地理信息资源建设与维护更新质量检查软件研发

Development of Quality Inspection Software for Geographic Information Resources Construction and Maintenance Update

地理信息资源建设与维护更新项目成果种类繁多、数据量大,质量检查内容繁杂,为了提高项目成果检查效率和成果质量水平,针对地理信息资源建设与维护更新项目的所有成果质量控制关键点、检查内容及计算机程序实现方法,提出“任务”驱动的并行计算架构,并基于ArcGIS Engine平台,开发GM_Master质量检查软件。该软件解决了程序运行过程中线程的安全性及合理的伸缩性、全自动化DOM接边精度检查等开发技术难点问题。实践证明,GM_Master质量检查软件检查准确度和运行效率高,功能全面,可操作性较强,能满足该项目成果检验的需求。

The results of the geographic information resources construction and maintenance update project are various, with large data volume and complex quality inspection contents. In order to improve the efficiency and quality of the project results, this paper proposes a task driven parallel computing architecture for all the key points of results quality control, inspection contents and computer program implementation methods of the geographic information resources construction and maintenance update project, and develops1 GM_Master quality inspection software based on ArcGIS Engine platform. The software solves the development technical difficulties such as thread security and reasonable scalability in the process of program running, and fully automated DOM edge checking.Practice has proved that GM_Master inspection software has high accuracy and efficiency, comprehensive function and strong operability, which can meet the requirements of the project results inspection.
