psma-admin-bdys

Some utils to make it easier to use Geoscape's Administrative Boundaries

locality-clean

A Python script for creating a clean version of the Suburb-Locality boundaries for presentation or visualisation.

Trims the boundaries to the coastline; fixes state border overlaps and gaps; and thins the boundaries for faster display performance in desktop/mobile browsers and GIS tools.

This process takes ~30-45 mins.

Important

The cleaned and thinned localities have a reduced precision of 1-2m; however this is within the general precision of the property boundary data (Geoscape Cadlite) used to create the locality boundaries.

I Just Want the Data!

You can run the script to get the result or download the data from here:

Missing localities

Trimming the boundaries to the coastline removes a small number of bay or estuary based localities. These have very few G-NAF addresses.

These localities are:
