“…Unlike data acquisition in the traditional 2D GIS, 3D geological models cannot be obtained directly because of geological complexity, uncertainty, limitation of available useful data, etc., or direct acquisition is very difficult [15][16][17]. In practice they are mostly reconstructed from lower-dimensional data, such as boreholes [18], cross-sections [19,20], and multi-source data integration [21].…”

With the rapid urban growth in China, there is an increasing requirement for the multi-element 3D urban geological information system (MUGIS), which can provide diverse and timely urban geological information for scientific and rational urban planning, safe urban construction and effective urban management. This paper firstly analyzes the significance, history and current status of urban geological informationization. Add then, the architecture of MUGIS, including support system, guarantee system, technology system, the whole process informationization in urban geology survey (UGS) and service system, is introduced in detail. Furthermore, we discuss the software system and several key technologies. Urban geological data center provides the integration and management of the multi-source, heterogeneous, massive, multi-dimensional, multistage, multi-scale, multi-thematic urban geological data. Urban geological data engine is the middleware providing transparent access for urban geological data. Urban geological information management and service basic platform provides the basic software functions for data management, modeling, analysis and sharing based on the integration of 2D GIS and 3D GIS. 3D urban geological modeling, a very important and difficult step, is highlighted. Analysis and assessment Model Base is important in the assistant decision-making for new region and subway line planning, dumping site selection, selection of emergency water source bases, etc. At last, based on the research in this paper, the development and applications of MUGIS in Beijing, Hangzhou and Hefei, China are presented.

Following the example of other industrial activities, mining evaluation is now exposed to socio-economical and technological constraints which are unstable in quick evolution. The keys to its success are increasingly related to a methodology of work more scientific than ever. The Systemic Approach has broadly showed its effectiveness in numerous disciplinary fields, both scientific and engineering ones: Biology, Economy, Social and Management Sciences, Quality Management, Information Systems… Helped by technological progress, this approach has especially excelled in the management of spatial information (e.g. GIS). It constitutes therefore an excellent solution to the problems of mining evaluation by the integration of genetic, mining and managerial data within an Information System, thus optimizing scientific and economic valuation of mineral resources.

“…Since the proposal of 3D geoscience modelling in 1990s (Houlding S., 1994), there has been a series of proposed geological modelling methods, including section connection (Ming, J., 2010), GTP method (Wu L., 2004) and free form surface method (De Kemp E A, 2003) etc. Based on these methods, a number of geological modelling systems were developed (Qingyuan Li, 2013), such as GOCAD (Zanchi A, 2009), GeoModeller (Vance T C, 2007), GSI3D (Kessler, H., 2009) etc.…”

ABSTRACT:Three-dimensional (3D) geological models are important representations of the results of regional geological surveys. However, the process of constructing 3D geological models from two-dimensional (2D) geological elements remains difficult and time-consuming. This paper proposes a method of migrating from 2D elements to 3D models. First, the geological interfaces were constructed using the Hermite Radial Basis Function (HRBF) to interpolate the boundaries and attitude data. Then, the subsurface geological bodies were extracted from the spatial map area using the Boolean method between the HRBF surface and the fundamental body. Finally, the top surfaces of the geological bodies were constructed by coupling the geological boundaries to digital elevation models. Based on this workflow, a prototype system was developed, and typical geological structures (e.g., folds, faults, and strata) were simulated. Geological modes were constructed through this workflow based on realistic regional geological survey data. For extended applications in 3D modelling of other kinds of geo-objects, mining ore body models and urban geotechnical engineering stratum models were constructed by this method from drill-hole data. The model construction process was rapid, and the resulting models accorded with the constraints of the original data.
