Database to provide descriptions and images of the Australian Fundamental Gravity Network (AFGN) stations to Gravity Surveyors and the general public. The Australian National Gravity Database (ANGD) is underpinned by the AFGN, which provides the datum for gravity surveys conducted throughout Australia. The AFGN is a network of permanently marked and documented gravity base stations which allow gravity surveys to tie their surveys to a consistent datum. Geoscience Australia maintains the Network with assistance in the form of updates from State and Territory Geological Surveys, Surveyors, and the general public. Geoscience Australia maintains the ANGD, which contains data from gravity surveys conducted throughout Australia and its Remote Offshore Territories. These data have been sourced from within Geoscience Australia, State and Territory governments and agencies, mineral and petroleum exploration companies, universities and overseas organisations.

Geodetic Calculations - Redfearn's Formulae, Geographic to Grid Given Latitude and Longitude, calculate Easting, Northing, Zone for a Universal Transverse Mercator (UTM) projection, Grid convergence and Point Scale Factor.

ALOS Group Purchase is a new facility provided by ACRES for various approved customers/agencies to access the same ALOS data over a common area using ACRES online ordering.

Geodetic Calculations - Vincenty's Formulae, Inverse Method Given latitude and longitude of two points, calculate the ellipsoidal distance and forward and reverse azimuths between the points.

This application allows the user to see a `real-time' representation of the Earth from a satellite that is currently orbiting our planet. The satellite database that provides the positioning information is updated regularly, but may not reflect the current position of satellites that manoeuvre frequently after reaching orbit.

Geoscience Australia's Geochron Delivery system is the retrieval system for geochronological data stored by Geoscience Australia. The system will be continually updated as the volume, variety and quality of available geochronological data increase. The initial (September 2011) release contains only ion microprobe (SHRIMP) data, comprising data from about 560 samples, chiefly derived from Geoscience Australia's previous Geochronology OZCHRON. Migration of further OZCHRON data, and upload of more recent data (including analyses obtained in collaboration with the States and the Northern Territory under the National Geoscience Agreement) is ongoing and continuous.

ANUGA is a software implementation of a hydrodynamic model which is specifically designed to model wetting and drying processes. ANUGA is a joint development project between Geoscience Australia (GA) and the Australian National University (ANU).

The sample online image processing system allows you to create simple RGB images covering the Murwillumbah area on the east coast of Australia. It uses Landsat Thematic Mapper (TM) satellite data, and you can select different band combinations.

This page provides quick-look images and basic metadata for all Moderate Resolution Imaging Spectroradiometer (MODIS) acquisitions made by Geoscience Australia Earth Observation in the past seven days. Each swath is labelled by orbit number and date, and is divided into scenes or "Granules". Time of day is shown using Co-ordinated Universal Time (UTC) which is similar to Greenwich Mean Time. Australian Eastern Standard time is UTC plus 10 hours. Data for download is in a specialised format suitable for image analysis by professional users. If a simple image file (*.jpg) only is required, click on the magnifying glass, then right-click on the enlarged image and Save Picture As to save to your local drive. First enlargement is approx five kilometre pixels and the second enlargement is approx one kilometre pixels. Quick-look images derived from HDF datasets are cropped at 180°E - (The HDF datasets themselves are complete).
