NZ Topo - object class mine_poly

This page describe the mine_poly object class used to represent objects in the NZTopo topographic database.

Description

An excavation in the Earth for the purpose of extracting minerals.

Topo50 description

Only those significant either by their size or location are held in the data and shown on the printed maps. Of these, mine_poly is used when the area is large enough to be captured at 1:50,000 as an area feature. Smaller features are captured as a point

Attribute descriptionAttribute values*
name1001
name
string
The name of the mine, 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.

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/placenames/find-names/macrons/index.aspx for a list of places or feature names within New Zealand that are gazetted and include macrons

UFID1000
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.
