Open Source Earth Observation at Scale

The Open Data Cube (ODC) is a free, open-source software platform that simplifies the management and analysis of large amounts of satellite imagery and other Earth observation data. It allows users to easily access, process, and analyze decades of geographical data to track changes on Earth's surface over time. ODC is designed to help scientists, researchers, and government agencies make better-informed decisions about environmental issues, land use, and resource management.


Use Case Examples

Land Cover Mapping in Australia: Researchers used the Open Data Cube through Digital Earth Australia (DEA) to generate annual national-scale land cover maps of Australia, leveraging Landsat imagery from 1988-2020. This work implemented the FAO Land Cover Classification System (LCCS) Level 3 to produce six main land cover classes at 25m resolution, supporting environmental monitoring and policy-making.
