Abstract

The present invention discloses a method and system for real-time data processing in the process of national land space planning. The processing method includes calculating and obtaining a complete data clarity index, screening and sorting the complete remote sensing images of the national land space to be measured, and constructing a first complete data set; calculating and obtaining a grid data clarity index, screening grid images of the same grid number according to the grid data clarity index, and determining each grid image that generates a clear national land image; calculating and obtaining a sub-region data clarity index; obtaining a real-time data quality index within a day, and calculating and obtaining the time when the collected data quality reaches the standard. The present invention can monitor the quality status of data collection in real time, adjust the data collection strategy in time according to the data quality status, optimize resource allocation, and improve data collection efficiency.
