SLIPStream is changing

We’re excited to announce that from early 2019, the DataWA blog will be the new home for SLIPStream content. Our business has evolved, and the focus of SLIPStream has shifted away from updates about the SLIP Future project to be more data focused.

Articles will be posted on a regular basis and will include most of the news you are used to, plus a new feature, ‘Data stories’.

Data stories will be a series of short articles that share:

  • how data enabled something new to happen
  • the integration of data in other agencies
  • details of collaboration and technical achievements
  • how data helps to solve major social issues.

Keep an eye out on DataWA for new posts starting in 2019. Don’t worry, you will still receive an email to let you know when new content is added.

Notice | SLIP subscription data changes

Landgate will make some minor improvements and additions to its Tenure and Reserves services which will benefit many of our SLIP data customers. We understand that changes can have an impact on your systems, so please take the time to review these to prepare and make the necessary changes.

The Business Sales and Service Team are always here to help. Please contact them on +61 (0) 9273 7683 or if you have questions about the changes.

On Wednesday 28 November 2018, Landgate will add two new layers to the Crown Reserves subscription service:

On Wednesday 12 December 2018, Landgate will change existing layers in the following subscription data:

  • Land Tenure (LGATE-226)
    A minor change is required to amend the data length of the LOT_PREFIX attribute from 1 to 2 characters.
    This amendment can be applied to data sources in advance of the change to receive the new data once applied.
  • Reserves (LGATE-227)
    The addition of eight (8) new attributes relating to Management Orders to enable the ability for users to search management orders based on organisation _ code. This removes the need to know all variations of organisation/ agency names.

Please subscribe to receive notifications via the SLIP status page for more information and the dates on which these changes will occur.

If you have questions or would like to provide feedback on the dates of the changes, please contact Business Sales and Service Team on +61 (0) 9273 7683 or

What do you know about the Capture WA program?

The Capture WA program coordinates aerial imagery capture across WA. It is designed to maximise sharing of location data assets by planning, recording and acquiring the information through one channel, ensuring the best use of resources.

The program is available to all state and local government agencies. It saves money by:

  • combining buying power to secure the best value services
  • avoiding duplication of effort and costs by sharing the data and information collected – ensuring Intellectual Property remains with the state
  • providing a flexible range of options for procurement, including access to the latest technology for data capture.

Read about the available data categories and common data capture requests.

How do I request data capture?

The 2019 capture program will be opening soon. An annual planning cycle is conducted at the start of each calendar year to determine the capture priorities and allow for inclusion in budgets.

Agencies should submit their requests in the Capture WA register. Requests are assessed against available funds in consultation with other agencies. The capture plan is finalised by the end of April each year.

There are several ways to request data through the program:

  • Requests for self-funded data acquisition can be submitted at any time using the online Capture WA register. No tender process is necessary as the program offers a range of pre-qualified suppliers through the Capture WA contract and capture requests can be tailored to meet agency needs.
  • The Capture WA register now includes the option to request an informal quote. We can assist if you would like to proceed with data acquisition. The requirements, formal quote and procurement process is managed as part of the Capture WA program.
  • Notification of independent capture can be submitted at any time. If agencies prefer to self-fund capture and not use the Capture WA contract, we ask that you please inform us of this independent data acquisition by notification in the Capture WA register. This gives us insight into government data acquisition plans in addition to the usual notification and requests for capture. Pooling self-funded and co-funded requests allows for more capture, sharing and reduced duplication among government organisations.

For more information on the program, visit and download the brochure or contact the Capture WA team on (08) 9273 7093.

SLIP access | Modernising TLS

What is TLS?

TLS stands for Transport Layer Security. It’s a protocol that encrypts and authenticates secure connections across the web. It provides privacy and data integrity for web browsers and other applications that require data to be securely exchanged over a network.

The versions of TLS are TLS 1.0, 1.1, 1.2, and 1.3.

What’s happening to TLS 1.0 and 1.1?

TLS 1.0 will be 20 years old in January 2019.

TLS 1.2 was published 10 years ago to address weaknesses in TLS 1.0 and 1.1. It’s been the recommended version for protocols since 2008 and has been widely adopted. Newer versions of TLS are more advanced, better performing and provide a more secure connection. TLS 1.2 is broadly supported across modern browsers and this means a safer browsing experience for everyone.

It is expected that the Internet Engineering Task Force (IETF) will formally deprecate TLS 1.0 and 1.1. When that happens, protocol vulnerabilities in these versions will no longer be addressed by the IETF.

What does this mean for me?

Landgate will be removing support for TLS 1.0. Applications and web browsers using TLS 1.0 will not be able to connect to SLIP data services and Maps when support is removed.

This change is in line with the announcement that Apple, Google, Microsoft, and Mozilla plan to disable TLS 1.0 and 1.1 support in their browsers in the first half of 2020.

Please note that this change is not happening soon, but this is a heads up that you need to begin to move off TLS 1.0 (and TLS 1.1 in the future) and make sure your applications and browsers can support TLS 1.2.

If you are using a recent version of Chrome or Firefox, or Internet Explorer 11 to access SLIP, then you are most likely already connecting with TLS 1.2 and will not be affected by this change.

If you have queries or issues, please contact Business Sales and Service Team on +61 (0) 9273 7683 or

Esri ArcGIS users

The ArcGIS platform web and API connections use TLS as a key component of their security. HTTPS (web) uses TLS as a key component of its security.

ArcGIS Online will be upgrading to TLS 1.2 in February 2019. When this occurs, ArcGIS Online services will only accept connections using TLS 1.2 and is likely to affect most ArcGIS software and custom solutions.
