Northern Australian Estuary Habitats from Landsat Satellite Imagery, 1990s-2020s

A three-decade Landsat time series from the Digital Earth Australia archive was used to map intertidal areas and mangrove extent in seven northern Australian estuaries. The report, part of the NESP A12 Northern Seascapes Scoping Project, demonstrates methods for cloud-free composite imagery and tide-tagging to analyze habitat change. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Mapping mangrove expansion or die-back based on the multi-decade Landsat time series mentioned in the description
• Analyzing the effects of tidal dynamics on intertidal habitats using the tide-tagged satellite imagery approach
• Monitoring coastal habitat change for species management using the Intertidal Extent Model from Digital Earth Australia
• Developing habitat extent monitoring tools by integrating new satellite data streams like Sentinel-2

Strengths

• Analysis covers a three-decade long Landsat time series.
• Focuses on seven specific estuaries in northern Australia: Darwin Harbour, Keep, Daly, Roper, Macarthur, Flinders, and Gilbert River.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data format is PDF, which may limit direct machine-readability of underlying geospatial data.
