NZ Topo - object class geographic_name
This page describe the geographic_name object class used to represent objects in the NZTopo topographic database.
Description
Geographic name holds the proper noun of certain objects within the Topo databases. Geographic_name does not apply to roads, railway lines, or descriptive text - eg 'Brunner Mine' would be a Geographic_name but 'mine disused' is held in the descriptive_text feature
Topo50 description
The geographic name feature layer comprises names that are gazetted by the NZ Geographic Board, and also names from other sources. Most of the gazetted names are held in the data and shown on the printed maps, but ocassionally the limitations of scale preclude this. For authorativie information regarding gazetted geographic names see http://www.linz.govt.nz/placenames/index.aspx. Functions within the LINZ database allow the text to be curved, spaced and placed as it is seen on the map. Be aware that, of the 57,000 names in the database, an estimated 70% have coordinates that are coincident with the real-world feature in the topographic database that it names. Of the features where there are no real-world equivalents (such as bay, point and hill range names), most coordinates remain unaltered from the original capture in the 1980s. At that time demand and resources were such that the quickest method was chosen - to capture the feature at the left lower corner of the text as printed on the 1:50,000 topographic map. Overtime, the remaining 30% of geographic names will be repositioned.

Attribute description | Attribute values* | ||
|---|---|---|---|---|---|
| name | 1001 name string |
This field must be populated. 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. |
|
||
| 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 |

| point_description_code | 1056 desc_code string |
The named object category. | See below | ||
| linz_text_size | 2006 size real |
Value governing text size on LINZ printed map. |
|
||
| 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. |
