Final reminder | Improved Landgate data through SLIP

Landgate listened to your feedback and is making improvements to how data is delivered through SLIP. These enhancements will better align with recent changes to geospatial data and Landgate’s business systems.

This is the final reminder that if you have SLIP data integrated into your business systems, you have until 31 October 2018 to incorporate the changes.

Existing layers will still be available in parallel until 31 October 2018. However superseded layer URLs (both public and subscription) will not be available on after 17 October 2018.

The new layers are published, with the exception of some SLIP public services and the LandInfo WA subscription package:

Please refer to the Landgate data changes page on DataWA for further information. Be sure to check out the new data dictionaries and change comparison logs that detail the relevant changes.

SLIP customer survey

We need your feedback to ensure we continue to provide quality spatial data services that meet your needs.

Later this month you will receive a request from SLIP services to complete a short survey. We need your invaluable input to help test our content and make sure we are on the right track.

GDA2020 WA update

Landgate have achieved minimum compliance and are pleased to announce that geospatial data is available for delivery in GDA2020 upon request. For information on how to request data in GDA2020, please email the geospatial team at or the Business Sales and Service Team on +61 (0) 9273 7683 or email

To make all existing Landgate GDA94 data available via transformation requires changing our systems to operate and maintain data in GDA2020. This requires significant investment and we are working on the most suitable solutions. At this stage, Landgate is intending to implement GDA2020 into the Spatial Cadastral DataBase (SCDB) system next financial year.

DataWA and SLIP

WA’s open data platform, is the go-to place for discovering and accessing government data. This includes Landgate data and SLIP services which can be downloaded in a variety of formats or accessed as SLIP web services.

A project is underway to enhance the open data platform which includes better integration and automation of the data catalogue with SLIP, an architecture review and software updates that will support GDA2020. The project runs until mid-2019; details and progress will be shared with data custodians and stakeholders.

In the meantime, geodetic data can be downloaded in any of the available datums or accessed as a WGS84 SLIP service. Geodetic Survey Marks are also available as a GDA2020 shape file from

Contact the Open Data team at if you would like to discuss GDA2020 implications for data downloads or SLIP services.


If you have not seen it yet, check out this very informative video by Esri Australia to see how the new version of ArcGIS can help your organisation to enable GDA2020. We highly recommend it to understand the Null transformation dilemma facing Esri.


Metadata is extremely important! now includes a ‘Geospatial Source Projection’ field in the additional information form. This is the basic information that shows the details about the data upfront.

For data publishers, in addition to completing this form when you load data, we also suggest that you provide comprehensive metadata and a data dictionary to support good use of your data.

For more information on GDA2020 and modernising Australia’s datum, see the Geoscience Australia website, the ICSM website, or visit the official GDA2020 forum.

Morrison convenes Digital Council

Prime Minister Scott Morrison has wasted no time convening a meeting of State and Federal Digital Ministers, with the aim of knock-down obstacles to setting up better arrangements for cross-jurisdictional data sharing and an improved digital identity framework.

The newly-established Australian Digital Council brings together Ministers with responsibility for public data and digital transformation programs.

Google is making it easier to discover datasets

There are many thousands of data repositories on the web, providing access to millions of datasets; and local and national governments around the world publish their data as well.

Dataset Search lets you find datasets wherever they’re hosted, whether it’s a publisher's site, a digital library, or an author's personal web page. To create Dataset search, we developed guidelines for dataset providers to describe their data in a way that Google (and other search engines) can better understand the content of their pages.
