Digital Earth Australia (DEA): Satellite-Based Environmental Change Tracking

Digital Earth Australia (DEA) is a national analysis platform for satellite and Earth observation data. It is built on the award-winning Australian Geoscience Data Cube, developed by Geoscience Australia, CSIRO, and the National Computational Infrastructure. The platform processes data to track environmental changes across Australia, including soil erosion, crop growth, and water quality.

Use Cases

• Monitor soil and coastal erosion over time based on satellite imagery analysis.
• Track crop growth and agricultural productivity across Australian regions.
• Assess water quality changes in inland and coastal water bodies.
• Analyze urban expansion and changes to cities and regional areas.

Strengths

• Built on the Australian Geoscience Data Cube, winner of the 2016 Geospatial World Leadership Award for Content Platform of the Year.
• Developed as a partnership between Geoscience Australia, CSIRO, and the NCRIS-supported National Computational Infrastructure.
• Designed to track changes across Australia in unprecedented detail, as stated in the description.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific data formats beyond the listed PDF are unknown, which may limit suitability assessment.
