Description

A closed pressure system,usually constructed of steel or ferro concrete pipes.

Topo50 description

Only an incomplete selection of pipelines has been able to be collected. As a result underground gas pipelines have become a legacy feature. This means that they will remain in the data until a sheet undergoes revision. During this process, any underground gas pipelines will be deleted for that sheet.

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

UFID	1000 t50_fid integer	A unique identifier for use on Topo50 data in the LINZ Data Service. This is not a universal ID. The intention is to manage these ID’s as persistent, however this is not guaranteed and there will be instances where what appears to be a minor change to a feature may result in a new ID being assigned.
