Modeling and mapping in geological surveys

A geological survey is a systematic investigation into a given area for the purpose of creating a geological map or model for construction. Using techniques from the traditional survey, surveying trails and terrain, with intrusion methods, such as hand drill holes and drills, to use geophysical techniques and methods. Remote sensing, such as aerial photography and satellite imagery.

Geological survey report

Such surveys may be conducted by provincial or national geological survey organizations to maintain geological, inventory and geoscience knowledge for the benefit of the state. . Geological mapping usually describes the scope of the survey and the boundaries of geological units on topographic maps, along with information at points (such as orientation of the bed surface) and straight lines (such as intersection of faults with ground).

Maps and reports generated by geological survey organizations often aim for continuity and completeness of geography in the establishment of spatial models of near-surface rock units. The map may include cross sections to illustrate the three-dimensional representation. Geological and geophysical maps below the ground provide limited geological coverage (known, for example, from oil or gas drilling), maintained internally by oil companies. large mines and managers.

Several geological survey units have collaborated with them to include geological subsoil in their systematic surveys, for example, geological maps of sedimentary basins. A sub-surface map usually describes the three-dimensional shape of the geological surface by means of lines and cross sections. Computer-based models are increasingly being used to provide more comprehensive and flexible information storage capabilities in presentations.

Conclude

In a nutshell, it is understandable that, since exploratory surveys have been conducted, the reports are presented as drawings or models. Layers of sedimentary rocks with different characteristics will be clearly demonstrated to the geological survey drilling works, renovation of foundations.
