Research on Quality Control Method of Fundamental Geographic Conditions Monitoring Data
Geographic conditions monitoring plays an important role in natural resource investigation and statistics,and is an important way to realize a comprehensive understanding of the basic national conditions.Based on fundamental geographic conditions monitoring project in 2020,combined with the production practice experience,this paper discusses the production process and quality inspection methods in geographic conditions monitoring.At the same time,the typical quality problems in the production process of geographic conditions monitoring are discussed around the use of data sources,data update and collection and attribute assignment.Finally,ac-cording to the quality problems existing in the geographic conditions monitoring,the corresponding quality control and improvement schemes are put forward,which provides a reference for the in-depth and orderly development of geographic conditions and control methods in the future.
