摘要
WebGIS是当前GIS技术研究的一个热点。本文分析了采用Oracle Spatial作为空间数据库,GML作为传输数据格式开发WebGIS系统的优点,讨论了Oracle Spatial中空间数据的访问方法、GML与Java的数据绑定、GML格式数据的解析等关键技术,最后实现了一个WebGIS系统。本文的研究为集成Oracle Spatial和GML的WebGIS的进一步研究提供了有益参考。
WebGIS is a hot spot in GIS studies nowadays. This paper analyzes the advantages of Oracle Spatial and GML in WebGIS applications, and discusses the key technologies, including the method of accessing data in O-racle Spatial and the method of data binding between GML and Java. It also expatiates on the realization of a WebGIS system. The methods presented by this paper may provide something useful for further studies on combining the use of Oracle Spatial and GML in WebGIS applications.
