In 2022, NGS will be replacing the US horizontal and vertical datums (NAD 83 and NAVD 88). This workshop is designed to discuss the need and process for these changes, as well as how these changes may affect users and what users can do to help prepare for these changes. Our journey will begin with a brief 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. As LiDAR is becoming much more prevalent within GIS products, we will also discuss the relationships of geoid models to various versions of NAD 83, and what can happen should these relationships be ignored.
