Mapeamento geológico com aplicação do BGS digital workflow e modelagem implícita

Abstract

Geological Mapping, one of the mineral geological activities, is associated with risks and investments, the methodology applied must guarantee the reliability of interpretation and presentation of the data. GIS Geographic Information Systems have proven to be one of themost decisive of the technologies involved in the process, which ensures the integration of data and information and greater objectivity in identifying value. Considering that the geology needs to be understood in the entire three-dimensional complexity of their shapes, geovisualization would be more effective if it were conducted in three dimensions (3D) with the association of realistic images, providing a representation in virtual reality VR. The association between GIS and VR will lead to a new benchmark in geological mapping research activities, in the acquisition of field data and in the analysis, discussion and visualization of results, which hasbeen applied by the British Geological Survey (BGS). As such, the objective of this article is to identify the parts of the process, which can be improved using a geotechnological approach, and implicit modelling, because since the XIV century, the results of the geological mapping arepresented in 2D (Maps and Sections). The work includes a pragmatic assessment of geological mapping activities and the identification of the activities that could be improved, starting from a methodological discussion and application of the methodology in a case study.
