ggim.un.org Positioning geospatial information to address global challenges UN-GGIM: Arab States WG3: Geodetic Reference Frame Zuheir Altamimi, IGN France Second meeting of UN-GGIM: Arab States, Algiers, June, 2015 Why a GGRF is needed ? UN GA Resolution on the GGRF Current Status of the GGRF (ITRF) ITRF Contributions of Arab States ? From ITRF to Regional & National Reference Frames WG3: Suggested key points for discussion: Technical and organizational aspects

ggim.un.org Positioning geospatial information to address global challenges Why a GGRF is needed ? Geodesy: Quantification of Earth changes in space and time, expressed in (related to) a Global Geodetic Reference Frame (GGRF): Sea Level variations in space and time Tectonic Motion & crustal deformation Dislocations due to Earthquakes Tsunamis and Natural Hazards, rescue and safety of life Positioning, locations & navigations (ocean, land, air & space) National territory & land managements, precision agriculture, …

ggim.un.org Positioning geospatial information to address global challenges Current Status of the GGRF The currently adopted GGRF in use today: The International Terrestrial Reference Frame (ITRF) Implemented by multiple geodetic techniques Developed by the IAG and its technique services More than 600 sites globally distributed Based on the “best-effort” principle, for the interest of science & societal applications: ~200 institutions around the World And at the regional/national level: Almost all regional, national (but also global, e.g. WGS84) reference frames are aligned to & compatible with ITRF Densifications by Regional/National Permanent GNSS(GPS) networks.

ggim.un.org Positioning geospatial information to address global challenges Critical issues inhibiting the GGRF enhancement Aging geodetic instruments, inhomogeneous network distributions & poor number of high quality instruments: ==> * critical for the GGRF accuracy * need new generation systems Based on the “best-effort” principle ==> * Need high level mandate to sustain the GGRF *Inter-governmental cooperation => economical benefit Many countries have poor access to the GGRF ==> * provide technical assistance to countries in need & build modern geodetic infrastructure ==> improve interoperability of geospatial data

ggim.un.org Positioning geospatial information to address global challenges Key Points of the UN GA Resolution Development & sustainability of the GGRF Enhance global cooperation: –No one country can do this alone –Multilateral cooperation –Provide technical assistance for countries in need Implement open sharing of geodetic data, standards and conventions, on a voluntary basis Commit to improving & maintaining national geodetic infrastructure  Improve the GGRF Develop outreach programs

ggim.un.org Positioning geospatial information to address global challenges From ITRF to Regional Reference Frames Purpose: –Geo-referencing and positioning applications (not designed for science applications, but could be!) –Unification of geodetic/mapping applications within a continent or a region, without need for transformation Requirement: no time variations or velocities in site coordinates –Imposed by law/decree –Easy to handle by surveyors for centimetric/decimetric precision applications GNSS(GPS) is the tool today to access the ITRF, via publicly available IGS products for > 600 reference sites
