地理省情监测变化统计分析系统的设计与实现——以山东省为例

Design and Implementation of Statistical Analysis System of the Changes in Geographical Situation Monitoring ——Setting Shandong Province as an Example

摘要:

地理省情监测成果是国家重要的数据资源，对其变化内容进行统计分析，是掌握地表自然和人文地理要素变化的基础。伴随山东省地理省情监测工作的不断深入，目前山东省已积累了大量地理省情监测数据。为实现山东省地理省情监测数据的有效管理及科学利用，并综合考虑山东省省级地理信息时空大数据中心的相关要求。该文基于共享文件系统的分布式存储，利用空间统计、任务并行等技术模型，设计了地理省情监测变化统计分析系统，通过对比监测区域内多时态、多版本、多年份数据，发现不同版本数据之间的差异，实现对地理省情数据要素级、地类级变化情况的监测。该文从系统总体设计、关键技术等方面阐述了地理省情监测变化统计分析系统的设计与实现情况。

Abstract:

The provincial geographical situation monitoring results are important data resources of the country. Statistical analysis of the change contents is the basis for mastering the change of the natural and human geographical elements of the surface. At present, geographical situation monitoring work in Shandong province is deepening, and has accumulated a large number of geographical situation monitoring data. In order to realize the effective management and scientific utilization of geographical situation monitoring data in Shandong province, and consider relevant requirements of the provincial geographic information time and space big data center comprehensively, statistical analysis system of geographical situation monitoring changes has been established. Based on the distributed storage of shared file system, by using technical models of spatial statistics and task parallel, statistical analysis system of the change of geographical situation monitoring has been designed. By comparing the multi temporal, multi version and multi-year data in the monitoring area, the differences between different versions of the data have been found, and the change of the element level and the category level of geographical situation data has been monitored. From the aspects of the overall design, key technologies, system design and implementation, design and implementation of statistical analysis system of the change of geographical situation monitoring have been introduced.
