CSRC Mandate

• Establish and maintain the California Spatial
  Reference System - CSRS.
• Provide the necessary geodetic services to
  ensure the availability of accurate, consistent,
  and timely spatial referencing data.
• Monitor temporal changes in geodetic coordinates
  due to tectonic motion, earthquakes, volcanic
  deformation and land subsidence.
• Establish the legal spatial reference system for
  California.

FY05-06 Research Objectives

• What is the proper observation mix to maintain a
  modern height network, and how should these
  measurements be optimally combined? Observation
  types include continuous GPS (CGPS), field GPS
  surveys at passive monuments, spirit leveling,
  and gravity surveys.
• What is the proper mix of geoid models and local
  corrector surfaces, in converting from
  GPS-determined geodetic heights to orthometric
  heights? What interpolation methods will provide
  the optimal corrector surfaces?
• Can we apply and enhance modern IT methods to
  provide timely access to height modernization
  information?
• How does one develop and implement a precise GIS
  for the purposes of height modernization?
• How can real-time (RT) CGPS networks, such as
  those being created in California, be best used
  to directly support height modernization and
  spatial referencing?

CSRC Activity on behalf of PBO
Hi Bob, Here is a list of action taken on sites
that you have done sitings for. Several have been
built (8), several more are slated for
construction (4-6) and more are in various stages
of the process. Several have also been relocated
for reasons ranging from rejected permits to
subsidence. This is par for the course. We would
definitely not be where we are at without your
significant efforts, Bob. Regards, Chris

NAVD88 Leveling for GPS
Cecilia informed me this morning that Riverside
and CSRC Leveling projects have been blue bookd.
Received from NGS.
Cecilia Whitaker continues to interact with local
government to arrange for similar surveys to be
conducted throughout S. California. In this
fiscal year, she worked City of Los Angeles.
