| Abstract: | Hydrological systematic data organization in drainage area for the requirement of capturing, updating, managing and applying of spatial information about drainage area data supplies experience for drainage area data establishment and speeding drainage informatizationby performing key technologies research, developing internet applications and integrating system. This article gives a brief introduction about necessity, feasibility and technological sustainment for drainage area hydrological system construction and a kind of view organizing drainage area data using Geodatabase model. Based on Geodatabase, a drainage database is established by integrating all factors in the drainage area and their interaction is defined. Especially, an emphasis research has been enforced on water net, hydrological data organization and its modeling.The technological procedures put forward supply reference and new idea for drainage area research and construction. |
