NZ Topo - object class building_pnt
This page describe the building_pnt object class used to represent objects in the NZTopo topographic database.
A relatively permanent walled and roofed construction.
Only those significant either by their size or location are held in the data and shown on the printed maps. Of these building_pnt is used when the area is too small to be captured at 1:50,000 as a polygon feature Where a building is located close to a road, the point held in the data and shown on the printed maps may be offset from the road a distance of up to 30m. There are more buildings held in the data than shown on the printed map; text on the printed map will mask out the building symbol. Note also that a single building feature may represent one, two or a group of buildings in close proximity.
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 the building_pnt and building_poly features shown on the Topo50 series.
Important information: The Department of Conservation or other authorities should be contacted for the latest information on tracks and huts

|Attribute description||Attribute values*|
|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.|
|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|
|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|
|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.|
