Digital Earth Australia (DEA) is a an initiative by Geoscience Australia, an agency of the Australian Government. It creates free and open satellite data products for Australia.

DEA services include many of their pre-processed, higher level products, such as:

  • Surface reflectance
  • Fractional vegetation and ground cover¬†
  • Coastlines
  • Water observations

In addition to creating and curating data products, they maintain several tools, which are listed below.

DEA’s Open Data Cube (ODC) Sandbox

DEA’s ODC Sandbox is a cloud-based sandbox with a custom Python environment. It provides access to Python tools and in-house data through Geoscience Australia’s Open Data Cube Python library.

Digital Earth Australia

Digital Earth Australia (DEA) is a platform that uses spatial data and images recorded by satellites orbiting our planet to detect physical changes across Australia in unprecedented detail. For instance, it identifies soil and coastal erosion, crop growth, water quality, and changes to cities and regions.

 

Using high performance computing power provided by the National Computational Infrastructure and commercial cloud computing platforms, DEA organises and prepares satellite data into stacks of consistent, time-stamped observations that can be quickly manipulated and analysed to provide information about a range of environmental factors such as water availability, crop health and ground cover.
