2018 GPS on Bench Marks Campaign Results
In February 2018, NGS released a list of approximately 5,800 priority bench marks where GPS data is needed to improve the modeling for GEOID18 and the transformation tool that will be created for NAPGD2022.
Approximately 2,469 GPS observations were submitted. We reached 45.5% of our nationwide goal, however the number of marks requested per state varies greatly, and many states have submitted observations on a much higher percentage of the requested marks.
Each bench mark observation is at least 4 hours in length, so every submission is a significant contribution toward improving the model. Thank you to all who have contributed data. Your efforts are helping to improve NGS models and tools in your local area!
