Several key techniques in 3D geological modeling including planar mesh generation, spatial interpolation, and surface intersection are summarized in this paper. Note that these techniques are generic and widely used in various applications but play a key role in 3D geological modeling. There are two essential procedures in 3D geological modeling: the first is the simulation of geological interf...

The display of three dimensional geological body can visually describe the complex subsurface geological structure, effectively improve the engineer's space imagination and intuitively understand the geological spatial relationship. Through analysis of commonly used three dimensional geological data model and considered the impact of faults. The paper establishes a generalized triangular prism ...

According to EuroGeoSurveys, the European Geological Surveys association, “Geological spatial data and models describe the solid Earth’s surface and subsurface on-shore and off-shore, its nature, structure, properties, dynamics and evolution over time; including its related (geo)resources and (geo) hazards”. This illustrates a modern vision of the core mission that National Geological Surveys h...

We document and discuss a number of interface explorations conducted while building a cable-array robotic sculpture in the form of a fiberglass bio-mimetic flying manta ray. Our two primary interface devices were a gesture sensing Essential Reality P5 glove and a Microsoft Xbox 360 game controller. We also offer a conceptual design space comprising three axes: mapping, frame of reference, and i...

Computed tomography (CT) of the lumbar spine was performed with selectively positioned 5-mm-thick axial cross sections to examine each disk level from the top of the neural foramen to the pedicle of the next caudad vertebra. One hundred consecutive patients with 116 surgical disk explorations were reviewed. There was agreement between the CT and surgical findings in 89 patients (104 exploration...

One of the advantages of the TNM classification of malignant tumours is that it does not require a minimum number of explorations. This allows the different specialists who are involved in the management of lung cancer patients to assess the anatomical extension of the disease regardless of the medical setting in which they work. A drawback of this universal applicability of the TNM classificat...

During any meta-heuristic search, two opposite processes are found in action, namely the explorations and exploitations. Although they might seem to operate in opposite directions, they are actually counterparts, and synergy between them may improve the final outcome of the algorithm. This is especially true for complex, high dimensional problems, because the search algorithm has to avoid many ...

Current techniques for providing collaborative visual analysis of remote scientific data using the Internet are reviewed. It is shown why the tools in common use today, such as Microsoft’s NetMeeting, do not provide scientists with highly interactive viewing of high resolution dynamic scenes of remote data when using typical Internet connections. New tools that do provide these capabilities in ...

The current metadata modeling techniques can not meet the needs of knowledge conception expression, knowledge organization, and metadata semantic consistency in geological domain. This paper introduces ontology and integrates this theory to geological domain metadata modeling. It adopts the first order logic equivalent algorithm and defines the metadata extended model as a quaternion group whic...

Electrical Resistivity Imaging (ERI) is an in-situ geophysical method widely used in environmental, engineering and hydrogeological explorations due to cost, time, data coverage efficiency. Traditionally, geotechnical parameters such as discontinuities properties are obtained from rock samples acquired a borehole. However, it only provides single information point, costly time-consuming. Thus, ...
