Abstract

Topographical data is an essential of structural designing foundation projects. Notwithstanding, the displaying,portrayal, update, and trade of geographical data are testing since they are overseen by heterogeneous information models upheld by the two-layered (2D) portrayal that needs volumetric data, 3D perception, and coordination. This study presents an original land information model utilizing BIM and GIS to work with three-layered (3D) displaying and the board of geographical data. The IFC and CityGML ADE are extended to accommodate the significant geometric, semantic, and spatial information contained in the proposed geological data model. IFC and CityGML were used to map the BIM and GIS data. Besides, the proposed geographical information model purposes a limit and voxel mathematical portrayal for the topographical information. Calculations are created to make an effective 3D geographical limit and voxel model in light of the created land information model. Moreover, the voxel size,number, and traits can be refreshed effectively, empowering the portrayal of geographical data at various scales.In this manner, the proposed BIM-GIS system is exhibited for a situation concentrate on utilizing geotechnical examination information from a city. In order to confirm the proposed method's practical applications, a survey using a questionnaire was carried out. As a result, it was discovered that the proposed method improves the efficiency of geological data management as well as the process of exchanging geological information.

This paper primarily provided a synopsis of a special issue titled "Application of Novel High-Tech Methods to Geological Hazard Research."This issue covers a variety of aspects of geological hazard prevention and mitigation, including characteristics and mechanisms, numerical simulations, susceptibility and hazard assessment, monitoring and early warning, prevention and control measures, and geotechnical research of geological hazards. The application of cutting-edge and novel approaches to the prevention and mitigation of geological disasters was further pushed forward by these studies.
