摘要
空间数据的集成是地理信息系统中的一个重要课题,针对多个存放不同类型地理数据的空间数据库,提出了一个基于空间元数据的多类型空间数据库集成方案,把各种类型的空间数据库集成为一个有机的整体,以地图作为地理数据分发和管理的单位,同时还可保持已有空间数据库的自治性,给出了方案的具体实现。
The integrate of spatial data is an important subject of geographic information system, Because of spatial databases which store different type of Geo-spatial data, many difficulties were brought for user. In order to solve the problem, an integrated data model of multi-type spatial databases was given, an organic whole of all kinds of spatial databases was integrated, the map was regarded as the unit of geographical data distributing and management, and autonomy nature could be kept.
