Derived data product DEA High and Low Tide Imagery
Picturing the ups and downs
Digital Earth Australia (DEA) High and Low Tide Imagery provides cloud-free imagery mosaics of Australia’s coast, estuaries and reefs at low and high tide, calculating the geometric median of the highest and lowest 20% of tides seen by Landsat satellites over decades
See Australia's coasts, estuaries and reefs at low and high tide, without the visual noise of clouds, breaking water and sun-glint
We’ve paired our archive of Landsat satellite imagery with regional tidal models, allowing imagery to be sorted by tide height as well as date
