NZ Topo - object class river_cl

This page describe the river_cl object class used to represent objects in the NZTopo topographic database.


A natural, flowing body of water emptying into an ocean, lake or other body of water and usually fed along it's course by converging tributaries.

Topo50 description

Only those rivers significant by their size and location are held in the data and shown on the printed maps. River_cl is used when the river is too small to be captured at 1:50,000 as an area feature. In the instance of highly braided rivers, only a subset of the braids will be shown. Note that the NZ Geographic Board is working on a project to define the spatial extents for the river names held in the Gazetteer. When this work is complete, the name field will be populated based on these extents.

Topo250 description

Only those significant by their size or location are held in the Topo250 data and shown on the Topo250 printed maps; these are a generalised subset of those shown on the Topo50 series
