What’s happening in the world of IGLD?

While centered around 2020, the full IGLD (2020) update represents a significant, multi-year undertaking for CO-OPS. The new datum is scheduled to be implemented in 2027.

CO-OPS will regularly publish news stories during this period to provide updates on progress. You can access these stories on the right or via our CO-OPS news page. Check back periodically for more stories or subscribe to our IGLD (2020) email alerts by sending us an email at navigationnews@noaa.gov. Our email alerts are periodically generated and will contain the latest information about IGLD.
