ggim.un.org “Positioning geospatial information to address global challenges” Global Geodetic Reference Frame  The GGRF underpins the global coordinate system  Allows us to know where we and things on the Earth are

ggim.un.org “Positioning geospatial information to address global challenges” Global Geodetic Reference Frame  The GGRF underpins most geospatial data  It’s inherent in GPS coordinates

ggim.un.org “Positioning geospatial information to address global challenges” Global Geodetic Reference Frame  All countries can and (if possible) should contribute to the GGRF

ggim.un.org “Positioning geospatial information to address global challenges” Global Geodetic Reference Frame  Today’s GGRF is an enormous improvement over geodetic infrastructure developed before satellite geodesy

ggim.un.org “Positioning geospatial information to address global challenges” Global Geodetic Reference Frame  The GGRF is a sparse global infrastructure of core observatories

ggim.un.org “Positioning geospatial information to address global challenges” Global Geodetic Reference Frame  The GGRF is needed for high accuracy satellite positioning  GNSS networks provide access to the GGRF

ggim.un.org “Positioning geospatial information to address global challenges” Global Geodetic Reference Frame  The GGRF is needed to measure crustal velocities and consequently inform decision makers about seismic hazards  The GGRF is needed to measure global sea-level change

ggim.un.org “Positioning geospatial information to address global challenges” Sea Level Rise  Much of the world’s population live in the coastal zone  Rising sea levels and storm surges will have significant impacts on many of our coastal towns and cities  Understanding the risks to infrastructure and private property is important  Geodetic Infrastructure underpins our understanding of sea level change and its impacts

ggim.un.org “Positioning geospatial information to address global challenges” Sea Level Rise  GGRF is important for  Sea-wall construction  Managing development in flood prone areas  Improving building codes and practices  Improving drainage and flood mitigation construction Tuvalu meteorological office

ggim.un.org “Positioning geospatial information to address global challenges” Global Geodetic Reference Frame  Significant economic benefits arise from the use of GGRF and satellite positioning  This presentation will provide some benefit examples from Australia  These examples are transferable to all other countries, developed or developing

ggim.un.org Positioning geospatial information to address global challenges Economic Benefits of Positioning: Agriculture Images: Tim Neale, Precision Agriculture, 2015  Australian agriculture sector contributes 2-3% of GDP  Applications: precision agriculture  Impacts  Upto 25% reduction in fertiliser  Upto 50% reduction in diesel fuel usage

ggim.un.org Positioning geospatial information to address global challenges Economic Benefits of Positioning: Mining  Applications  mine surveying, autonomous mining, machine guidance  Depending level of automation  productivity gains can include labour force reduction from between 5% and 50%,  productivity gains ranging between 1% and 15%

ggim.un.org Positioning geospatial information to address global challenges Economic Benefits of Positioning: Construction  Applications: surveying, machine guidance and asset management  Require an accuracy of around 2 cm  Savings 10% to 20% achieved with machine guidance

ggim.un.org “Positioning geospatial information to address global challenges” (The Allen Consulting Group, 2008) Precise satellite positioning technology could potentially add up to 2.1% to Australia’s GDP by 2030 through productivity gains in mining, construction and agriculture alone Coordinated investment Economic Benefits of Positioning

ggim.un.org “Positioning geospatial information to address global challenges” Key Messages  Satellite positioning is vitally important to the economy, environment and society  The ability to position both information and objects accurately will be an increasingly important driver of prosperity  The GGRF underpins global change science and supports improved disaster risk reduction  With modest infrastructure investment all countries can obtain the benefits of and contribute to the GGRF
