GIS中空间数据管理方式探讨

Analysis of Management of Spatial Data

数据是GIS管理的重点。随着GIS的发展,影像数据、DEM数据等栅格数据将起到越来越大的作用,因此实现多源GIS数据的无缝集成就十分必要。由于其海量和非结构化等特征,实体对象层次模型、群集多服务器体系被提出用以集成并实施高效的空间数据管理。与此同时网格技术给GIS的数据管理带来了新的思路。

Data is very important for GIS management. With the development of GIS, image data and DEM data are becoming more and more important, so it is necessary to seamlessly integrate multi - source GIS data. Because it＇ s massive and unstructured, Feature -Oriented Object Level （FOOL） and Multi -servers cluster system are used to integrate and manage spatial data effectively. Also, grid technology gives a new way to manage GIS data.
