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

Digital Earth Australia (DEA) is a national analysis platform for satellite imagery and Earth observation data. It is developed by Geoscience Australia, CSIRO, and the National Computational Infrastructure (NCI) to track environmental changes across Australia. The platform processes data to identify soil erosion, coastal changes, crop growth, and water quality.

Use Cases

• Monitor soil and coastal erosion based on satellite imagery analysis.
• Track crop growth and agricultural potential using time-series Earth observation data.
• Assess water quality changes in Australian regions from processed satellite data.
• Analyze urban and regional development changes identified from satellite imagery.

Strengths

• Built on the award-winning Australian Geoscience Data Cube, recognized as the 2016 Content Platform of the Year.
• Developed through a partnership between Geoscience Australia, CSIRO, and the NCRIS-supported National Computational Infrastructure (NCI).
• Designed to track changes across Australia in unprecedented detail, as stated in the description.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• The primary file format listed is PDF, which may not contain the raw, machine-readable data.
