1:25万赤布张错幅区域地质图空间数据库建设方法与意义

The Build of Spatial Database for 1:250000 Chibuzhangcuo Regional Geology Map:Method and Significance

1:25万赤布张错幅区域地质图空间数据库建设是依据《数字地质图空间数据库标准》,将传统填图方法完成的1:25万区调图幅在当前空间数据库模型的典型代表地理数据库模型上建立的。该模型以研究实体为对象,把对象分为基本要素类、综合要素类和对象类,通过组成地质图基本要素类和对象类出发,处理和把握存储与组织的关系,采用关联、依赖、组合和继承来描述对象之间的关系规则来构成新的关联集合的技术,增强了数据库服务能力。

The build of spatial database for 1：250 000 Chibuzhangcuo regional geology map is based on The standard for spatial database in digital geological map,which is used for transform the traditional geological map to new geographical database-based digital geology map.The new modal makes the research entities to be object,and subdivide the object into basic feature class,synthesis feature class and object class.The basic feature class and object class which are the main elements of geological map are used for deal with the relationship between memory and texture.The associate,depend upon,assembled and inherit of those objects makes the relationship rules for the new spatial database building technology,which makes the new spatial database more powerful for the future service.
