The Nations Path Toward New Geometric and Geopotiental Datums in 2022

Tue, 09/02/2014 - 11:42am -- Anonymous (not verified)

The National Geodetic Survey’s (NGS) mission is to “define, maintain and provide access to the National Spatial Reference System to meet our nation's economic, social, and environmental needs." In simple terms, the NGS is, for the United States and its territories, ground zero for precise positioning information. From defining the nation’s spatial reference systems to free on-line services for survey position refinement, the NGS provides research and services vital to the surveying, civil engineering and GIS interests of the USA. This presentation will focus on the current datums of today and the work being done to prepare the nation for new geometric and geopotiental datums in 2022. The presenter is Mark L. Armstrong, PLS, Geodesist and NGS Oregon State Geodetic Advisor.
