城市公用地理信息分类与代码

The Category Classification and Coding Systems of Urban Public-Geographical Information

就城市公用地理信息的若干问题进行了探讨，重点阐述城市公用地理信息应包含的对象、范围、内容和特点。根据城市公用地理信息具有类型多、系统复杂、重复性多、关联度强、动态变化性强的特点，建立了信息分类的原则和４级分类体系，并按确立的规则对其进行分类和编码，在此基础上建立起其指标体系分类和代码表以及编码方案，共包括５个门类、４９个大类、２４７个中类和５３１个小类以及它们的编码体系。为实现利用现代化的科学管理手段对城市地理信息进行有效地采集、处理、查询、检索、分析和管理，并实现城市信息共享奠定了基础。

This paper discussed some key matters of urban public-geographical information standardization. It mainly analyzed the object and scope of urban public-geographical information that represents the characteristics of multi types, complex, connectivity and dynamics. Based on that, the rules for classification and code representation are constructed. According to such regulations to form category index system, and code sheet as well as coding system, which will provides a base for the fully using of intelligent management methodologies, to collect, deal, query, index, analyze, manage and share the urban public-geographical information.
