Description

A relatively permanent walled and roofed construction.

Topo50 description

Building_poly is used to capture a building where it is large enough to be captured at 1:50,000 as an area feature (generally those larger than 25m square or other shape of equivalent area) . The CBD area of large towns and cities is held in the data as a large building_poly/s. It is shown on the printed maps as a black fill with the road features above.

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

Object attributes

Attribute	LSLIFF code Shapefile field Data type	Attribute description	Attribute values*
name	1001 name string	The name of the building, 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.	"Flock House" {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
building_use	1014 bldg_use string	For substation example see powerline_cl page. For sewage plant see pond_poly page. Note: Other legitimate building use attributes will be added periodically.	See below
building_status	1013 status string	Values derelict In a state of disrepair, no longer safe to use.	derelict historic {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.
