Description

An isolated rock or rock formation between high and low tides.

Topo50 description

Only those significant either by their size or location are held in the data and shown on the printed maps. Of these rock _pnt is used when the area is too small to be captured at 1:50,000 as a polygon feature

Topo250 description

Only those areas significant by their size or location are held in the Topo250 data and shown on the printed maps; these are a generalised subset of those shown on the Topo50 series.

Ant50 description

Topo50 True Only those significant either by their size or location are held in the data and shown on the printed maps. Of these rock _pnt is used when the area is too small to be captured at 1:50,000 as a polygon feature

Object attributes

Attribute	LSLIFF code Shapefile field Data type	Attribute description	Attribute values*
name	1001 name string	The name of the rock, 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.	"Thoms Rock" {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
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.
