Overview

Digital Earth Australia is a platform designed to …

  • Catalogue large amounts of Earth Observation data.

  • Provide a Python-based API for high performance querying and data access.

  • Give scientists and other users easy ability to perform Exploratory Data Analysis.

  • Allow continent-scale processing of the stored data.

  • Track the provenance of all the contained data to allow for quality control and updates.

For more information, see the DEA website.

Background

DEA builds upon the globally recognised innovation: the Australian Geoscience Data Cube which was the winner of the 2016 Content Platform of the Year at the Geospatial World Leadership Awards and was developed as a partnership between Geoscience Australia (GA), the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the National Computational Infrastructure (NCI).

Technology

DEA is powered by Open Data Cube (ODC), an open-source library for the management, analysis, and processing of Geographic Information System (GIS) data — namely Earth Observation satellite data. It is a global initiative to increase the value and use of satellite data by providing users with access to free data management technologies and analysis platforms. At its core, ODC is a set of Python libraries and a PostgreSQL database that facilitate working with geospatial raster data.

The ODC source code can be found in the datacube-core repository on GitHub.
