NSPS + NGS + RPLS Today = GEOID18
Join other RPLS Today members during 2018 National Surveyors Week by participating in the NOAA National Geodetic Survey's "GPS on Bench Marks" program! By participating, you are providing valuable data to NGS for the next GEOID18 hybrid geoid model as well as the 2022 Transformation Tool.
Here's a snippet from the NOAA NGS website:
Help improve the National Spatial Reference System (NSRS) by participating in the GPS on Bench Marks (GPS on BM) campaign. Your efforts will support the following objectives:
- Improve the next hybrid geoid model, GEOID18
- Improve the 2022 Transformation Tool , which will enable conversions to the new vertical datum in 2022 and be integrated into the NGS Coordinate Converstion and Transformation Tool (NCAT); and
- Help the local surveying community.

Thank you to StLouisSurveyor for starting this discussion!
The links pretty much explain it. However, if anyone else in your area (Miramar FL?) is working on it, teaming up or coordinating might be beneficial.
If you have GPS equipment to do 4+ hour static L1/L2/P measurements you can submit OPUS-S submissions on local bench marks.
If not, you can help by finding bench marks on the priority list and submitting condition reports (condition is how well it is holding its position, not cosmetics), along with updates for the to-reach instructions. If the data sheet has only coordinates scaled from a map, you can submit handheld recreational-grade (HH2) or mapping-grade (HH1) GPS coordinates to help users find it.
While doing it during a special week can coordinate publicity, submitting any time before August will be helpful for the next geoid model.
The Pennsylvania College of Technology chapter of the PSLS recently participated in the GPS on Benchmarks program.
We observed the "Scenic" benchmark along highway US 15 south of Williamsport PA.
Looks like a great one to do.
I was initially worried when I saw the triangle symbol, as most triangulation stations don't have good elevation data and that would mean it wouldn't be useful for GPSonBM. But I see on the data sheet it is a traverse station that has been leveled through, so all is well. First order, even.
I don't see your share solution on the site yet. Hope it processes well.
