Abstract
Based on the daily management of water conservancy projects in large basin, one of very effective methods is to use the three-dimensional (3D) geographic information system (GIS), which can greatly improve efficiency and cut down the costs resulted from the large area, complicated situation of terrain, and the higher overhead expenses. However, the most frustrating barriers to the widespread use of 3D GIS is the additional difficulty in 3D navigation. The previous research on 3D GIS is reviewed at these aspects of various domains including precision agriculture and digital river. In order to solve the problem, a holistic resolve treated longitude and latitude as a link between 2D and 3D GIS application to achieve the parameters of a link each other, which is designed according to the actual characteristics of basin simulation system construction based upon a uniform programming framework. This method not only achieves the real-time navigation of virtual 3D geographical scenes but also makes it mapping the geographical coordinates in 2D navigation map and 3D GIS application one. And become real in a basin simulation system too. In this paper, its fundamental idea, implementation techniques and application analysis of the Tarim river simulation system as a case are discussed. Presently, it has been applied in simulation management of the Tarim river basin and shows high facility and efficiency.
