可靠性地理国情动态监测的理论与关键技术探讨

Key theories and technologies on reliable dynamic monitoring for national geographical state

地理国情是一个国家的社会性质、政治、经济、文化等方面的空间化、可视化的国情信息.可靠的地理国情关系到国家重大决策的正确性.地理国情监测是中国2011年制定的一个新的国家发展方向,迫切需要提出相应的技术支撑体系.本文分析了可靠性地理国情动态监测的基本概念,提出了地理国情动态监测的总体研究框架,探讨了可靠性地理国情动态监测的可靠性分析与质量控制、时空动态建模等理论和方法,研究了空天地一体化的地理国情监测体系构建、可靠性非空间信息的空间化表达、可靠性地理国情动态变化检测、地理国情时空数据动态更新与一致性维护、地理国情动态监测数据的可靠性综合分析、地理国情动态监测的可靠性空间数据挖掘、地理国情监测辅助决策建模、可靠性地理国情监测的云计算框架、地理国情可视化技术、地理国情监测中的GNSS和手持终端技术、可靠性地理国情总动态评估技术等关键技术,并总结了地理国情动态监测需要解决的核心问题.

National geographical state is on spatial-related national state regarding social nature, politics, economy and culture of a nation. The reliability of national geographical state is a crucial issue which will affect the correctness of a national strategic decision and planning. Reliable monitoring of national geographical state is thus a new research direction scientifically and with an urgent demand by the country. In this paper, the research on reliable dynamic monitoring of national geographical state is proposed, including basic concepts, general research framework, key technologies and theories, and core problems to be solved. The proposed key technologies and theories for reliable geographical state monitoring include reliable analysis and quality control of dynamic monitoring, spatial-temporal dynamic modeling, integrated space-air-ground monitoring system, geographical grid-based representation of non-spatial data, change detection, dynamic update and consistency maintenance of spatial-temporal data, reliable analysis, reliable data mining, reliable decision-making, cloud computing framework, geo-visualization and techniques of GNSS and handheld devices for monitoring data capture.
