网格环境下的三维空间数据互操作方法研究
Method for 3D Spatial Data Interoperability Based on Grid
-
摘要: 探讨了一种在网格环境下的三维空间数据互操作方法,提出了基于SOAP(simple object access protocol)消息、以图层为单位的三维空间数据表达方法,通过解析SOAP消息便可得到符合GML规范的二维矢量数据、属性数据、纹理及模型数据,方便软件之间的数据交换和互操作。最后通过实验验证了该方法的可行性。Abstract: This paper puts forward an expression method for 3D spatial data, which is on the basis of simple object access protocol (SOAP) message and map layer unit. Parsing the SOAP message, users can acquire the 2D data according to GML criterion, attribute data, texture data. This method can make data exchange and interoperability convenient between software or GIS system.
