LINZ geo name matching

This page is a bit of a sandbox where we will hash out how we will match geographic name data for the LINZ data import's geographic_name layer (previously named geo_name in the V16 version of the dataset). The full list is stored in the LINZ-2-OSM web app with JavaScript logic. When complete we will publish the data_dtd.xml file here.

• See the LINZ OSM wiki page for more info about the import.

• See the LINZ data sets page for a list of LINZ datasets. The LINZ online data dictionary which explains each layer in detail can be found here.

The LINZ webpage for the geographic names layer is here.

• See the LINZ attribute matching wiki page for more traditional geo-feature tag matching.

geographic_name

• LINZ data dictionary for the geographic_name layer

• These are all named point features. ()

• Many of these will fall under Key:place or place=locality

Tag application script

# script to search for tags and insert new OSM tags based on a '|' separated table file.
#  specifically written for the LINZ geo_name data import but fine for general use

# table example:
#AIR|aeroway=aerodrome
