Research and Implementation of Database Quality Control Methods for New Fundamental Surveying and Mapping
The development of digital transformation of megacities has put forward higher requirements for data quality,and it is neces-sary 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 meth-ods 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 out-put and improves the efficiency of data quality control.At the same time,it provides a realistic template for the quality control of geo-graphic entities in the database management process.
