面向GIS的铁路地籍数据库构建

Construction of GIS Based Railway Cadastral Database

铁路地籍数据库要求实现图形、属性数据的统一管理,数据库按自底向上的原则可划分为:地理基础数据、部门应用数据和统计决策数据,由于铁路地籍数据复杂、来源广泛,存在时态性,因此在数据库构建时必须加以考虑。本文以武汉铁路地籍数据库为例对铁路地籍数据库的整体构建进行了分析和阐述。

The railway cadastral database demands realization of uniform management of graphic and attribute data. The geographic data, department using data and decision-making data constitute the database from the bottom to the top. Therefore, the construction of railway cadastral database must be considered its temporal attribute and complexity. To this end, this paper takes Wuhan railway cadastral database as an example to discuss the construction of GIS based railway cadastral management.
