NZ Topo - object class track_cl

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

Description

A deliberately formed route of a lesser quality than a road

Topo50 description

Only those significant either by their size or location are held in the data and shown on the printed maps.

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

Important information: The existence of a road or track does not necessarily indicate public right of access. Closed foot tracks are defined as being no longer maintained or passable and should not be used by recreationalists; the Department of Conservation or other authorities should be contacted for the latest information on tracks. Foot tracks in alpine areas are of a varying degree of spatial accuracy and currency; contact Department of Conservation for the latest information about alpine tracks.

Shapefile field
Data type
Attribute description Attribute values*
name 1001
name
string
Name of the track, where known. Text data from July 2012 will be in UTF-8 format. If your system is not UTF-8 compliant, you will need to use the name_ascii attribute, which has had any macronated vowels removed. UTF-8 stands for Unicode Transformation Format-8. It is an octet (8-bit) lossless encoding of Unicode characters. UTF-8 encodes each Unicode character as a variable number of 1 to 4 octets, where the number of octets depends on the integer value assigned to the Unicode character. It is an efficient encoding of Unicode documents that use mostly US-ASCII characters because it represents each character in the range U+0000 through U+007F as a single octet. UTF-8 is the default encoding for XML.
"Heaphy Track"
{empty}
name_macronated 1140
macronated
boolean
Indicates whether the entry in the name_ascii field contains a macronated vowel. Where the value is "Y" go to http://www.linz.govt.nz/regulatory/place-names/find-place-name/find-m%C4%81ori-place-names-dual-names-and-alternative-names for a list of places or feature names within New Zealand that are gazetted and include macrons
Y
N
track_use 1101
track_use
string
Values
foot Foot tracks in residential areas less than 100m long, eg those connecting two streets, are not captured or shown
cycle only Some walking tracks are being designating for mountain bike use only. Where known, these tracks have a track_use value of 'cycle only'
foot
cycle only
vehicle
track_type 1102
track_type
string
Values
route Unformed track which is natural and may be rough. May be marked by markers, poles or rock cairns. Suitable for people with a high level of backcountry skills and experience, navigation and survival skills.
connector feature used to connect sections of track where no physical evidence of a track exists. For example along a water course or through a tidal area.

track_status 1136
status
string
Values
closed defined as being no longer maintained or passable. NOTE that "closed" applies only to foot tracks
closed
{empty}
name_ascii 9000
name_ascii
string
Text data from July 2012 will be in UTF-8 format. If your system is not UTF-8 compliant, you will need to use this attribute, which has had any macronated vowels removed.
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.
