土地年度变更调查更新中内业数据质量检查方法

Methods for Checking the Quality of Office Data in the Annual Land Change Survey and Update Project Source

土地变更调查更新工作时间紧,任务重,且质量检查会遇到种类繁多的问题,人工修改效率低下。根据国家检查细则,针对质量检查中常见的问题,结合变更工作流程,利用ArcMap数据库处理软件,定制结构化查询语言(SQL)对土地利用现状数据库进行处理,能够高效完成土地年度变更调查更新工作。结合工作实例,着重讨论了土地变更调查更新工作中内业数据处理时常见的质检错误,相应的处理方法,并形成了可推广的解决方案,为土地年度变更调查更新工作内业数据处理提供技术参考,提高了工作成效。

The land change survey and update work is tight in time,with heavy tasks,and quality inspection may encounter a variety of problems,resulting in low efficiency in manual modification.According to the national inspection regulations,in response to common problems in quality inspection,combined with the change workflow,using the ArcMap database processing software,customizing the Structured Query Language(SQL)to process the land use status database can efficiently complete the annual land change survey and update work.Based on work examples,this paper focuses on discussing common quality inspection errors and coresponding processing methods in the processing of office data in land change survey and update work,and forms a scalable solution.This provides technical reference for the processing of office data in annual land change surveyand updatework,and improves work efficiency.
