NZ Topo - object class beacon_pnt
This page describe the beacon_pnt object class used to represent objects in the NZTopo topographic database.
A fixed signal, mark or light erected for the guidance of mariners or aeroplane pilots.
Only those significant either by their size or location are held in the data and shown on the printed maps. Where a beacon is located close to a trig, the beacon point symbol is replaced on the printed map by the text 'Beacon'. If two or more beacons are in close proximity, a single beacon feature may be held in the data and shown on the printed map.
Only lighthouses are held in the Topo250 data and shown on Topo250 maps : that is where beacon_type = lighthouse

|Attribute description||Attribute values*|
|The name of the beacon, 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/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|
|derelict: In a state of disrepair, no longer safe to use.|
|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.|
