described, and the visualization technologies are introduced to construct the geo-objects from 3D geospatial data. The applications of 3D visualization technologies to the analysis and processing of geological engineering data will improve the management and utilization of various geological engineering data for the engineering staff, and will promote the geo-scientific work effectively towards the direction of digitalization and visualization
