| 摘 要： | GIS二次开发中通常使用的GIS组件方法,大多受到开发商限制或组件提供的扩展接口不能满足系统功能需求的限制.在青藏铁路地理信息系统中为满足应用需求,采用了"IDL C# ArcS-DE"的开发模式,将IDL集成到青藏铁路地理信息系统的体系结构中,并利用IDL实现了GIS的功能.最后阐述了利用IDL进行时态钻孔数据分析、处理及可视化过程和冻土模型输出结果的可视化过程.

| Abstract: | Component technique is generally used in second development in GIS.However,GIS components used in traditional GIS is restricted by provider or can not meet the requirement of system function.In order to meet the application requirement of the Qinghai-Tibet Geographic Information System(QZGIS),"IDL C# ArcSDE" pattern was adopted to develop the system.Interactive Data Language(IDL),which is an important programming language in visualization of scientific computing,was applied to the system structure of QZGIS,in which function of GIS is implemented.According to the study of traditional software "three layer" structure and GIS software standard developed by OGC(OpenGIS Consortium),a new GIS system structure was developed,which has some new features such as data analyzing,image processing and project conversion toolkit.The application of IDL to temporal drill data analysis and visualization is depicted,and the modeling result is displayed. |
