Summer Rainfall Crops

Data on crop types and field extents were obtained from DAFF for central provinces (Free State, Gauteng, Mpumalanga, North West). These were combined into a single data set after normalising the crop type descriptions (there were slight variations in description between the data sets).中部省份（自由邦省、豪登省、普马兰加省、西北省）的作物类型与田块范围数据均采自农业、渔业与林业部（DAFF）。在对作物类型描述进行标准化处理后（各数据集间的描述存在细微差异），将上述数据整合为单一数据集。
