A 1km resolution dataset of planting area of three staple crops in China during 2009-2015 V2（ChinaCropArea1kmV2）
Listed in ScienceDB
The dataset includes 21 files of the planting area of rice, maize and wheat in China from 2009 to 2015 in TIF format, one file for each crop per year.
Description
The pixels with values of 2 and 4 in the rice file represent the planting grids of one-season rice and early-late rice, respectively. The pixels with values of 3 and 6 in the maize file represent the planting grids of summer maize and spring maize respectively.
The pixels with values of 5 and 7 in the wheat file represent the planting grids of winter wheat and spring wheat, respectively. The spatial resolution is 1km. The "Asia North Albers Equal Area Conic" coordinate system was used for the projection.
