Overview:

In 2022, NGS will be replacing the US horizontal and vertical datums (NAD 83
and NAVD 88) with a new datum. This new datum will be a combination
horizontal and vertical datum. This will allow you to reference a single
datum for both x,y and z values.

 

This free webinar is designed to discuss the need and process for these
changes, as well as how that affects geospatial professionals and their
access to these datums.  The journey will begin with a discussion of 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. We will also discuss the relationships
of geoid models to various versions of NAD 83, and what can happen should
these relationships be ignored.  Finally, we will discuss the need to
replace NAD 83 and NAVD 88, and what activities are being undertaken to
ensure a smooth transition.
