摘　　要：超大城市的数字化转型发展对数据质量提出了更高的要求,需要完善数据质量控制环节,提升测绘地理信息数据质量。本文基于上海市新型基础测绘的数据成果,以数据库管理为出发点,开展了数据质量控制方法研究,实现了数据出入库前后数据图层、要素个数、图层属性等方面的一致性比对功能,弥补了数据复核环节的缺失,提高了数据质检的效率。同时,为地理实体在数据库管理流程上的质量控制提供了现实模版。The development of digital transformation of megacities has put forward higher requirements for data quality,and it is necessary to improve the data quality control links to enhance the quality of surveying,mapping and geographic information data.Based on the data results of Shanghai's new fundamental surveying and mapping,this paper carries out the research on data quality control methods with database management as the starting point,realizes the consistency comparison function of data layers,number of elements,layer attributes,etc.before and after data entry and output,makes up for the lack of review links before and after data entry and output and improves the efficiency of data quality control.At the same time,it provides a realistic template for the quality control of geographic entities in the database management process.
