Land Water Transition Zone Change Detection - Transition Maps between two dates - WQeMS raster products

Within this dataset, land water transition zone maps, which indicate the land-water transition between two instances in time, of the Polyphytos open surface water reservoir in Greece and Giaretta reservoir in Italy, are available in GeoTIFF raster format. The maps depict the transition zones by indicating the change of the pixel status from non-inundated to inundated and vice versa between two provided dates. They were generated by the Land Water Transition Zone Change Detection service of the WQeMS project. Each raster file in the dataset is named according to the water body and the two dates during which the processing was performed. Copernicus Sentinel-2 data was utilized for the generation of the inundation maps on the two dates.本数据集收录了希腊Polyphytos露天地表水库与意大利Giaretta水库的水陆过渡带（Land Water Transition Zone）地图，此类地图用于表征两个时间节点间的水陆过渡变化，数据以GeoTIFF（GeoTIFF）栅格格式存储。此类地图通过标注两个指定日期间像素状态从非淹没转为淹没或反之的变化，来描绘水陆过渡带。本数据集的地图由WQeMS项目的水陆过渡带变化检测服务生成。数据集中的每个栅格文件均根据其所对应的水体以及处理所使用的两个日期进行命名。两张对应日期的淹没地图均基于哥白尼哨兵2号（Copernicus Sentinel-2）数据生成。
