Map symbols play a big role in emergency mapping applications as the spatial technology increasingly becomes very important for decision makers to make judgments in emergency management. Badly defined map symbols may lead many difficulties in collaborative emergency management. Therefore, it is necessary to investigate the methodology of defining the map symbols in a comprehensive and standardized...
Increasing numbers of different disasters have caused huge damages to many countries all over the world, and therefore it brings big challenges to the disaster management. Mapping technologies of cartography and GIS are often used to assist the disaster management, such as the visualization of the disaster situations, in order to analyze the affected results of disasters, efficiently deploy the accurate...
An integrated strategy coupling GIS with two-dimension hydrodynamic model is explored to simulate the flooding inundation in the upper reaches of Huangpu River. DEM data, hydraulic engineering map and other available geospatial data are used and aid to generate the computational grid, while, some treatments of interior and exterior boundary conditions, and calculations of variable resistance terms...
In recent years, the deterioration, eutrophication and other water pollution problems are increasingly serious in Taihu lake, which have become new constraints of regional development. Based on GIS, most applications of Taihu lake relevant research were mainly emphasized on the traditional GIS data management and analysis, which lacked three-dimensional water pollution dynamic process simulation....
The Taihu Lake water is the lifelines of economic and social development of the Taihu Lake valley. In recent years, the deterioration, eutrophication and other water pollution problems are increasingly serious, which have become new constraints of regional development. The cure of eutrophication and pollution of Taihu Lake is imminent. At the same time, 3D geo-science modeling and 3D dynamic process...
