Abstract :
Toward the problems existing in the fragmented land parcel of autumn crops in china and the low resolution of MODIS and difficulty in obtaining high-quality Landsat data, spatial and temporal fusion technology with MODIS and Landsat data is used to generate high-spatial-temporal resolution time series data. Then, combine the data generated and use SVM method to identify autumn crops and then determine which data to be the best choice for autumn crop identification. The results show the overall accuracy of paddy and corn with red data is the highest up to 87.47% and the user´s accuracy of paddy and corn of NDVI data reached 84.91% and 75.36%, respectively. Overall it is feasible to use the high-spatial-temporal resolution time series data generated to identify autumn crops.
