Ensuring Access to Precise Positioning by Improving Geodetic Standards
Abstract
Within the next five years, Global Navigation Satellite Systems (GNSS), with corrections from internet or satellite communications, will permit national coverage of positioning services with real-time accuracy of several centimetres or better. This will open up a wide range of positioning applications for new industries (e.g. intelligent transport systems, precision agriculture, location based services etc.) and enable existing industries to improve productivity, efficiency, safety and understanding of the Earth to assist in making important decisions. To support new and existing users, it is essential that geodetic data is Findable, Accessible, Interoperable and Reusable (FAIR) to maximise data potential. This includes the need to move away from ASCII based standards (flat files) used by geodesists today, to machine-to-machine communication to improve the efficiency, robustness and accuracy with which data and metadata are shared. Current standards for delivering geodetic data will not adequately serve the needs of new (non-geodetic) users, who will emerge on account of the rapid growth in precise positioning services. Broad, multi-domain, standards are important for combining geodetic data with data from other domains. Internationally, several groups (e.g. Inspire, DCAT, ESIP, CODATA) are working on defining standards for geospatial and geophysical metadata and enhancing interoperability. However, there is no international strategy to ensure geodetic data can be easily discovered, accessed, shared and combined with other data to improve access and maximise data potential. Geoscience Australia are leading a joint working group to investigate and document the critical gaps in standards which restrict how FAIR precise positioning data is for the expected high use sectors, identify how these gaps can be filled and thereby lower the barriers to use.
