| 摘 要： | 地理信息系统空间数据的异源性问题是当前系统应用普遍存在的问题。如何解决异源性问题在集成应用中的语义、编码的统一性和正确性是地理信息描述的关键。本文对目前跨行业地理信息异源空间数据集成在各行业中的应用现状进行了对比分析,并试图引入“中间库”等思想,对实现地理信息平台搭建过程中实际存在的空间异源数据集成问题做了初步探讨。

| Abstract: | It is existing at large in GIS that the spatial data is from multi-trades. It is the key factor that the semantic problem, the oneness and validity of coding is well resolved about the problem that geo-information is exactly expressed. In this paper, the author discussed how the integration of the data from different trades was applied to some trades at present,and tried to do some work in this problem by some means that the middle-base tapes part in the construction of the system. |
