| 摘 要： | 以环境背景数据为研究对象,通过对语义时间、存储格式、记载介质、负责机构、专题信息等属性特征的分析,提出完整的环境背景数据概念;强调环境背景数据的分类编码,应侧重环境背景数据的发现,并着重讨论分类编码的贯彻实施应以元数据为标准载体,在统一的环境背景数据分类编码无法确定时,利用核心元数据中的关键字字段实现分类编码的间接引用,确保元数据标准对不同系列分类编码的兼容并包。

| Abstract: | Classification and coding of environment background data is studied in this paper and the main conclusions are as follows: Environment background data is the object of study, based on the integrated research of attribute characteristics of geographic base, semantic time, storage format, record medium, responsible institution and thematic information, the integrated concept of environment background data is put forward. In the Land System Science supported by Geoinformatics, the classification and coding of environment background data should emphasize discovering environment background data from macroscopic view and the classification and coding of environment background data means "integration is soul, classification is for application". In the course of implementation of geographical data-metadata, metadata should be the criterion carrier of classification and coding. Before the uniform classification and coding is ascertained, the |
