NGS Contributes to International Geodesy Working Groups


Friday December 04, 2020


NGS employees represented the U.S. in the virtual plenary meeting of the Sistema de Referencia Geocéntrico para las Américas (SIRGAS). SIRGAS is an organization of scientific and national geodetic agencies in the Americas, established in 1993 to modernize legacy national geodetic data systems with a unified geocentric reference frame. The SIRGAS Reference Frame was adopted by the United Nations Global Geospatial Information Management – Americas Regional Committee, which includes the U.S. While modernizing the National Spatial Reference System, NGS intends to closely coordinate and integrate with SIRGAS. NGS staff are highly involved in the SIRGAS working groups on geometric and vertical reference frames. The U.S. has also led in the working group on education, training, capacity building, standards, and nation-to-nation dialog. Newly revised SIRGAS statutes — largely championed by the U.S. — were agreed to during the Directing Council meeting and will meet U.S. needs for the foreseeable future.
