Update from NSW Spatial Services

April 14, 2021

NSW Elevation Data Service delivers two new datasets

Two new datasets; slope and aspect, are now available through the Spatial Collaboration Portal (SCP)’s newest map viewer, the NSW Elevation Data Service.

Derived from the NSW state-wide five-metre Digital Elevation Model (DEMs) these datasets will provide authoritative terrain data to support the development of industry standards in a variety of government, agriculture, research and industrial areas. Covering the western NSW region the five-metre slope is produced from a combination of one metre and two metre resolution LiDAR DEMS and five metre resolution photogrammetric DEMs. The export function and web feature service within the SCP allow users to explore a variety of representations including slope, aspect and contours based on ground surface. For further information please visit the user guide for this new service. Availability and scales of data vary by location. 

Making slope and aspect data available through the Spatial Collaboration for download on demand is another exciting venture for Spatial Services.  As a by-product of the five-metre state-wide Digital Elevation Model from the Surface Model Enhancement Project, two metre state-wide contours are now available via the NSW Elevation Data Service. This is a huge achievement for Spatial Services and New South Wales will benefit from the availability of this seamless contour dataset available for users to download on demand as open data or to use as a webservice.

For additional information please access our How to guides to learn how to navigate the many functions that the Spatial Collaboration Portal has to offer.

Historical Imagery Viewer

Development of the Spatial Collaboration Portal (SCP) has enabled us to offer new and improved pathways to access a wide range of our data.

The portal provides a secure platform that delivers the NSW Foundation Spatial Data Framework collection to our customers on demand. Previously, access to our historical imagery was a manual process where users had to submit a request. We have streamlined this to a more user-friendly self-service supply which enables rapid delivery, reducing costs and time.

The self-service model enables users to search and discover our datasets in a secure and stable environment. A feature of the SCP, the Historical Imagery Viewer, now enables users to view and download 600 dpi images on demand, free of charge. Currently there are more than 600,000 frames which will increase upwards to over 1 million frames.

Users can also view the HAPE (Historical
Aerial Photo Enhancement) Project Mosaics over the Sydney SIX area from 1943 – 2005. Higher resolution, 2000 dpi images still need to be requested via the Service Delivery team at

This is an exciting new delivery platform of Spatial Services’ data which will progressively improve as we move through development and testing stages.

Real-time addressing validation slashes red tape in COVID-19 border closures

Spatial Services provides real-time address validation to NSW Government agencies through our NSW Point address services that are invaluable to live applications like the NSW/Vic border permits which were necessary during the COVID-19 border closures.

NSW Point address services put the customer first by providing predictive search functionality which enabled customers to quickly and accurately fill out their permit application addresses. This real-time functionality is underpinned by up-to-date datasets, direct API integration and account management support services.

In 2020 during the COVID-19 pandemic, Service NSW implemented NSW Point for real-time validation within NSW Border Permit Applications for entry from Victoria. In the NSW and Victorian Border Permit application form, NSW Point provided real-time validation of addresses entered by customers. The application determined if the user was able to submit a request for exemption to cross the NSW/Vic border, based on the user’s input address  which was verified during the application submission. During this period our services transacted over 23 million API calls for the entry applications and 5.7 million API calls to check the border zone eligibility. 

NSW Point was also used within the Border Permit’s Address Checker application. The Address Checker application used certain outputs of NSW Point to match the address to the relevant suburb. This then provided information if the applicant could proceed with an application or if the address did not fall within the Border Zone Area.

Meanwhile, Spatial Services’ Service Point application provided a visual dashboard of all border applications submitted to Service NSW. The deidentified information from each application was submitted in real-time to update the dashboard for the government’s decision makers to use analytical data.

New video explains process to identify Offensive Place Names

A place name is the most common way to identify your location or where you live, and how we apply names is important for many reasons including emergency services, economic development, preserving history and creating community.

Place names need to reflect community sensitivities, which can change over time. The subjective nature of the term “offensive” requires place names to be reviewed on an individual basis.

Spatial Services and the Geographical Names Board (GNB) have a statutory responsibility to establish, update, preserve and publicise place naming in New South Wales. The GNB strongly encourages members of the public who find a place name offensive, to start the discussion with their community.

GDA2020 – update


This update covers two key capabilities for NSW, the implementation of GDA2020 and the continuing development and expansion of the Spatial Collaboration Portal. GDA2020for NSW represents a significant advance, keeping our State-wide positioning framework current, reliable and accurate, and supporting land and property markets and infrastructure planning and delivery. The Spatial Collaboration Portal will increasingly become the single point for discovery and access of all Spatial Services’ data, products and services, streamlining processes for our customers. To ensure we get this critical service right we’re keen to have your feedback on what is and isn’t working for you so please let us know how it’s working for you. 

The Foundation Spatial Data Framework (FSDF) is now available in both GDA2020 and GDA94 datums via our new Spatial Collaboration Portal (SCP) in line with the national ANZLIC GDA2020 adoption date

Through the SCP, users can search and discover open datasets and download on demand using the export function in both GDA2020 and GDA94 datums. The SCP provides three tiers of user access however, open data is available to view without registering an account. To access groups, secured data and saved content you must register as a portal user. To become a custodian and upload data for collaboration you must first register as a user in SCP and then contact our onboarding team at ss-data.enablement@customerservice.nsw.gov.au. For more information please visit the How to Guides located on the SCP.

This year, DCS Spatial Services web services will be upgraded to support requests for WGS84, GDA94 and GDA2020. Users should anticipate an increase in the availability of GDA2020 supported services during the year. Regular updates will be supplied through direct communications and the Spatial Data web page.

The Spatial Data web page also provides a comprehensive list of available services and access instructions. While we have focussed on delivering GDA2020 via the SCP as well as through our incremental feed service, from June 2021 additional GDA2020 products and services will roll out.

There is no immediate need to transform existing datasets and workflows to GDA2020, however, clients are strongly encouraged to transition before 30 June, 2023 when GDA94 service provision ends.  We will continue to support and supply data in both GDA2020 and GDA94 over the next two years but you should contact your GIS or software provider for guidance and support to transition during this time.

Emergency mapping system transforms from hard drives to cloud

Spatial Services, Emergency Information Coordination Unit (EICU) is in the final stages of delivering a redevelopment of our Spatial Information and Mapping Systems (SIMS). SIMS is a frontline tool for emergency service responders that has previously been delivered via portable hard drive kits biannually.

As a frontline tool for emergency responders, it was very important that we were able to develop this new product to align with current technology as well as maintain and improve on how we provided this service to users.

Our development teams have worked hard to ensure that SIMS2 aligns with current technology and meets all our customers’ needs.

SIMS2 is delivered though a cloud-based solution on the ESRI platform which provides a secure environment and enables self-service for our customers. This ensures all users across the emergency services sector will have easier access to the most current SIMS available.

Spatial Services Rapid Response flood imagery now accessible as open data

Spatial Services has responded to the recent flood emergency across NSW by capturing and processing imagery of those areas most affected by last month’s rain event.

Our team have played a critical role in supporting NSW’s emergency services and communities.  Imagery has been captured at a variety of resolutions including 12cm and 15cm over the heavily impacted areas of the Hawkesbury-Nepean and Lower Clarence.

All federal, state and local government agencies, as well as the general public can access the latest flood imagery as an API. If you wish to download the mosaics please contact Service Delivery at
SS-SDS@customerservice.nsw.gov.au for access. 

There are two rapid response products available for use in a GIS environment, including a colour-infrared (CIR) and a 3-band colour mosaic image. The CIR or NRG mosaics consist of the NIR, red and green band combination and can be referred to as False-colour Infrared imagery. This band combination is useful for studying vegetation and the depiction of water.

Please see below information on how to access these products as an API via the Spatial Collaboration Portal:
