基于Geodatabase的城镇地籍数据库设计

城镇地籍数据库中的数据类型繁多,关系复杂,需要采用良好的空间数据库来管理和维护。依据相关技术规范,基于Geodatabase进行城镇地籍数据库设计。围绕实体类型的划分、要素分类与分层、子类设计、要素属性表和属性域设计、拓扑规则设计、要素数据集设计等进行了详细论述。最后,对本数据库设计方案作了一些相关说明。

Design of town's cadastral database based on Geodatabase

There are such many types of data and complex relations in the town's cadastral database that good spatial database must be needed to manage and maintain them.Following correlated technologies and criteria,the town's cadastral database is designed based on Geodatabase.The paper discusses partitioning entities' type,classifying and delaminating features,designing the subclasses,structure of feature attribute tables,attribute domain,topology rules and feature datasets,and so on.Finally,some commentaries about the database design are included.
