Object attributes

Attribute	LSLIFF code Shapefile field Data type	Attribute description	Attribute values*
name	1001 name string	Name of the lake, 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.	"Lake Pounui" {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
elevation	1021 elevation real	The elevation of the water body above mean sea level.	{empty}
lake_group_name	1044 grp_name string	The name of the group of lakes that this individual lake belongs, where known. Text data from July 2012 will be in UTF-8 format.

group_name_macronated	1141 grp_macron boolean	Indicates whether the entry in the group_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
lake_use	1045 lake_use string		hydro-electric evaporation reservoir {empty}
lake_temperature	1046 temperatur string		hot {empty}
lake_perenniality	1047 perennial string	Values dry The lake does not contain water most of the time seasonal The lake contains water seasonally through the year {empty} The lake contains water throughout the year	dry seasonal {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.
lake_group_name_ascii	9002 grp_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 field, 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.
