A New 3D Geological Modeling Method and Its Application in Chengdu-Changdu Region Modeling

More Information
  • Under the background of the deepening of geological research and the vigorous development of geospatial information science 3D visualization geological modeling technology has become a research hotspot in the interdisciplinary fields of information science and earth science. In this study, the traditional 3D geological modeling method is studied and improved to form a new 3D geological modeling method. The new 3D geological modeling method is mainly applied in the geological field, and new progress has been made in multi-source heterogeneous geological data fusion, large-scale high-precision modeling, geological grid subdivision, attribute modeling technology, remote sensing image fusion and other aspects. Taking the Chengdu-Changdu region as an example, this paper uses the new generation of 3D geological modeling technology to carry out 3D geological modeling and visualization with geological borehole data, Chengdu map, Changdu map and remote sensing data as data sources. The 3D visualization of Chengdu-Changdu region verifies the feasibility and effectiveness of the new 3D geological modeling method. At the same time, it also provides an important method for the national important geological borehole data service platform to publicly release 1.1 million important borehole data 3D geological modeling covering 31 provinces (autonomous regions and municipalities) in China with a cumulative depth of 275 million meters.
