In 2022, the National Geodetic Survey (NGS) will replace all components of
the National Spatial Reference System (NSRS), including NAD 83 and NAVD 88,
with a new system that is geocentric, time-dependent and not reliant upon
passive control. Every survey, map or geolocation created today will be
incompatible with the new system by as much as 4 meters, depending on where
in the United States you are working. This misalignment could apply to
every latitude and/or longitude and/or height in your work.

In order to assist users in understanding and adapting to the new system,
two technical reports were released by NGS in 2017, under the title
“Blueprint for 2022”, with a third, companion report in the works. The
first two reports provide the scientific and definitional aspects of four
new time-dependent terrestrial reference frames and their companion
“geopotential datum” (replacing and expanding upon the historic concept of
a “vertical datum”). The third report will focus on the user community and
how it can work within this new paradigm of time-dependent geodetic
control.

This talk will focus on all of the changes to expect in the future and ways
that all geospatial professionals can adapt and thrive in the new system.
