基于GF-1号卫星16米分辨率影像的2016年夏季湖北汤逊湖洪涝灾害洪涝提取数据

2016年6月30日至7月6日，湖北武汉沿江地区等多地突发持续强降雨，引发严重洪水灾害和城市内涝，其中武汉市汤逊湖湖水上涨明显，一度淹没汤逊湖大桥,发生超100年一遇特大洪水。该数据包含了此次洪涝事件的灾前、灾后水体数据与淹没范围数据。

From June 30 to July 6, 2016, multiple areas including the riverside regions of Wuhan, Hubei Province were hit by sudden and sustained heavy rainfall, triggering severe flood disasters and urban waterlogging. Notably, the water level of Tangxun Lake in Wuhan rose significantly, once submerging the Tangxun Lake Bridge, and an extreme flood event with a return period exceeding 100 years occurred. This dataset contains pre-disaster and post-disaster water body data as well as inundation extent data for this flood event.
