摘要
分析了 ESRI的组件式 GIS产品 Map Objects组织和管理空间数据的方法 ,对其在多图层、多专题、分布式存储的空间数据的管理中所遇到的问题和不足进行了探讨 ,提出了一种解决思路。同时建立了一种改进的模型并给出了相应的算法 ,在实际的应用中取得了较好的效果。
The method about orgnizing and managing spatial data ,provided by MapObjects which is a kind of product of ESRI, is analized,at the same time the problems and disadvantages met when managing multi-layer,multi-theme spatial data saved distributedly is discussed,and then an available method is provided in this article.Furthermore,an improved model as well as algorithm is built,which has acquired a good purpose in applying.
