REC watersheds v2.5 (River Environment Classification)
The REC has been used to classify all the rivers of New Zealand at a 1:50,000 mapping scale. The area classified comprises 267,000 km2 and 426,000 km of river network. The important attributes are nzsegment (primary key), which can be used to join the watershed polygons to the river network, and the old_nzreach (which can be used to retrieve values from REC1 river classification, and other previously calculated properties). The shape_area gives the area of the watershed in meters squared.
