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software, the traditional static views of geological maps, cross-sections, and other analogue representations have been replaced by digital, three dimensional (3D) models.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...

Although many of the first-generation Digital Earth systems have proven to be quite useful for the modeling and visualization of geospatial objects relevant to the Earth’s surface and near-surface, they were not designed for the purpose of modeling and application in geological or atmospheric space. There is a pressing need for a new Digital Earth system that can process geospatial information ...

this paper describes the application of approximate methods to invert airborne magnetic data as well as helicopter-borne frequency domain electromagnetic data in order to retrieve a joint model of magnetic susceptibility and electrical resistivity. the study area located in semnan province of iran consists of an arc-shaped porphyry andesite covered by sedimentary units which may have potential ...

This paper presents a geological application in a virtual immersive environment : the Immersive Geological Pilot. This application allows a user to interactively build a structured geological model and its associated geological evolution scheme (a directed acyclic graph) by setting the various geological surfaces of the model one after the other in reverse chronological order, beginning with th...

in recent days, computer is becoming one of the most essential instruments in advanced countries for the researchers and the domain of its application is going to be increased every day. using the 3d modeling of the earth, its mine resources and the brilliant details which are given by the models, the researching and exploring groups will find out the inconspicuous and attractive aspects of the...

In this paper, we discuss some novel techniques for modeling sedimentation and compaction using fully unstructured meshes. The numerical modeling of the sedimentation process is a critical part of basin simulation and synthetic stratigraphy modeling. Normally, structured curvilinear meshes are used to represent sedimentary sequences to be deposited during the simulation. Using this approach, 2D...

This paper addresses one of the key components of the mining process: the geological prediction of natural resources from spatially distributed measurements. We present a novel approach combining undirected graphical models with ensemble classifiers to provide 3D geological models from multiple sensors installed in an autonomous drill rig. Drill sensor measurements used for drilling automation,...

Three-dimensional mapping has extensively developed in the last decade; geological mapping being the area where these developments are more striking. 3D geological mapping has a myriad of applications in the domains of basin analysis, geophysics, geostatistics, geothermal and energy resources, etc. A parallel domain of development has been three-dimensional groundwater modelling: regional groun...

Most 3D geological modelling tools were designed for the needs of the oil industry and are not suited to the variety of situations encountered in other application domains. Moreover, the usual modelling tools are not able to quantify the uncertainty of the geometric models generated. The potential-field method was designed to build 3D geological models from data available in geology and mineral...

this study deals with the 3d recovering of magnetic susceptibility model by incorporating the sparsity-based constraints in the inversion algorithm. for this purpose, the area under prospect was divided into a large number of rectangular prisms in a mesh with unknown susceptibilities. tikhonov cost functions with two sparsity functions were used to recover the smooth parts as well as the sharp ...
