HLTC

High and Low Tide Composites, a Digital Earth Australia product providing cloud-free imagery mosaics of Australia’s coast, estuaries and reefs at low and high tide.

ITEM

Intertidal Extents Model, a Digital Earth Australia product that maps the relative extent of the Australian intertidal zone at regular intervals of the observed tidal range.

NBAR

Nadir-corrected BRDF Adjusted Reflectance, where BRDF stands for Bidirectional reflectance distribution function.

NBAR-T

Nadir-corrected BRDF Adjusted Reflectance with terrain illumination reflectance correction.

NCI

The Australian National Computational Infrastructure is Australia’s national research computing facility. It provides computing facilities for use by Australian researchers, industry and government. For more information see http://www.nci.org.au/.

NIDEM

National Intertidal Digital Elevation Model, a Digital Earth Australia product derived from ITEM that maps the elevation relative to Mean Sea Level of the Australian intertidal zone.

ODC

Open Data Cube, an international open-source project developing the technology that powers Digital Earth Australia. For more information see http://opendatacube.org/ .

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 http://www.python.org/ for more.

USGS

VDI

Virtual Desktop Infrastructure is a virtual laboratory at NCI that provides a linux desktop environment for scientific computing. For more see http://vdi.nci.org.au/help.

WOfS

Water Observations from Space, a Digital Earth Australia product that provides images and data showing where water has been seen in Australia from 1987 to the present.

YAML

YAML is 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/.
