Register for this Webinar

Webinar Description:

In early 2018, NGS released a list of priority bench marks where GPS data is needed to improve GEOID18, our next planned hybrid geoid model. NGS has also created a GPS on Bench Marks 2018 web map to help contributors know where we have the data we need and where we still need GPS observations.

In this webinar, you will learn about submissions on priority marks since early this year, what marks to prioritize before the August 31st deadline, and how future GPS on BM efforts will improve transformation tools in 2022.


Technical Content Rating:
