Classification value defining the type of hydrographic node. HydroNodeCategoryValue A split in the network captured to indicate a hydrographic point of interest or facility, or a man-made object that affects the network flow. flowConstriction flowConstriction A split in the network captured to indicate a man-made object, that is used to regulate the network flow. flowRegulation flowRegulation A split in the network to indicate where three or more watercourses meet at the same level such as confluences or bifurcations. junction junction The end terminal of a set of one or more interconnected links that does not have any downstream flow. For example sinks or the point where a river enters the sea. outlet outlet The start terminal of a set of one or more interconnected links that has downstream flow. For example springs or collects. source source A location where the real world attribution of a watercourse changes that requires a watercourseLink to be split. pseudo pseudo Node used to connect different networks. NOTE Can be used to connect cross border networks or adjacent networks together. Differs from source / outlet in that in the real world there is an adjacent link that is not present in the dataset supplied.(Source: INSPIRE) boundary oundary
