Comprehensive validation and refinement of cropland maps in southwest China

The datasets stored in the repository includes: (1) The albers equal conic area projected coordinate system (PCS) applied to China area, (2) ten existing cropland maps in southwestern China with the spatial resolution in 1-m ~ 30-m as well as (3) refined cropland maps (CroplandSyn) based on the harmonizing of consistency. All the raster files are with the albers PCS and the pyramid file in .ovr format is also attached for a quicker loading for software. (4) Validation sample sets in shapefile format for southwestern China cropland maps. (5) Javascript codes run by Google Earth Engine (GEE) to pre-process the cropland maps.
