DBGT10K — Watercourse wet area (Archi)

It describes the area, part of an engraved river bed, with the presence of water, detected at the time of photorestitution. The area of permanent islands shall be excluded from the surface of the wet area containing them. See: Distribution of wet areas according to the watercourse and their closure with fictitious sections See: Example of Bathed Area The “Based Area” must have continuity characteristics even in the presence of artifacts that overlap it, and must be closed by a fictitious trait at: — the confluence of a watercourse: — in another stream — in a body of water — in an artificial reservoir — of the intersection with the sea coastline See: Example of wet area of confluent watercourses

本数据集描述的是一处刻蚀河床（engraved river bed）区域，区域内存在水体，且该区域于影像复原阶段被探测得出。包含永久性岛屿的水域，需将岛屿面积从所属水域的表面范围中扣除。参见：基于河道的水域分布及其虚拟断面闭合方法；参见：水域示例。基准区域（Based Area）需具备连续性特征，即便存在与其重叠的影像伪影，且需在以下场景处通过虚拟界线进行闭合：——河道交汇处：——汇入其他溪流时——汇入自然水体时——汇入人工水库时——与海洋海岸线相交时。参见：汇流水域示例。
