Digital River Network (DRN) - River Centerline

This layer was produced as part of the Northland DRN dataset. Over 400 river centrelines were digitised along major waterways with wider channels and used as burn lines in the Hydro enforced DEM, to ensure that the DRN streamlines were delineated down the centre of the river.
