Bill93 Posted February 12, 2018 Share Posted February 12, 2018 (edited) The National Geodetic Survey recently published a list of those bench marks they most want professional GPS submissions (OPUS Share) on. That data will be used to help check or fit the 2018 geoid model and 2022 datum. Many were selected based on their location in areas needing more coverage, and without much emphasis on whether they had been recovered recently. Those marks having no recent recoveries would make excellent targets for everyone to hunt and submit. Anyone capable of OPUS Share GPS observations may want to use this list to select their targets. I have submitted sessions for 6 of the ones on that list, which I suppose raised their priority for a 2nd checking session. I chose those to be in areas with poor coverage in Geoid12b so they might have made the list anyway.
