Using remote sensing software such as GIS, ENVI, etc., the required images are fine-corrected to ensure that the error of adjacent images is less than one pixel, and then digitized, spatial and attribute data are extracted, sorted, and trimmed.
Data sets are quality controlled through rigorous manual review.
