S-101与S-57分类编码对比分析(三):复杂结构

Contrastive Analysis of Classification and Coding Between S-101 and S-57,Part Ⅲ: Complex Structure

地理要素的分类编码是人类认知地理信息世界的成果,也是人类对地理信息世界再认知的入口和关键。在海洋地理信息领域,S-101数据标准即将替代现行S-57 ENC标准,分类编码方案也将会相应改变。从复杂要素、复杂属性两方面内容,对新旧两套分类编码进行对比分析,为涉海人员消化吸收新标准提供一定的参考。

The classification and coding is the achievement in the geography cognition field,as well as the entry and key to the re-cognition of the geographic information world. In the field of the marine geographic information, S-101 data standard is about to replace the current S-57 standard,which brings on the change of classification and coding scheme accordingly.The contrastive analysis of the two versions of classification and coding,from two aspects of complex features and complex attribute,is carried on in the paper,which provides an important reference for maritime-related people.
