Planned Retirement of NAD83 and NAVD88

The National Geodetic Survey (NGS) plans on retiring the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88).  They are hosting a webinar at the 2015 Geospatial Summit.  More information below:

As a reminder, here are brief descriptions of these meetings:
At the Geospatial Summit, NGS will provide updates regarding the planned replacement of its two primary geodetic datums: the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88). The summit will be an opportunity for federal and state agencies, as well other constituents, to share their comments, questions and concerns regarding the new geometric and geopotential datums, which are planned to be published in 2022.

The annual National Height Modernization Program Partner Meeting allows state and university partners to explain the best practices they develop and challenges they encounter when determining accurate heights in their local regions or communities. The meeting is also an opportunity for stakeholders to express their requirements as NGS continues to develop geodetic models and tools in preparation for the replacement of NAD 83 and NAVD 88.
