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. </span><span style="font-size:9pt;line-height:107%;font-family:Helvetica,sans-serif;color:rgb(51,51,51)"><br>

<span style="background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial">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. </span><br>

expect in the future and ways that all geospatial professionals can adapt and
thrive in the new system.</span></span> <br></div><div class="gmail_default" style="font-family:"trebuchet ms",sans-serif;font-size:small"> <br clear="all"></div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><div>--------</div>David Alvarez <br><br>“THE FURTHER BACKWARDS YOU LOOK, THE FURTHER FORWARD YOU CAN SEE"<br><br>Winston Churchill</div></div></div></div></div>
