VGE geographic knowledge refers to the abstract and repeatable geo-information which is related to the geo-science problem, geographical phenomena and geographical laws supported by VGE. That includes expert experiences, evolution rule, simulation processes and prediction results in VGE. This paper proposes a conceptual framework for VGE knowledge engineering in order to effectively manage and ...

Two methods of grid based and image based modeling were put forward respectively to represent the landform of watersheds on the Loess Plateau, China. Many kinds of spatial data such as Digital Elevation Model (DEM), Remote Sensing (RS) images, and photos are utilized to establish the digital 3-D terrains of watersheds on the Loess Plateau, which provides 3-D virtual geographic environments for ...

The integration of high dimensional geo-visualization, geo-data management, geo-process modeling and computation, geospatial analysis, and geo-collaboration is a trend in GIScience. The technical platform that matches the trend forms a new framework unlike that of GIS and is conceptualized in this paper as a collaborative virtual geographic environment (CVGE). This paper focuses on two key issu...

background: multidrug resistant enterobacteriaceae which was confined to the hospital environments is now emerging in the domestic food related environments as well. the main objective of the present study was to investigate the prevalence of antibiotic resistant enterobacteriaceae in the domestic food related environments.  methods: resistance to ampicillin, chloramphenicol, ciprofloxacin, gen...

Virtual geographic environments (VGEs) have been regarded as an important new means of simulating, analyzing, and understanding complex geological processes. Plants and light are major components of the geographic environment. Light is a critical factor that affects ecological systems. In this study, we focused on simulating light transmission and distribution within a three-dimensional plant c...

living in satisfying urban environments is important for an individual’s well-being. in order to create such environments, planners, designers, and policy makers need to understand the structures that cause residents to feel satisfied with their environments. this paper focuses on the perceived quality of urban residential environments: dwellings and neighborhoods. first, literature review was ...

The 3D complex building models are commonly of massive data, detailed appearance and sophisticated topology. The LOD modelling and real-time visualization of such models have hampered the wider applications of Virtual Geographic Environments. Aimed at the drawback of traditional simplification methods—difficult to locate the components, primitives that have to be decimated, this paper proposes ...

microfacies and depositional environments interpretation of asmari and jahrum were studied in boreholes 2, 10 and 11 in gol- khari oil field. based on petrographic criteria, fauna assemblages, biofacies and sedimentary textures, 21 carbonate microfacies and 3 non- carbonate petrofacies were recognized. these microfacies were deposited in distinct depositional environments including tidal flat, ...

decreasing qualitative aspects of residential environments is a real problem in recent public housing of kerman. this article is concentrated on surveying the impact of in-between spaces on residential environments quality (req), to evaluate different kinds of it and to determine interrelation of two main components: residents individual characteristics and characteristics of in-between spaces....
