摘  要:
在以往水土流失应用系统中,查询分析主要建立在二维地理信息系统的基础上。主要研究在三维数据模型基础上实现查询,利用层次细节水平(LOD)方法以及海量数据动态调度方法解决海量数据的提取、调度,以ArcSDE作为空间数据引擎来管理和高效访问空间数据,通过GIS组件实现三维数据的可视化。以此应用到湖北省水土保持综合查询系统中,结果表明系统能在三维模型基础上有效地对全省水土流失相关信息的查询统计。

摘  要:
In traditional soil erosion system,query and analysis were based on two dimensional(2D)Geographie Information Sys- tem(GIS).Query and analysis based on three dimensional(3D)data mode and data visualization were introduced.The key is- sues,levels of detail(LOD)method,huge data scheduling,ArcGis spatial database engine(ArcSDE)for data approaching,ac- cessing and management were described and applied to the soil and water conservation query system of Hubei Province.The re- sult showed that the system could meet the need of query and analysis of soil erosion information about the whole province.
