Abstract:

GF-1 satellite, which can provide high-resolution earth observation information, is one of the major members in the high-resolution earth observation system of China.In this study, Hefei city was selected as a case study area.Based on the two GF-1 images at late-May and early-August in 2017, the remote-sensing estimation model for the area of single-season rice was built using the variations of characteristics for different vegetation covers and the blue shift information of rice at maturity.Then, the planting area of the single-season rice in Hefei was estimated based on the model.The estimation accuracy was 93.2%, which were validated by the planting area in the field survey.While the accuracy of estimation of the single-season rice area using the method of the confusion matrix and the Kappa coefficient were 83.7% and 0.84, respectively.In summary, it is feasible that the single-season rice area can be estimated by the remote-sensing model constructed in this study.
