The chapter holds monthly meetings for all of its members and others interested in land surveying. You can find information on the next meeting of the CLSA Central Valley Chapter, and on past meetings of the CLSA Central Valley Chapter from this web site.
The chapter occasionally hosts, participates in, or promotes special events. This could be annual land surveying conferences in our area, classes and seminars, or special projects. Visit the special events web page for more information.

Continous GPS Stations
A message from Rob McMillan:
Below are excerpts of emails from Unavco's Chris Walls and Sharon Williams of the National Science Foundation. Please read and respond to the survey at the link below. This is particularly critical if you perform any of the following:
- Static GPS surveys
- RTK GPS surveys using a virtual reference network (CSDS, Leica, Topcon, AZGPS, OCRTN, CVSRN, etc.)
- Surveys tied to NGS control (the National Spatial Reference System (NSRS))
- Surveys tied to the California Spatial Reference System (CSRS)
- Surveys in state plane coordinates
- Surveys tied to NAVD88 datum
- Surveys tied to tidal datums
- Surveys in areas of tectonic activity
- Surveys using HTDP
- Monitoring surveys (structural monitoring, dam deformation, etc)
This infrastructure also can support advancements in earthquake early warning, precision agriculture, automated machine guidance, autonomous vehicles, positive train control, and more.
The future performance, capabilities, and station count of the Plate Boundary Observatory is at a crossroads. UNAVCO is currently developing budgets and plans for operating the network beyond 2018 including scenarios of reduced network density. If you rely on UNAVCO-provided PBO data then I recommend you make it clear what the uses are, what the regions of interest are, and even specific stations or data type (i.e. 1Hz, 5Hz, 15s, Met, real-time, seismic etc...). Please forward to collaborators who will miss the data if resources are not available.
PS - the survey will take 5-10 minutes, contrary to what is described below. Thank you for your participation.
Dear UNAVCO Users,
At the request of the National Science Foundation (NSF), the Science and Technology Policy Institute (STPI) has been asked to solicit feedback on the activities, products, and services provided by UNAVCO. NSF, UNAVCO, and STPI would all appreciate your time and response to this survey. The survey itself should take between 20-30 minutes. Your participation is completely voluntary. Your responses will not be shared individually and will not impact your relationship with NSF or UNAVCO. STPI is an independent, Federally Funded Research and Development Center and will be collecting and analyzing all responses. If you are a UNAVCO member or RESESS participant and have received a previous invitation to this survey, please disregard this email. We apologize for multiple survey invitations, but we are hoping for feedback from as many individuals as possible. Please feel free to contact Sharon Williams at STPI (email@example.com; 202-419-5411) or Russell Kelz (firstname.lastname@example.org; 703-292-4747) at NSF if you have any questions or concerns.
