Construction of a 3D model of geology in Sardinia using GIS methods
In spite of being a rather young branch of science, 3D modelling of geological structures using GIS techniques has grown rapidly during the recent years. There is, however, various approaches towards constructing an optimal 3D model of geology, depending on the cost, scope of the project and completeness of data to constrain the 3D model of geology. Undoubtedly,the more information and investments are , the better the final result would be. In this study, we introduced a method to first construct a cost-effective 3D model of a platform, in Sardinia, Italy and afterward, we tried to verify the proposed model and constrain the result with the geological interpretations. The result indicates that different geo-morphological layers can be identified using isovalues in the final 3D model.The fast prevalence of GIS application in geological studies is an undeniable issue; this mutual cooperation is therefore profitable for optimum understanding of geological studies.
