NZ Topo - object class residential_area_poly
This page describe the residential_area_poly object class used to represent objects in the NZTopo topographic database.
Description
The group of houses and their sections that together make up a residential area
Topo50 description
A group of houses and buildings which cover an area greater than 90,000m square are generally captured as a residential_area_poly rather than the individual features of building_pnt and building_poly. Features within the residential area such as trees, masts, fences, powerlines etc are not held in the data or shown on the printed maps
Topo250 description
Only those areas 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

Object attributes
| Attribute | LSLIFF code Shapefile field Data type | Attribute description | Attribute values* | ||
|---|---|---|---|---|---|
| name | 1001 name 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 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 |
| ||
| 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. |
