基于FME的自然资源督察省域研判

Provincial Research and Judgment of Natural Resource Supervision Based on FME

为了快速发现督察区域的疑似问题,需在实地督察前对该区域进行研判分析。因此,介绍了省域研判的内容和关键点以及FME软件在省域研判中的优势,并以2021年北京市土地卫片核查为例,使用FME平台对数据记录达百万级别的13种数据进行叠加分析,结果表明该方法能够显著提高研判效率、保障研判结果存储规范、明显减少技术人员的负担,同时能够对叠加结果实现逻辑判断,快速分析出卫片填报中存在的疑似问题。通过与某区实地督察情况对比,研判提出的重点核查台账包含了该区约45%的问题图斑,表明该方法对实现高效督察和精准督察具有实践意义。

In order to quickly discover suspected problems in the inspection area,it is essential to conduct the research and judgment analysis be-fore the on-site inspection.In this paper,we introduced the content and key points of provincial research and judgment and the advantages of FME software in provincial research and judgment.Taking the Beijing land satellite photo verification in 2021 for example,we used the FME platform to carry out overlay analysis 13 kinds of data with millions of data.The results show that this method can significantly improve the effi-ciency of research and judgment,ensure the storage normalization,and clearly reduce the burden on technical personnel.At the same time,this method can implement logical judgments on the superimposed results and quickly analyze suspected problems in the submission of satellite films.By comparing with the situation of on-site inspections in a certain district,the key inspection ledger proposed by the research and judgment contains about 45%of the problem maps in this area,indicating that this method has practical significance for efficient and precise inspections.
