Calculate the absolute difference between the reconstructed RSEI model and the original RSEI model, where (a), (d), and (g) represent the original RSEI for the years 2000, 2012, and 2020, respectively, (b), (e), (h) represent the reconstructed RSEI index. The map is designed using ArcGIS Pro V2.5 software provided by the ESRI website (https://www.esri.com/en-us/arcgis/products/arcgis-pro/overview). Among them, the RSEI for the years 2000, 2012, and 2020 is calculated using the Landsat 5, 7, and 8 surface reflectance products provided by the USGS (https://www.usgs.gov). These products are freely available on Google Earth Engine (GEE) (https://earthengine.google.com), and the calculation process is also conducted within GEE.
