Zusammenfassung:The invention discloses a surveying and mapping geographic information quality supervision method and system based on CORS big data. The method comprises the following steps: S1, acquiring a plurality of track point data of the CORS big data and a supervised surveying and mapping geographic information project range; s2, clustering a plurality of track point data to simulate the actual situation of the surveying and mapping geographic information project surveying and mapping range; s3, combining the supervised surveying and mapping geographic information project ranges into a quality supervision range graph; s4, carrying out spatial range superposition matching on the actual situation of the simulation surveying and mapping geographic information project measurement range and one map of the quality supervision range; S5, carrying out statistics on the proportion k1 of the number of the matched supervised surveying and mapping geographic information projects in each unit region to the total number of the actu
