DATA
Data and Credits
Retisynq is built on open government data, OpenStreetMap and the sprinkler makers’ published charts. This page lists each source, its licence and the credit it asks for. The planner and every report show the credits for the data they use.
1Addresses
Incorporates or developed using G-NAF © Geoscape Australia licensed by the Commonwealth of Australia under the Open Geo-coded National Address File (G-NAF) End User Licence Agreement.
The address search and the address points behind approximate lots are built from G-NAF and come under the same licence. That licence does not allow G-NAF data to be used to compile addresses for sending mail unless each address is checked against another source first.

Western Australia, South Australia and the Northern Territory publish no open lot boundaries, so lots there are worked out (section 4) and marked as approximate.
3Street map and buildings
Map data © OpenStreetMap contributors, available under the Open Database License (ODbL), served as map tiles by OpenFreeMap © OpenMapTiles.
Where OpenStreetMap has no building, outlines come from Microsoft’s Global ML Building Footprints, licensed under the Community Data License Agreement, Permissive 2.0.
4How approximate lots are worked out
In Western Australia, South Australia and the Northern Territory, the planner works a lot out from open data. The outline is a starting point to drag to your fences, not a surveyed boundary.
- The lot starts as every spot nearer your address point than any other G-NAF address point around it, so boundaries run halfway between neighbours.
- It is cut back at each nearby road, where the road reserve begins, using OpenStreetMap’s street lines.
- It is trimmed across and along the street until its centre sits on your address point, since G-NAF places that point at the middle of the lot.
- Where a building outline’s middle falls inside it, the lot is drawn to hold that house whole.
Because these outlines are made partly from OpenStreetMap data, they are available under the Open Database License: you may reuse an approximate lot outline under that licence, crediting OpenStreetMap contributors and G-NAF as above. Your own outline is in your design, and in the copy of your data the account page gives you.
5Climate, soil and watering rules
- Climate: SILO, Queensland Government, CC BY 4.0.
- Soil: Soil and Landscape Grid of Australia (CSIRO, TERN), CC BY 4.0.
- Watering days and hours: each water authority’s and state government’s published rules, named in the watering program with the date they were read.
6Sprinkler and product data
Sprinkler, nozzle, valve, controller and drip figures come from Hunter, Rain Bird, Toro and Holman’s published charts and data sheets, and pipe and backflow figures from their makers’ published data, each record naming its source and the date it was checked. Hunter, Rain Bird, Toro and Holman are trademarks of their owners. Retisynq is not affiliated with or endorsed by them.
7Type and marks
- Apfel Grotezk, Mazius Display and Necto Mono, from Collletttivo, and Google Sans, from Google: each under the SIL Open Font License.
- The Google and Microsoft sign-in buttons follow each company’s branding guidelines. Google and Microsoft are trademarks of their owners.
