Automated 3D Geological Surface Modelling With CDT
نویسنده
چکیده
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 were subsequently trimmed. To maintain an acceptable level of performance in setups consisting of typical graphics hardware, a Level of Details (LOD) algorithm using regular grids managed in a binary tree data structure was deployed.

متن کاملFundamentals of 3D modelling and resource estimation in coal mining
The prerequisite of maintaining an efficient and safe mining operation is the proper design of a mine by considering all aspects. The first step in a coal mine design is a realistic geometrical modelling of the coal seam(s). The structural features such as faults and folding must be reliably implemented in 3D seam models. Upon having a consistent seam model, the attributes such as calorific val...

متن کاملGeological 3D modelling: Scientific discovery and enhanced understanding of the sub-surface, with examples from the UK
In recent years, with the improvement of computer processing power and the development of sophisticated visualisation software, the traditional static views of geological maps, cross-sections, and other analogue representations have been replaced by digital, three dimensional (3D) models. Building these 3D models involves the assembly of many previously isolated and disparate datasets into a si...
متن کاملAutomated geological interpretation of cone penetration test data to model the subsurface of the Netherlands in 3D
Currently, visually described borehole samples are the primary input for large-scale 3D geological models of the subsurface, both when modelling architecture and composition. Cone penetration tests are rarely used and to a limited extent only. There are several reasons why it is of interest to utilize CPT data for geological and lithological modelling of the Dutch subsurface: 1) CPTs are more a...
