What? We get our own week! I hope you’re all basking in the glow of national recognition 🙂 Don’t forget to spread the word so people can join in the fun. The NSPS Young Surveyors’ Network is celebrating this week by challenging each other to participate in the push to get GPS on Bench Marks before the new vertical datum becomes a reality in 2022.
GPS on Bench Marks is an effort to add GPS coordinates to marks that make up the Nation’s height system, the North American Vertical Datum of 1988 (NAVD 88). These marks were part of historic geodetic leveling surveys, but they are often difficult and expensive to access. By adding GPS coordinates to these marks, NGS will improve future hybrid geoid models, and the information will also help create a tool to transform data between NAVD 88 and the new vertical datum. Visit the GPS on Bench Marks webpages to learn more.
And just for fun, here’s a rad historical photo:
