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.
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.
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.
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 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.
Delivering online mapping tools and information, this interactive service allows you to download Australian maps and data for free.
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 email@example.com if you wish to contribute marine sediment data to the MARS database.
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.
Digital elevation data which describes Australia's landforms and seabed is crucial for addressing issues relating to the impacts of climate change, disaster management, water security, environmental management, urban planning and infrastructure design. The National Elevation Data Framework (NEDF) vision is to ensure that decision makers, investors and the community have access to the best available elevation data to address the needs of today and the decades ahead.
The GNSS database contains metadata and data quality statistics for continuous operating GNSS stations in Australia, its Territories and the South Pacific.
