3D Geological Modelling and Management System

Computer Modelling of 3D Geological Surface

— The geological surveying presently uses methods and tools for the computer modeling of 3D-structures of the geographical subsurface and geotechnical characterization as well as the application of geoinformation systems for management and analysis of spatial data, and their cartographic presentation. The objectives of this paper are to present a 3D geological surface model of Latur district in...

Automated 3D Geological Surface Modelling With CDT

Advances in computer technologies make it possible to create three-dimensional and interactive geological information systems. A Constrained Delaunay Triangulation (CDT) algorithm which considered the line segments of the geological polygons as constrained edges and all vertices of the digital elevation model (DEM) inside the polygons was applied to construct CDTs. Triangles outside the polygon...

Rigorous 3d Geological Models as the Basis for Groundwater Modelling

Increasing environmental pressures, pollution and legislation in Europe are creating the urgent need for regional-catchment scale geological models to assess hydrogeological conditions and inform mathematical and numerical groundwater models. Geological models are especially important in areas with superficial deposits overlying key aquifers. These areas are often characterized by very complex ...

3D Modelling of Geological Fossils and Ores by Combining High-resolution Textures with 3D Scanning Data

Remote 3D virtual reality systems for visualizing fossils and ores are a kind of efficient tools to facilitate communication and research in geology and palaeontology community. During the visualization procedure, we must keep not only the geometrical data but also the surface textures and color information. They are very important for the specialists to analyse the forming time and environment...
