Through Commonwealth and State/Territory government partnerships, the National Location Information (NLI) Branch implements cutting-edge approaches to integrate and deliver data, services and analytical capability to the public, Government and critical industries. This DGAL will present examples of NLI’s work - work central to the Australian Government’s ambitious Digital Economy Strategy to make Australia a leading global digital economy by 2030, along with the Australian Data Strategy, to ensure government data is in the ‘best state’ to feed this future digital economy. Specifically, the talk will cover: The Digital Atlas of Australia Improving geospatial data and services discovery, share and access The Australian low-water coastline Bringing historic aerial imagery archive back to life ELVIS portal – creating sustainable access through collaboration

<div>GNSS, one of which is the more familiar US Global Positioning System (GPS), have become part of our everyday life… in our cars, phones and even smartwatches – helping us know where we are and where we want to go. Join me to explore advances in the analysis of GNSS in an Australia context.</div><div>Knowing our ‘place in space’ is an inherent human emotive connection and Global Navigation Satellite Systems (GNSS), as a technology, has become prevalent in the world around us, and as a society we have become reliant on basic functions such as knowing where we are, and how to navigate from one place to another.</div><div>Advances in analysis of GNSS observations has led to us being able to determine a location down to the sub-millimetre; calculate precise orbital arcs of low earth satellite platforms that are exploding in numbers for innovative communication technologies and earth observation; define how wet the troposphere is, and assist weather forecasting models; and even provide real-time precise positioning at the centimetre-level for a variety of applications.</div><div><br></div><div>This presentation will take you through advances in positioning and navigation technologies through the lens of GNSS products and services based at Geoscience Australia, and how these benefit everyday Australians.</div><div><br></div>

<div><em>Seabed geomorphology</em> describes the shape and evolution of underwater landscapes. These landscapes interact with ocean currents to create diverse marine habitats. Similar to geological maps on land, maps of seabed geomorphology are vital for making informed decisions to support the sustainable growth of our Ocean Economy.</div><div><br></div><div>As we gather more detailed seabed data and face increasing ocean pressures, there's a need for new, standardised maps that support consistent decision making at multiple scales and between administrative jurisdictions. Dr Rachel Nanson and an international team have developed a new seabed geomorphology classification system that is designed to simplify complex seabed interpretations into a map format that is accessible to a broad range of end users.</div><div><br></div><div>This approach is being adopted internationally and is currently being implemented by Geoscience Australia. We are using the method to map parts of Australia’s extensive Marine Park network and to support government to make informed decisions regarding Australia’s rapidly expanding Offshore Renewable Energy sector</div>
