Help With California Central Valley Control Network 2.0

[Sunburned_Surveyor]

The CCVCN establishes survey grade state plane coordinates and NAVD 88 elevations on PBO stations and passive marks across a wide swath of Central California.

Between now and the end of the year I'll be working on the first major update to the California Central Valley Control Network. In this adjustment, I'll be adding some new PBO stations and trying to incorporate a bit of differential leveling. I've also learned a bit in the last couple of years, so I should be able to do a better job calculating NAVD 88 elevations for the points in the network.

Please let me know if you will be doing any static GNSS observations or leveling work in Central California before the end of the year. I'd love to incorporate your data into the network.

I'm also looking for high quality and easily accessible passive marks (control monuments) in Central California to include in the network. If you know of a good mark or have one you'd like to include, please let me know.

As a reminder, this is a volunteer project and the network is published online for free with all the supporting data (including raw files and TBC project files). You can reach out to me at sunburned.surveyor@gmail.com or lblake@hawkins-eng.com.
