The Canadian Geodetic Survey provides the fundamental reference frame and standards for the measurement of latitude, longitude, elevation and gravity anywhere in Canada and monitors motions of [the] continental landmass in support of geomatics and geoscience. This geospatial reference frame underpins all activities where positions matter, enabling mapping, land surveying, water management and engineering activities in Canada. A growing community of research scientists rely on the program's precise positioning and gravity information to study changes in the Earth. The program is delivered by real-time analysis of global satellite data, supporting client services that enable Canadians to use global navigation satellite systems(e. g. GPS) for precise positioning, including heights above sea-level.  2, record 4, English, - Canadian%20Geodetic%20Survey%20%3A%20Spatially%20Enabling%20Canada

Les levés géodésiques du Canada fournissent les normes et le cadre de référence fondamentaux pour la mesure de la latitude, de la longitude, de l'élévation et de la gravité partout au Canada et surveillent les mouvements de la masse continentale en soutien à la géomatique et à la géoscience. Ce cadre de référence géospatial souligne toutes les activités où les positions sont importantes, ce qui permet des activités de cartographie, d'arpentage, de gestion de l'eau et d'ingénierie au Canada. Une communauté croissante de chercheurs s'appuie sur les informations précises de positionnement et de gravité du programme pour étudier les changements sur la Terre. Le programme est offert au moyen d'une analyse en temps réel des données satellitaires mondiales, en soutenant les services aux clients qui permettent aux Canadiens d'utiliser les systèmes mondiaux de navigation par satellite (p. ex., GPS) pour un positionnement précis, y compris pour les élévations au-dessus du niveau de la mer.  2, record 4, French, - Lev%C3%A9s%20g%C3%A9od%C3%A9siques%20du%20Canada%C2%A0%3A%20Le%20Canada%20%C3%A0%20r%C3%A9f%C3%A9rence%20spatiale

The National Geodetic Survey, our Nation's first civilian scientific agency, was established by President Thomas Jefferson in 1807 as the Survey of the Coast. Its mission soon included surveys of the interior as the nation grew westward. In 1878 the agency was reorganized and given a new name, the Coast and Geodetic Survey(C&GS), which it maintained until 1970. In 1970 a reorganization created the National Oceanic and Atmospheric Administration(NOAA) and the National Ocean Service(NOS) was created as a line office of NOAA. To acknowledge the geodetic portion of NOAA mission, the part of NOS responsible for geodetic functions was named the National Geodetic Survey.  1, record 17, English, - National%20Geodetic%20Survey
