Geology is the base for highways and tunnels construction. With the fast development of national highway construction, highway tunnel construction project are more and more complex. The completeness and accuracy are essential for the planning, design and construction of projects, while the ground information is quite poor in systematic, reliable and timely aspects. Therefore, the development of...

With the development of GIS, its applications concern with different domains, such as geography, mapping, urban, traffic, geology, mine, military and so on. 3D GIS is the research hotspots in the domains of city, geology, mine etc. 3D GIS in city has been developed more quickly, CyberCity, for example is a smart application of 3D GIS, but it is slow in subsurface engineering because of its comp...

The wide-spread use of GOCAD [Mal92a, GC99] in the geosciences as an application for 3D-modeling makes it a significant tool for an open 3D-GIS environment. Therefore GOCAD should provide an open interface for an object-oriented data and methods exchange. Unfortunately, hitherto GOCAD’s 3Dobjects are not managed by modern database technology. Therefore it is proposed to develop a coupling betwe...

Three-dimensional (3D) modelling of geological body is an important issue of 3D GIS and 3D Geosciences Modelling, and one of the key technologies of digital mine. GTP model and its components are introduced in this paper. According to the relations between chronolith and rock attribute comprehensively, the modelling region, system, series, group and rock characteristics(RC) are regard as the sc...

Accurate modeling of seismic wave propagation in complex media is the key to many high end seismic processing algorithms. The performance is achieved by parallel implementation of algorithms on large compute clusters. This article describes the implementation of 3D acoustic and elastic wave propagation algorithms on a high performance computing system. A MPI (Massage Passing Interface) implemen...

With the development of high-precision geological observation technology, in situ mineral microanalysis isotope geochemical analysis deep geophysical exploration drilling, real-time mining, remote sensing high-resolution hyperspectral image and supercomputer industrial intelligence, geoscience has entered an era big data artificial intelligence 21st century [...]
