“…They mainly want to describe and represent the geological formations of subsurface, and most of them are constructed based on extending exist functions of ArcGIS, MapInfo and MapGIS. James D and Phil A also constructed 3D geological application based on the functions of the ESRI`s ArcScene, and their system can show 3D geological scenes and query spatial information of borehole data [5]. Zhu Liang-feng and Pan Xin developed 3D geological application based on MapGIS which can represent the 3D geological bodies [6].…”

Construction of 3D geological visualization system has attracted much more concern in GIS, computer modeling, simulation and visualization fields. It not only can effectively help geological interpretation and analysis work, but also can it can help leveling up geosciences professional education. In this paper, an applet-based method was introduced for developing a web-based 3D geological information visualization system. The main aims of this paper are to explore a rapid and low-cost development method for constructing a web-based 3D geological system. First, the borehole data stored in Excel spreadsheets was extracted and then stored in SQLSERVER database of a web server. Second, the JDBC data access component was utilized for providing the capability of access the database. Third, the user interface was implemented with applet component embedded in JSP page and the 3D viewing and querying functions were implemented with PickCanvas of Java3D. Last, the borehole data acquired from geological survey were used for test the system, and the test results has shown that related methods of this paper have a certain application values.

“…Data for Geotouch needs to have some specific structures to finish the complicated work, which is a limit for the users to expand the data model. On basis of ArcScene (ESRI), McCarthy et al [13] developed BoreIS to manage, visualize, query, and analyze the borehole data. It can match the datasets in the tables and important geological conditions to discover the problems interactively.…”

Geological body structure is the product of the geological evolution in the time dimension, which is presented in 3D configuration in the natural world. However, many geologists still record and process their geological data using the 2D or 1D pattern, which results in the loss of a large quantity of spatial data. One of the reasons is that the current methods have limitations on how to express underground geological objects. To analyze and interpret geological models, we present a layer data model to organize different kinds of geological datasets. The data model implemented the unification expression and storage of geological data and geometric models. In addition, it is a method for visualizing large-scaled geological datasets through building multi-resolution geological models rapidly, which can meet the demand of the operation, analysis, and interpretation of 3D geological objects. It proves that our methodology is competent for 3D modeling and self-adaptive visualization of large geological objects and it is a good way to solve the problem of integration and share of geological spatial data.geological object, geological model, network transmission, visualization Geological objects are composed of different kinds of data, such as borehole data, topography data, rock and soil data, geophysical and hydrological data. Geological and borehole data, in particular, provide useful information about the earth surface and underground. Therefore, they are used in many fields, such as city construction, resource exploration, environmental problems, and transportation. The related technical improvement provides new opportunities for analysis of geological data. The geological models describe the observations in different geological conditions through interpolation and interpretation. At present, it lacks a general model of geological data, which results in much time wasted on rebuilding data structure. Sometimes, geologists recognize visualization relevance by log or overlay of paper plot. This method surely can figure out reliable results, but it is time-consuming and has a heavy load. Especially, man-made error affects modeling precision in the process of study different geological spatial patterns by browsing tables.With the development of computer software, the techniques of interactive demonstration and visualization help overcome the shortcomings of the tables and plots. To manage and store large geological datasets, we propose the node-layer data model called NVDM. Geological object visualization is based on the tri-prism unit. First, preprocess the original borehole data and interpolate the strata into regular grids. Then, connect the grids

“…Currently, three-dimensional (3D) visualizations are widely used in geo-visualization [1,2], urban planning [3], the teaching of various subjects [4,5] and other applications [6]. Many researchers have attempted to improve the 3D models and solve 3D modeling problems such as the limited resources of portable devices for 3D displays [7].…”

An understanding of guidance, which means guiding attention, and constancy, meaning that an area can be perceived for what it is despite environmental changes, of the visual variables related to three-dimensional (3D) symbols is essential to ensure rapid and consistent human perception in 3D visualization. Previous studies have focused on the guidance and constancy of visual variables related to two-dimensional (2D) symbols, but these aspects are not well documented for 3D symbols. In this study, we used eye tracking to analyze the visual guidance from shapes, hues and sizes, and the visual constancy that is related to the shape, color saturation and size of 3D symbols in different locations. Thirty-six subjects (24 females and 12 males) participated in the study. The results indicate that hue and shape provide a high level of visual guidance, whereas guidance from size, a variable that predominantly guides attention in 2D visualization, is much more limited in 3D visualization. Additionally, constancy of shape and saturation are perceived with relatively high accuracy, whereas constancy of size is perceived with only low accuracy. These first empirical studies are intended to pave the way for a more comprehensive user understanding of 3D visualization design.
