The Australian Geoscience Data Cube — Foundations and lessons learned
2017
Abstract The Australian Geoscience
Data Cube(AGDC) aims to realise the full potential of
Earth observationdata holdings by addressing the Big Data challenges of volume, velocity, and variety that otherwise limit the usefulness of
Earth observationdata. There have been several iterations and AGDC version 2 is a major advance on previous work. The foundations and core components of the AGDC are: (1)
data preparation, including geometric and radiometric corrections to
Earth observationdata to produce standardised surface reflectance measurements that support time-series analysis, and collection management systems which track the provenance of each
Data Cubeproduct and formalise re-processing decisions; (2) the software environment used to manage and interact with the data; and (3) the supporting high performance computing environment provided by the Australian National Computational Infrastructure (NCI). A growing number of examples demonstrate that our
data cubeapproach allows analysts to extract rich new information from
Earth observationtime series, including through new methods that draw on the full spatial and temporal coverage of the
Earth observationarchives. To enable easy-uptake of the AGDC, and to facilitate future cooperative development, our code is developed under an open-source, Apache License, Version 2.0. This open-source approach is enabling other organisations, including the Committee on
Earth ObservingSatellites (CEOS), to explore the use of similar
data cubesin developing countries.
