GeoML^(TM)——地理空间信息共享和互操作模式研究

GeoML^(TM)-Research on Geospatial Information Sharing and Interoperation Mode

数字地球为下一代全球信息基础设施建设展示了美好的前景 ,而研究地理空间信息共享与互操作模式正在成为数字地球关键技术的前沿。基于 Open GIS规范和 XML 标准 ,提出了基于 Internet的地理空间对象标识语言Geo MLTM,探讨了可实现在 Internet上传输显示电子地图的 Geo ML 标准规范内容 ,并具体设计和试验了可在Internet上运行的该标准规范的原型系统 ,初步达到了地理空间信息在 Internet/ Intranet上的发布、共享和互操作的目的。

Digital Earth shows great prospects for next generation of Global Information Infrastructure, and the research on geospatial information sharing and interoperation is becoming the frontier of key technology of Digital Earth. Based on the OpenGIS standard and the XML standard, Geospatial Object Markup Language - GeoML , which can be used to transmit and display the electronic map on Internet, has been proposed in this paper, the content of GeoML standard has been detailed. Also the prototype system of this standard has been designed and implemented. And the publishing, sharing and interoperation of geospatial information on Internet/Intranet have been come into true.
