HydroNodeCategoryValue

Code list: HydroNodeCategoryValue

Classification value defining the type of hydrographic node.

Code	Description
flowConstriction	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. This attribute is not manifested in this release of the data; however, it will be utilised in future data updates.
flowRegulation	A split in the network captured to indicate a man-made object that is used to regulate the network flow. This value is not currently supplied.
junction	A split in the network to indicate where three or more WatercourseLink features meet at the same level, for example, confluences or bifurcations.
Outlet	The end terminal of a set of one or more interconnected links that does not have any downstream flow, for example, where a watercourse sinks into the ground or the point where a river enters the sea.
Source	The start terminal of a set of one or more interconnected links that has downstream flow, for example, springs or collects.
Pseudo	A location where the real-world attribution of a watercourse changes that requires a WatercourseLink to be split.
boundary	HydroNode 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.

Where the hydroNodeCategory has not been determined, this attribute is set to null and the value of nilReason is set to ‘unknown’.
