This project led by Geoscience Australia is using satellite remote sensing imagery to map coastal habitats critical to threatened and migratory species in northern Australia.

Change detection algorithms developed to analyse key environmental parameters in the coastal and marine zone are bing applied to the extensive time-series of earth observation image data in the Australian Geoscience Data Cube (AGDC). The resulting spatial information will quantify historical change and ongoing monitoring and provide change detection capabilities, contributing to management decisions and evaluation.

Phase 1 of this project demonstrated the use of AGDC by developing an inter-tidal zone change detection algorithm and dataset. Phase 2 involves developing and implementing an expanded range of stakeholder targeted algorithms to guide decision making.
