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) Source: Darrell Bain, Caltrans District 6, Fresno
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.

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. Enhancement of projects page on the CSRC web site. See http://csrc.ucsd.edu/projects/. 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?
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)
