Establishment of remote sensing monitoring method and standard on winter planting crops: A case study in Leizhou Peninsula of south China

The winter crop planting can bring increased income for peasants, but also improve the soil quality by rotation system. So, the planting area monitoring remote sensing of winter crops have been an important work for agriculture planting structure statistic, management and decision in south China. At present the cloudy and rainy weather is a very serious issue for remote sensing of winter crops in south China. So grasping the phenology of winter crops is of vital significance to establishment of remote sensing monitoring method and standard on winter crops. In order to form the remote sensing monitor method and standard to extract the planting area of winter crops, the paddy field and dryland based multi-temporal spectral angle remote sensing approach and standard were put forward, that includes five Landsat OLI image spectra and corresponding NDVI to compose the reference spectra of 40 bands during autumn and winter season. The mapping result in 12 experimental plots showed that the remote sensing monitoring standard performed well for retrieving the winter planting crops in Guangdong province of south China.
