Description

bothDirections

Water flows in both directions along the watercourse.

inDirection

Water flows in the same direction as the order of the coordinate vertices.

inOppositeDirection

Water flows in the opposite direction to the order of the coordinate vertices.

Where the flow direction has not been determined, this attribute is set to null and a ‘nilReason’ is given.

Where the value of nilReason is set to ‘unknown’, then the flow direction is not known to Ordnance Survey. A correct value may exist, but the methods employed by Ordnance Survey to date have not facilitated capture.
Where the value of nilReason is set to ‘missing’, then the flow can be considered indiscernible. Ordnance Survey has attempted to identify the flow on the ground, but no flow has been determined.
