摘要

在当前网络环境下

土地利用数据面临实时共享问题。正如XML是Internet上信息表示和数据交换的标准一样

OGC提出的基于XML编码的空间信息表达规范GML

是目前网络中空间数据的交换、共享与互操作的事实标准。依据国家标准GML 3.2.1规范

通过对土地利用要素以及要素之间的关系进行分析

设计了土地利用要素的GML应用模式。根据定义的应用模式

实现了GML实例数据的生成。基于C#语言、文档对象模型(DOM)和XML查询语言(XPath)开发了一个基于GML的土地利用GIS查询系统

该系统实现了GML土地利用数据的显示、浏览和查询等基本功能。基于WFS 1.1.0版本规范设计并发布了一个GML土地利用数据服务。研究和实践表明

GML可以表达土地利用数据

并有利于实现土地利用数据共享。

Abstract

Real-time data sharing is a critical problem for land use data management under current network environment.Just as the XML is the standard criterion of information expression and data interchange for internet

GML

which is based on XML and developed by OGC

is the factual standard of the exchange

sharing and interoperability of spatial data in internet.Based on the national standard of GML 3.2.1

a GML application schema was designed for elements of land-use through the analysis of these elements and the relations among them.Based on GML and combined with C#

DOM and XPath

a inquiry system for land-use data has been developed.Under this system

many fundamental functions can be achieved such as the inquiry

displaying

browsing and publishing of land use data.The results and practice showed that GML can express land-use data better and facilitate the realization of land use data sharing.
