NZ Topo - object class runway_poly

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

Description

The usable surface where aircraft land and take-off.

Topo50 description

All known instances captured; note that the oustide perimeter of large airports are held as 'airport_poly'. In the case of airstrips, the availability cannot be relied upon as farmers may graze the land and/or erect temporary fences

name
string
The name of the airstrip, where known. Runwaus within airports are, currently, not named. 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.
