Research and application of three-dimension electronic sand table for water resource in Three River Source Region

Abstract

In order to improve the water management, decision-making and water efficiency in Three River Source region, 3D-GIS technique was used in water management. At first it confirmed overall design of the structure, and then according to the user specific requirements, to design and expand function of the system. Thus, the secondary development based on World Wind is performed to construct the three-dimensional electronic sand table system of water resources. The results show that the system can provide a comprehensive and intuitive display of topography, morphology and basic geographical information in 3D virtual environment. It demonstrated potential visualization and spatial analysis in combination with different requirements. Therefore it is useful and significant to improve the management, decision-making, sustainable utilization and development of the water resource in the Three Rivers Source region.
