Pathway to 2022 - The Ongoing Modernization of the US National Spatial Reference System
Refreshments Sponsor: Still Open
In 2022, the National Geodetic Survey (NGS) will be replacing the US horizontal and vertical datums (NAD 83 and NAVD 88). We will discuss what activities are being undertaken to ensure a smooth transition. Also, NGS is currently in the process of producing a much-improved national hybrid-geoid model in 2018, to replace GEOID12B.
We will also discuss the history of the North American Datum of 1983 and the North American Vertical Datum of 1988, their relationships to other reference frames, and the reasons for their ongoing evolution. This presentation will also provide information on the National Geodetic Survey's powerful Coordinate and Transformation Tool (NCAT), capable of 3D transformations between all commonly used datums.
