In Three Gorges reservoir area of China, 3D visualization and analysis functions are widely needed in many works of geological hazard survey, inspection, pre-warning and treatment of local landslides and collapses, and decision making for emergency response. However, current 2D or 2.5D GIS system cannot satisfy all these kinds of requirements and a 3D visualization and analysis system of geological...
Combining system dynamics (SD) and the principle of hydrocarbon migration-accumulation (HMA), on the basis of corner point grid model (CPGM), this paper simulated HMA of Dongying depression maturing exploratory area adopting the labyrinth migration mode. The simulation results meet the needs of practical exploration. Thus, a reliable tool is provided for the immature exploratory area while decreasing...
Becoming development trend of GIS, three-dimensional visualization makes the amount of spatial data grown inevitably. Therefore, the study on storage and management of massive three-dimensional geospatial data is necessary and significant. The C/S framework, which consists of massive three-dimensional geospatial database for server and a large number of low-profile PC for clients, has become a basic...
