Data collected from Geodetic GPS observation campaigns over the last 15 years. This data set is from non-continuous GPS sites. It is a combination of surveys undertaken by Geoscience Australia, State collaborators and international collaborators.

This collection includes Global Navigation Satellite System (GNSS) observations from long-term continuous or semi continuous reference stations at multiple locations across Australia and its external territories, including the Australian Antarctic Territory. <b>Value:</b> The datasets within this collection are provided on an openly accessible basis to support a myriad of scientific and societal positioning applications in Australia. These include the development and maintenance of the Australian Geospatial Reference System (AGRS); the densification of the International Terrestrial Reference Frame (ITRF); crustal deformation studies; atmospheric studies; and the delivery of precise positioning services to Australian businesses. <b>Scope: </b> Data from reference stations across Australia and its external territories, including the Australian Antarctica Territory. <b>Access: </b> To access the datasets and query station information visit the <a href="https://gnss.ga.gov.au./">Global Navigation Satellite System Data Centre</a>

The Clip and Zip tool takes an input polygon extent as WKT input and clips required featureclasses listed. The data is referenced from its own database with all layers projected to 4326 spatial reference. The output is a zipped file geodatabase with a copyright text file included.

The national measurement system in Australia ensures a basis for legally traceable, consistent and internationally recognised measurements. With the growing societal dependency on GPS, the need for the legal traceability of GPS positions with respect to the Australian Datum - the Geocentric Datum of Australia 1994 (GDA94) -- has become increasingly apparent. In the interest of ensuring consistency of positions derived from private and government Continuously Operating Reference Stations (CORS),Geoscience Australia maintains an appointment as a legal metrology authority in accordance with the National Measurement Act 1960 and provides legally traceable positions. This presentation will overview Geoscience Australia's approach to the legal traceability of GPS positions, the process of legal certification including: (1) the basic requirements for requesting certification; (2) quality standards and the quality management system of the position verification processes. The structured maintenance and continual improvement program for the verifying laboratory will also be introduced.

The AMSIS Distance To tool calculates the distance to a selected marine feature. The output is the distance to the nearest feature from the given location.

The annual Asia Pacific Regional Geodetic Project (APRGP) GPS campaign is an activity of the Geodetic Reference Frame Working Group (WG) of the Regional Committee of United Nations Global Geospatial Information Management for Asia and the Pacific (UN-GGIM-AP). This document describes the data analysis of the APRGP GPS campaign undertaken between the 16th and 22nd of September 2018. Campaign GPS data collected at 101 sites in ten countries across the Asia Pacific region were processed using version 5.2 of the Bernese GNSS Software in a regional network together with selected IGS (International GNSS Service) sites. The GPS solution was constrained to the ITRF2014 reference frame by adopting IGS14 coordinates on selected IGS reference sites and using the final IGS earth orientation parameters and satellite ephemerides products. The average of the root mean square repeatability of the station coordinates for the campaign was 1.8 mm, 1.6 mm and 5.4 mm in north, east and up components of station position respectively.

The Criteria Assessment tool takes the input path or area created by the user and the input variables chosen to generate a heat map surface, KML surface, KMZ surface and PDF Report. This service is specifically for use within the Carbon Capture and Storage application.
