nearest mapped polygon was smallest for the joint classified landscape change product (Sentinel-1 and Sentinel-2 product) and the intersection percentage of the classified change polygons with the two validation datasets was the highest (point dataset: 17.9% and polygon dataset: 63.6%, Table 8)....
From the field survey using GPS the cropland area is found to be 3635Ha which is found closest to the cropland area computed from the Sentinel-2 dataset using SVM. From the Table 2 it can be noted that there is over-classification of cropland area and under classification of non-crop...

将改完的myGraph.xml文件保存,此时我们还需要一个名为processDataset.bat的批处理文档。此文档的百度云盘链接: https://pan.baidu.com/share/init?surl=CGCM5atHILVJGKPHFcGoqA提取码:6x2h 最后一步,进入cmd到存放数据的文件夹下,以笔者输入的命令为例,按下Enter运行后就可在导出路径下看到处理完成的影像。
We randomly eliminated the corresponding proportional observation data from the dataset as the imputation truth-value for evaluating the imputation accuracy. Finally, these data with complete and incomplete patterns were input to the Im-BiLSTM model to perform imputation and classification tasks. We ...
