Glossary

This page lists definitions for terms used in the Open Data Cube and this manual.

AGDC
Australian Geoscience Data Cube
An Australian project that developed the python library that became ODC.
API
Application Programming Interface
The Data Cube Application Programming Interface gives programmers full access to the capabilities of the Cube, allowing query and advanced data retrieval.
CEOS-SEO
Committee on Earth Observation, Systems Engineering Office
Another group of developers working on ODC
CRS
Coordinate Reference System
Specifies how a set of coordinates relates to a point on the earth.
CSIRO
Commonwealth Scientific and Industrial Research Organisation
An Australian research agency participating in development of ODC
DEA
Digital Earth Australia
Geoscience Australia’s deployment of ODC, hosted at the NCI. See the DEA user guide for details on how to access the platform.
GA
Geoscience Australia
The primary public sector geoscience organisation in Australia. It supports ODC through the development of Digital Earth Australia. For more information see http://www.ga.gov.au/dea/.
grid spec
Grid Specification
A definition of how some raster data relates to a geospatial grid. Includes a CRS, a zero point, and an X and Y scale.
HPC
High Performance Computing
A supercomputer. These days typically a cluster of high performance computers linked together with high speed networking.
Landsat
A series of US owned earth observation satellites, with freely available data.
MODIS
US owned earth observation satellites with freely available data.
NCI
National Computation Infrastructure
Australia’s national research computing facility. It provides computing facilities for use by Australian researchers, industry and government. For more information see http://nci.org.au/.
ODC
Open Data Cube
Software for storing, managing and accessing Earth Observation data, and the community formed to further it’s development.
OGC
Open Geospatial Consortium
Open Geospatial Consortium. An organisation which makes geospatial standards, especially relating to web services.
PostgreSQL
The high performance database engine used as an index of Datasets by the Data Cube. It is both a relational and document database, and the Data Cube schema makes use of both of these capabilities.
Python
The programming language used to develop the Data Cube. It is easy to use while still allowing high performance access and processing capabilities. See https://www.python.org/ for more.
USGS
United States Geological Survey
The USA government organisation which operates both the Landsat and MODIS satellites, which are available as free an open earth observation data.
VDI
Virtual Desktop Infrastructure
A virtual desktop environment at NCI that provides a linux desktop environment for scientific computing. For more see http://vdi.nci.org.au/help.
WMS
Web Map Service
A standard for delivery published maps into web browsers and GIS software, defined by the OGC.
YAML
Yet Another Markup Language

A human friendly data serialization standard for all programming languages. It is used for all on disk metadata files and product definitions in the Data Cube.

For more information on the YAML standard see http://yaml.org/.
