Data for: On the merging of optical and SAR satellite imagery for surface water mapping applications

Data on the optical-SAR data fusion for surface water mapping. "sar-optical-timeseries.xlsx" is the time series data with two sheets, one being the SAR timeseries and the other being the optical time series. "hydraCase_Nov_sar.tif" is a 2-band Geotiff file of the water extraction methods on SAR data with the first band being the water index and the second band being the extracted water. "hydraCase_nov_opt.tif" is the same as "hydraCase_Nov_sar.tif" but for the optical sensor.本数据集用于地表水制图的光学-合成孔径雷达（SAR）数据融合研究。其中，"sar-optical-timeseries.xlsx"为时序数据集，包含两个工作表，分别存储合成孔径雷达时序数据与光学时序数据。"hydraCase_Nov_sar.tif"为2波段地理标记图像（GeoTIFF）文件，对应基于SAR数据的地表水提取结果，其第一波段为水体指数，第二波段为已提取的水体数据。"hydraCase_nov_opt.tif"的文件结构与"hydraCase_Nov_sar.tif"完全一致，仅对应光学传感器的相关数据。
