DATA APPLICATIONS

Application | Description |
---|---|

AUSGeoid09 Application |
The national AUSGeoid09 grid file, state files and 1:250,000 map sheet files can be downloaded from Geoscience Australia's ftp server. These files can be used to compute AHD heights in real time when used in Real Time Kinematic GNSS receivers. |

Australian Geomagnetic Reference Field Values Application |
An application to calculate geomagnetic field values in Australia using the 2010 Australian Geomagnetic Reference Field model (AGRF) model. |

AUSPOS Application |
AUSPOS provides users with the facility to submit dual frequency geodetic quality GPS RINEX data observed in a 'static' mode, to our GPS processing system and receive rapid turn-around Geocentric Datum of Australia (GDA) and International Terrestrial Reference Frame (ITRF) coordinates. |

Australia-wide Total Intensity Variability Application |
Using data from the six Australian continental magnetic observatories, a contour display of the rate-of-change of magnetic total intensity, F, over the continent is shown below. This provides a broad view of how F changes across Australia. The units shown on the contours are in nanoTesla per hour. The grey squares indicate the locations of the magnetic observatories. Both real-time and historic data can be displayed in this format. All maps are generated from a period of 15 minutes of observatory data and available at 15 minute intervals. |

Australian Fiducial Network Coordinates and Mark Descriptions |
The Australian Fiducial Network (AFN) consists of eight permanent, continuously operating, Geodetic GPS receivers on the Australian mainland and Tasmania. The network was initially observed during the International GPS Service for Geodynamics (IGS) Epoch '92 campaign, July-August, 1992. The AFN, in conjunction with additional sites beyond the Australian mainland, forms the Australian Regional GPS Network (ARGN). |

Calculating Moonrise and Moonset Times Application |
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. There are several ways you can determine this: |

Calculating Sun, Moon Azimuth and Elevation |
Compute Sun and Moon Azimuth & Elevation To use this facility you need to know the latitude and longitude of the location for which you want to calculate the azimuth and vertical angle. There are several ways you can determine this: |

Geographic to Grid Application |
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. |

Grid to Geographic Application |
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. |

International Quiet Days (IQD) and International Disturbed Days (IDD)
Application |
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 Application |
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. |

Minute Values Request Form Application |

National Geospatial Reference System NGRS Application |
The GNSS database contains metadata and data quality statistics for continuous operating GNSS stations in Australia, its Territories and the South Pacific. |

OCCAM VLBI Processing Software Applications |
OCCAM VLBI Processing Software FTP site Geodetic Very Long Baseline Interferometry (VLBI) observations provided the first direct confirmation of tectonic plate motion at the end of the 1980s. Now VLBI observations measure the motions of stations with accuracy better than 1mm/year together with other space geodetic techniques such as Global Positioning System (GPS) and Satellite Laser Ranging (SLR) Analysis. |

Vincenty Direct Application |
Geodetic Calculations - Vincenty's Formulae, Direct Method Given the latitude and longitude of a point (1) and the forward geodetic azimuth (1-2) and ellipsoidal distance to a second point (2), calculate the latitude and longitude of the second point and the reverse azimuth (2-1). |

Vincenty Inverse Application |
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. |

Sunrise, sunset and twilight times application |
Computes sunrise, sunset and twilight times using the National Gazetteer of Australia. |
