Sydney Subdivision Maps Crowd-sourcing Project

Match our collection of old subdivision plans to contemporary maps and help reveal the original locations of streets and houses across Sydney's outer suburbs.

How to use the georeferencing tool

NSW Georeferencer

This video explains how to georeference NSW subdivision maps.

The State Library needs your help in geo-referencing (mapping points on two separate maps) our collection of historic subdivision plans.

It only takes a few minutes to complete a plan using our online mapping tool, and matching the maps is simple and fun! 

We suggest you view the 'how to' video above and then visit the Map Georeferencing website to get started straight away. 

Tips before getting started:

  • The subdivision plans were made for selling real estate. They are not surveyed maps and therefore do not  fit precisely onto contemporary maps. When  geo-referencing these maps you may not be able to get a perfect match.
  • We are also asking that when you clip the borders of the map you clip the entire rectangle of the poster, not just the map area so we can keep all the poster information. 
  • You will need to create an account before you start but if you are unsure of how to use the online tool we are happy to help,  just send us an email.
