| Abstract: | Wudu district is located at the southeast of Gansu province.It is the only reaches of Changjiang river in Gansu.Wudu is one of the cities which suffering from debris flow most severely in China.This study identified the debris flow by using the eye interpretation and Man-computer interactive interpretation.It constructed the 3D view of this region,and realized the navigation of the 3D view.Finally,by using the powerful functions of GIS,the study carried out the design of the geodatabase and the management o... |
