摘要
地学数据库的数学基础是统一且分散建立和使用地学数据库的基础,是建立大中型地学信息系统的前提。本文提出了对该数学基础及与之紧密相关的入库变换方法的必须要求,提出了大、中、小3类实用建制方案和相应方法。它们是相互衔接且统一的。
The mathematical foundations of the geographic information data base are essentialto the centrally and separately established geographic information data base and its use.They are also the premise for building large or medium geographic information systems.This paper gives some of requirements for the mathematical basis and relevant transfor-mation methods of inputting data base, and offers practical plans for building large, me-dium and small data bases and the methods involved which are unified and connectedwith one another.
