NZ Topo - object class descriptive_text
This page describe the descriptive_text object class used to represent objects in the NZTopo topographic database.
Descriptive text; object used to hold text.
Descriptive text is used to aid map and data users by displaying and holding useful information in descriptive form.
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

|Attribute description||Attribute values*|
|Description of an object not represented by a unique symbol or held as a specific feature|
|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/placenames/find-names/macrons/index.aspx for a list of places or feature names within New Zealand that are gazetted and include macrons|
|Value governing text size on LINZ printed map.|
|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.|
|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.|
