| Abstract: | Fundamental Geographic Information System(FGIS)is the foundation of the digital city spatial information public platform.The system data is collected through the process of encoding and inputting to the database.To ensure the correctness of the data,it is necessary to have the data quality control.Through checking the various multiple-scale types of data in FGIS,the identified problems were classified and analyzed.This paper studied the data quality control of the FGIS,and the results indicated that this co... |
