The slow advance of sand around Double Island Point (south-east Queensland), near the end of its multi-million-year journey northwards before disappearing into the abyss at the tip of K'gari / Fraser Island...

Pretty fantastic! Nice to see the @sentinel_hub cloudless model being applied here too, a sensible choice!

Yesterday morning, the powers of @NASA_Landsat and @CopernicusEU #Sentinel2 combined to produce this incredible snapshot of flooding across Australia's Gulf of Carpentaria.🛰️📸

This false colour animation covers a distance of over 1000 km!

Couldn't be more excited about this major #DigitalEarthAU update: a brand new #Sentinel2 satellite data collection for Australia!

Too many improvements to fit in a single tweet - see the 🧵 below for some of the biggest highlights! https://twitter.com/GeoscienceAus/status/1620632976735494147

An incredible satellite view of the Murray River flood plume - thick turbid water pushing up against milky coastal and darker ocean waters offshore of the Murray Mouth in South Australia's Coorong region.

Some amazing flow dynamics along the lower river channel river as well!

Finishing the year with some beautiful satellite imagery: three decades of spectacular subtidal dynamics at the southern tip of Moreton Island in south-east Queensland, driven by the slow drift of sand northward along Australia's east coast.

@Axman6 @bmedlyn Yep! We have our own #DigitalEarthAU Terria map that serves as a simpler version of National Map containing just our DEA satellite datasets and products 🙂

A mind-blowing transformation from drought to flood across the Ramsar listed Macquarie Marshes and Macquarie-Barwon floodplain in south-eastern Australia over the past three years:
