Digital Earth Australia (DEA) Fractional Cover splits landscape observation data into three parts — or fractions — enabling measurement of green (leaves, grass, and growing crops), brown (branches, dry grass or hay, and dead leaf litter), and bare ground (soil or rock) in any area of Australia at any time since 1987.

The product can characterise any 30 square metres of Australia, giving insights into not only vegetation, soil and water, but also land, crop and grazing management. Reveal which parts of a property show heavy or under-grazing. Make adjustments and track the success of interventions

Why look at land in cover types?

  • Contribute to soil erosion, ecosystem, and vegetation modelling
  • Feed data into crop rotation, stubble management, and rangeland management
  • Provide insights into the interplay and changes in areas of vegetation and bare soil
  • Enable policy agencies, land managers and scientists to monitor land conditions over large areas and long timeframes
