摘要
以房屋土地地理信息系统 (GIS)中的地籍图形数据为例 ,探讨了基于地理标识语言 (GML)规范的空间要素描述 ,包括其数据描述结构和GML文档 ,并基于JAVA语言、文档对象模型和XML语言接口协议 (SAX)实现了一个基于GML的地籍GIS查询系统 。
Taking cadastral graphic data as example, spatial feature definition and description based on geography markup language in geography information system(GIS) is proposed.A schema defining the geography markup language (GML) structure is presented,in which cadastral features are described as CityModel,StreetMoel,BlockModel,LandModel and BuildingModel,and the relationships between these features are defined as CityMember, StreetMember, BlockMember and Landmember.Based on this,GML document creations are discussed in detail to describe the cadastral features.And a test system used to browse and query cadastral information is developed based on JAVA language,document object model(DOM) and simple application interface for XML (SAX).The feasibility of the proposed spatial feature description based on GML is tested through the system.
