面向对象的地理空间信息元数据标准研制方法

Developing Metadata Standard for Geospatial Information with Object-Oriented Method

摘要: 论述了地理空间信息元数据中的对象的特质,构建了地理空间信息元数据对象模型,提出了结合面向对象中的对象操作和面向对象软件工程的地理空间信息元数据标准的研制方法。并以此为指导,实施了《水利地理空间信息元数据标准》的研制,有效解决了研制地理空间信息元数据标准时在分工合作、进度控制和所开发标准在兼容性、重用性等方面存在的问题。

Abstract: The characteristics of geospatial metadata is discussed,the object hypostases of geospatial metadata is anatomized,and object model of geospatial metadata is constructed.Based on this,how to develop geospatial metadata standard with object-oriented method is presented the approaches are designed in detail,and the method to develop metadata standard for geospatial information of water resources is applied.
