【摘要】 开放式地理信息系统是用以解决各桌面GIS系统之间的信息孤岛现象,达到GIS系统之间的互操作,真正实现地理信息资源的共享而提出的系统解决方案。在OGC(Open GIS Consortium)制定的Open GIS规范下,社会各界都做了很多努力。主要从开放式地理信息系统的结构入手,从地理信息系统开发的关键——空间数据处理出发,阐述国内外较为前沿的关于地理空间数据集成、数据运算以及空间检索引擎的三个技术,最后就目前的应用需求对它的发展提出展望。更多还原

【Abstract】 The open geographic information system was a system solution that proposed for solve the information isolated island phenomenon between various tabletop GIS system’s,achieves interoperability between the GIS system, realized the truly geography information resource’s sharing.Under the Open GIS standard which made by OGC (OpenGlS Consortium),the community has made many efforts.Mainly obtained from the open geographic information system’s structure,embarked from system development’s key-spatial data processing,elaborated the geography spatial data integration,the data operation as well as the space retrieve engine’s 3 technologies that in the domestic and foreign research fronts,and proposed demand to its development the present application at last.更多还原
