【摘要】 提出了一种全新的基于XML无GIS平台支持的国土资源空间数据网络发布与集成体系框架。国土资源空间数据采用基于矢量的全要素数据模型。该模型由XML描述,并由关系型数据库存储,采用SVG与X3D实现其可视化表达与空间操作。对该框架进行了原型实现,构建了一个全国省级国土资源空间数据网络发布与集成环境。更多还原

【Abstract】 A new XML-based network publication and integration framework of spatial data of land resources without GIS platform support is put forward.In this framework,the spatial data of land resources are described by XML based on vector-based full feature data model,and are stored by RDBMS,and the visualization and spatial operation of them are realized by using SVG and X3D.Finally,a prototype system based on this framework is realized,and then a network publication and integration environment of spatial data of countrywide provincial land resources in China is formed.更多还原
