Object attributes

Attribute LSLIFF code
Shapefile field
Data type
Attribute description Attribute values*
information_displayed 1182
Description of an object not represented by a unique symbol or held as a specific feature
"Aluminium Smelter"
"Container terminal"
name_macronated 1140
Indicates whether the entry in the name_ascii field contains a macronated vowel. Where the value is "Y" go to for a list of places or feature names within New Zealand that are gazetted and include macrons
linz_text_size 2006
Value governing text size on LINZ printed map.
name_ascii 9000
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
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.

* See explanation of attribute values for more information about how attribute values are represented.
