Keep collecting GPS on BMs

California’s Citizen Geodesist Philip Melcher reminds us that although "the opportunity to submit observations to NGS’ NAPGD2022 campaign has passed on Feb 29th, you can submit GPS on BMs. There are still hundreds of thousands of bench marks across the US that have never been observed by GPS. These old marks might be passé, but sharing solutions isn’t. You can still share your solutions to NGS or submit recoveries wherever you find one.

Almost 59,917 marks (Ed. I think Philip did 10,000 of these) were shared on existing NGS marks and 16,393 non-NGS marks to the IDB to date since the program started. I highly encourage you to keep sharing your solutions as I believe David C. Garcelon mentioned in the context of boundary surveys that resurveys brings history to the front.”
