FY’04-’05 Summary
FY’04-’05 Tasks
Annual report submitted to NGS on 1 August, 2005
1. Education and Outreach
Objectives
• Keep CSRC members informed through regularly scheduled
meetings (Coordinating Council and Executive Committee).
• Inform others on the objectives and activities of CSRC by
participating in local meetings, conducting seminars, making
presentations, and make a presence at professional conferences.
• Support public resource code (PRC) legislation for orthometric
(vertical) and geodetic (horizontal) datums.
• Perform advocacy efforts to improve California’s spatial reference
system, by informing and discussing with public agencies (local,
state and federal) the benefits of, and funding needs for, a modern
California spatial reference system.
• Respond to general, day-to-day user inquiries in a timely manner.

3. CGPS Operations and Maintenance
• Partial support for the operation and maintenance of the existing CGPS sites in
California, which form the backbone of the California Spatial Reference
Network (CSRN), including site maintenance, data download, data archive, and
data analysis.
• Installation of of new Earthscope PBO stations by UNAVCO, and the funding
of the NSF Nucleus project, which will transition over the next 3 years the
operation and maintenance of many SCIGN, BARD, BARGN, and PANGA
sites to PBO.
• CSRC and its partners (e.g., Caltrans, MWD, and southern California
Counties) have been assisting PBO field engineers with obtaining land-use
permits for PBO sites throughout California.
• Southern California Earthquake Center (SCEC) has recently announced its
decision to cease further support for operation and the maintenance of SCIGN.
SOPAC continues to receive funds through SCEC during the transition to PBO.

CVSRN Pilot Cost Recovery
Savings 1:
1.5 crew hours/day
Time the crew spends at the beginning of an RTK survey, selecting the control point where the
base station will be placed. This process is reversed at the end of the survey. The time lost to
this activity is a minimum of 1.5 crew hours a day. It is sometimes necessary to perform this
action multiple times in one day’s survey operation. Using the CVSRN, the crew will navigate
directly to the job site, set up the roving receivers and begin their survey.
Savings 2:
1.22 crew hours/day
Time spent by one crew member remaining at the base station to protect against its loss and to
correct any equipment malfunctions. Using the CVSRN eliminates the need for this activity.
Savings 3:
1.48 crew hours/day
There is an additional savings gained from the use of the CVSRN. There is no longer a need to
establish project control within the CVSRN area. Currently our crews spend an average of four
crew days establishing survey control for each new project. This includes recovering first-order
corridor control, setting project control monuments, and tying the project control monuments to
the first-order monuments horizontally.
Estimated Cost Recovery Pilot Project: 5.44 months (investment of $225,000)

4. NAVD88 Leveling for GPS
This task included
funds for additional
out-sourced leveling
projects in southern
California.
These
funds have not yet
been
spent
(see
financial report), and
are being applied to
one of the three
CSRC subcontracts in
FY06.
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 with Riverside Country Flood Control and Water Conservation District
and City of Los Angeles.

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”

7. Improve Geoid Model
This task is an ongoing one and is related to the several height
modernization projects that the CSRC has contracted out to
the private sector, and the resulting network analysis
performed by CSRC consultant Mike Potterfield. For
example, in the San Joaquin Valley project (task 5) in this
fiscal year we were able to compute an improved geoid
model based on differential leveling circuits, ties to NAVD88
benchmarks, GPS heights and a gravimetric geoid model. The
details are discussed in the report of the SJV height
modernization project.
8. Management and Administration
Financial reporting was improved in this fiscal year on the advice of
the Executive Committee. Monthly reports are provided by the third
Wednesday of each month.
The Fall Coordinating Council Meeting was held at Scripps on
October 22, 2004.
The Spring Coordinating Council Meeting was held at PG&E
headquarters in San Francisco on May 17, 2005 (presentations can
be found at http://csrc.ucsd.edu/general/presentations.html.

CSRC Facilities. The SOPAC/CSRC staff continued to upgrade and
make changes to the Data Center.
FY’05-’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?

Financial Report
FY’05,‘06 Appropriations & FY’05-’06 SOW
Nov. 21, 2004: Received news that FY‘05 Height Mod funds to California cut by
50% to $500,000.
 Dec. 22, 2004: Included recommendations for projected CSRC budget surplus.
 January, 19, 2005: Significant SIO efforts to undo allocation fail, including
discussions with various Congressional offices and Director of NOS (Richard
Spinrad). NGS agrees to provide full $500,000 to CSRC (no 10% tax) and to
consider additional projects up to $100,000.
 February 28, 2005: Final SOW and Budget prepared for NOAA ($500,000) and
submitted to JIMO. These funds have just now been received at SIO.
 We are trying to leverage the FY’05 shortfall to increase our FY’06 allocation to
make up the shortfall, and set a precedent for future years. We are also making
a new effort at the state level. FY06 continuing resolution runs to 18 Nov.
 During last conference call, NGS requested FY’06 work plan by 1 Nov.
 Budget surplus is being addressed through efforts of EM and EC, based on
recommendations from work plan committee and Director. Three external
projects are in the works in FY’05-’06.
 Expected surplus at end of FY’05-’06 is $100K (the reserve fund)
