NZ Topo - object class gate_pnt

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


A structure that may be swung, drawn or lowered to block an entrance or passageway

Topo50 description

A selection of gates on named (ie main), connecting roads are held in the data and shown on printed maps. They are not placed on tracks. Note that in our experience 99% of the time where a named road ends and a vehicle track continues there will likely be a gate.

Data type
Attribute description Attribute values*
gate_restrictions 1030
name 1001
The name of the feature, 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.
name_macronated 1140
Indicates whether the entry in the name_ascii field contains a macronated vowel. Where the value is "Y" go to for a list of places or feature names within New Zealand that are gazetted and include macrons
name_ascii 9000
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
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.
orientation 1115
The orientation or angle of the feature as it is shown on the map. This is measured in radians starting from due east, in a counter- clockwise direction for positive numbers or clockwise for negative numbers.
