A subset of Critchlow NationalMap consisting of a combination of Water layers extracted from the LINZ web portal.
The combined Water layer consists of the following water body polygons :
- River: natural, flowing body of water emptying into an ocean, lake or other body of water and usually fed along its course by converging tributaries. - Lake: any standing body of fresh inland water. - Pond: area of shallow water with walls or banks created for a specific purpose. - Reservoir: receptacle in which a large quantity of water is stored - Canal: artificial open waterway used for transportation, waterpower or irrigation. - Lagoon: sheet of salt water separated from the open sea by sand, shingle banks or a road embankment.
These layers are a component of the. Topo50 map series. The Topo50 map series provides topographic mapping for the New Zealand mainland, Chatham and New Zealand's offshore islands, at 1:50,000 scale. Further information on Topo50: http://www.linz.govt.nz/topography/topo-maps/topo50
