Grid to Geographic - Redfearn's Formulae

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


Interactive Maps

Interactive Maps is a discovery and exploration view of Geoscience Australia's geospatial services. The following scientific and decision support themes have curated content comprised of maps and functions. Each map has queries and functions with linked access to OGC (Open Geospatial Consortium) web services and metadata. This system replaces MapConnect and AMSIS applications.


International Quiet Days and Disturbed Days

International Quiet Days (IQD's) are the days where the geomagnetic variations are a minimum in each month. International Disturbed Days (IDD's) are 5 days in each month where the geomagnetic variations are maximum. The classification of days is relative only to the month of calculation. The average disturbance level in one month may differ from another.


K Indices from Australia

The k index is a quasilogarithmic index of geomagnetic activity relative to an assumed quiet day curve for the recording site. k is a code from 0-9 that characterizes magnetic activity (0 being the least active field and 9 the most active field) over a 3 hour period.


Landslide Search

Landslide Search allows users to search for - naturally-occurring landslides - landslides with a significant human contribution or directly triggered by humans,- flood events causing significant erosion, and - flash flood events involving mud or debris - which have been recorded by Geoscience Australia and contributing scientific organisations and returns these landslide and flood events along with their associated data. - Human-triggered landslides include events such as sand collapses caused by children digging holes or tunnels, boulders displaced by climbers, rock ledges breaking off when a person stands or sits on them, and collapses caused by excavation. Landslides are often called landslips and the terms are interchangeable.


MARine Sediments Database

The MARine Sediment (MARS) database contains detailed information on seabed sediment characteristics for samples collected from Australia's marine jurisdiction, including the Australian Antarctic Territory. It is an important scientific resource that includes survey and sample information such as locations, water depths and sample descriptions. Data are also provided from quantitative analyses of the sediments, such as grain size, mud, sand, gravel and carbonate concentrations, mineralogy, age determinations, geochemical properties, and physical attributes for down-core samples including bulk density, p-wave velocity, porosity and magnetic susceptibility. Images and graphics are presented, where available. MARS currently holds >40,000 sample and sub-sample records, and approximately 200,000 records describing the characteristics of these samples. New data are being added as they become available. Please contact us at marine.sediments@ga.gov.au if you wish to contribute marine sediment data to the MARS database.


Moonrise and Moonset Times

Compute Moonrise and Moonset Times. To use this facility you need to know the latitude and longitude of the location you want to calculate rise and set times for.


National Geospatial Reference System

The GNSS database contains metadata and data quality statistics for continuous operating GNSS stations in Australia, its Territories and the South Pacific.


NationalMap

The National Map provides easy access to authoritative and other spatial or spatially-enabled data to government, business and the public; facilitates the opening of data by federal, state and local government bodies; and provides an open framework of geospatial data services that supports commercial and community innovation.


Neotectonic Features Database

The Neotectonic Featues database contains information on faults, folds and other features within Australia that are believed to relate to large earthquakes during the Neotectonic Era (i.e. the past 5-10 million years). The neotectonic feature mapping tool allows you to: * search and explore Australian neotectonic features * create a report for a feature of interest * download feature data and geometries as a csv file or kml file * advise Geoscience Australia if you have any feedback, or wish to propose a new feature.
