Geologic or geological modeling is the use of computerized science to create representations of potions of the earth’s crust. This is based on geological and physical observations made on the earth’s surface.
The data collected is used to make a geological map. The map has directions, domains of interest and descriptions of physical quantities. Geomodelling is used to manage natural disasters and to identify hazards. In two dimensions, a unit is represented by a polygon and it can be bounded by faults. A geological unit is bounded by 3D triangulated surfaces.
3D geomodelling involves the following:
- Analyzing of geological context of the domain being studied
- Construction of structural material or a model that describes boundaries or horizons
- Defining 3D mesh
- Interpreting of available data and observing set points
Geomodelling and CAD share a lot in common when it comes to technology. The graphical user interface consists of one or several two-dimensional and 3D graphics. Visualization is achieved by exploiting graphics hardware. The interactions are performed via keyboard and mouse. 3D pointing devises are also used in some cases.
Geologic modeling software
Developers have built some software and packages for geological modeling. The software can edit, display, digitize and calculate parameters automatically. Such software gotten from software vendors such as CTECH makes it easy to concentrate on other important issues. The software keeps on changing and companies must always be on the lookout for updates.
Two dimensional diagrams and guesses make it difficult to have the right data. 3D models help show a geographic location better and give accurate information.
Why do you need 3D geologic modeling?
- It is accurate.
- Very fast to use and apply
- Builds complex structures
- Can build structures using logs
3D graphical animations can be used to describe a site to a client. If a land or geographic location is heavily populated, it can be difficult to fully describe or draw a diagram without making any mistakes. 3D models will help you describe the location with ease.
Shore animation is created from available data and engineering maps. It helps illustrate the depth and extent of the water.
3D subsurface models illustrate the complex layering structures and show the location of sewers or the distribution of underground pipes. It can also show interconnection of layers.
Computerized models and animations are successfully made to show the impact of different geological hazards on the earth. 3D models can also be made for future reference. Each model is used to produce a dynamic animation that can tell what a project is about. The animation is easy to understand and you can always rectify in case there was wrong data. The animations given are clear and accurate but also depend on the data received. If you are a geologist, having a 3D model or animation will make it easier for you to collect more data and to analyze it.
