California Spatial Reference Center


La Jolla, California

Minutes (February 20, 2001)

I. Opening (Bill Young)

  1. The meeting began at 9:30 AM in La Jolla on the campus of Scripps. Self- introductions were made by everyone present.

  2. Minutes from the Executive Board meeting of November 19, 2000 were approved. The minutes will be approved by the e-mail notification process for all future meetings.

  3. The agenda was reviewed. No new items were added.

  4. New members to the Council were introduced by Bill Young. They included:

Mark Turner, Caltrans

Meghan Miller, PANGA

Patrick Tami, CLSA

Scott Martin, DWR

Members of the CSRC Executive Council will visit Caltrans, State Representatives and other California agencies beginning tomorrow with scheduled meetings throughout the State.

The Board has written thank you letters for all those who wrote their congressmen requesting funding for CSRC.

II. Director's Annual Report (Yehuda Bock)

  1. Yehuda reviewed the mission statement and history of funding to this point for the CSRC.

  1. He covered staffing as it currently exists, describing the use of SOPAC staff to this point in the organization's history. The existing balance is about $80,000. Expected income for FY2001is $1,000,000 from the NGS and $137,000 from Caltrans.

Major CSRC past projects included the HPGN re-adjustment for Caltrans involving publishing new coordinates and velocities for the State.

The Hector Mine Earthquake in October 1999 that affected the 1998 stations for the eastern Mojave Desert area was completed. A field survey of 61 stations in May 2000 for all stations with a greater than one cm of movement was performed.

A total of 241 stations were actually analyzed, including all existing CORS on-line at the time, using GAMIT and GLOBK software packages. This added many more stations to the HTDP velocity model than previously existed.

Accuracy for the network equaled 3mm in the horizontal and 9mm in the vertical. Coordinates were computed in ITRF97 and NAD83. Coordinates and velocities will be published on the CSRC and NGS websites by March 1st, 2001.

  1. The main issues remaining for the CSRC is to achieve a yearly funding goal of $ 3,000,000. The majority of future funding should be 'continuing support' instead of 'project specific' support. Continuing support allows for the establishment of the operations and maintenance of the entire CORS network, while specific project support does not.

Don stated his role as Coordinator continues to facilitate interplay between surveyors and GIS specialists within California on the needs and role of the CSRC. Future presentations include the CLSA/NALS/ACSM panel discussion about the CSRC role in California.

Bluebooking reform between CSRC and NGS is another issue to be evaluated.

IV. NGS Comments (Charlie Challstrom)

Charlie described the long road the CSRC has been on to get to this stage of its development. Work continues on guidelines for California CORS. The NGS wants to expand CORS applications for public use in the future. Height Modernization is a NGS focal point nation wide. Julian Dixon was a major supporter of this program and it's funding and will be missed.

Charlie described the $1,000,000 by Congress to the CSRC as a 'soft earmark'. This means overhead costs through NOAA of 5% is very likely. Also, international travel costs are being cut in the federal government.

Partnerships with local government is understood and supported by the NGS. The need for clear strategies to continue funding from Congress is very important. Looking for new supporters in both state and federal levels is also important.

  1. NGS Coordinator Comments (Marti Ikehara)

Marti emphasized the need for quick responses to the proposed CSRC budget be made to her as soon as possible so that adjustments to it wouldn't slow down the current CSRC funding campaign.

  1. SCIGN (Ken Hudnut)

Ken reviewed the SCIGN project and funding history. SCIGN, the Plate Boundary Observatory (PBO), and the budget disconnect between the projects were described. The PBO won't fund SCIGN. The NSF and USGS do not want to extend funding for SCIGN into the maintenance phase of the program. SCIGN needs the CSRC to find ways to fund and maintain this system with long-term funding sources.

Geodesy is now feasible in a network mode similar to the way seismology has been for some time. SCIGN is an example of the 'best geodetic method ever devised' for achieving PBO goals.

Funding for PBO is questionable due to the new administration in the White House. The USGS does not appear to have the budget to maintain SCIGN into the future (one year at current spending rate). The system is a $16,000,000 investment.

VII. BARD (Mark Murray)

BARD has 50 stations, most in the San Francisco Bay area with an initial investment of $500,000. Most stations piggy-back on existing seismology stations for power and telemetry. BARD is looking to expand in the Parkfield area and Bay area with an additional 17 stations, including GPS, strainmeters and seismometers. No continuing support for maintenance is currently budgeted.

  1. CSRC Bylaws (Larry Fenske/Susie Pike)

IGGP is the department that CSRC will be recognized and organized under within Scripps Institution of Oceanography (SIO). CSRC Coordinating Council will be organized under a 'Support Group" identification. Approval is likely from the chancellor in the next six weeks.

  1. Public Resources Code (Michael McGee)

Section 8801-8819 of the Public Resources code was reviewed for proposed language changes to include CSRC definitions and partnership language that ties CSRC to the NGS. The consensus was to pursue the recommended changes presented.

  1. CSRC Funding (Bill Young/Suzanne Lawrence)

The letter writing campaign of last year was very successful, especially coming from people in the private sector. The telling of actual projects that utilize CSRC information should comprise the letter writing campaign this year. Suzanne will help define the targets these letters should be addressed to this year (legislature and agencies). This should be known next week after the tour of the State Departments, agencies and legislature. Suzanne will assist in distilling letters down to brief summaries and post an example letter for general use.

  1. Congress $1 Million Allocation (Yehuda Bock)

Eight tasks are purposed by the CSRC for the Federal allocation of $1 million for FY2001. They include:

  1. CORS Data Portal - Provide a full service online data portal for all metadata for all CORS sites, including antenna heights with diagrams, height definitions, reference points or marks definitions (ARP), published concise coordinate sheets for all sites. Proposed budget is $150,000.

  2. Height Modernization - Define vertical reference frame, assign orthometric heights, provide leveling data to CORS, establish specifications for surveyors to use these heights. Proposed budget is $200,000.

  3. California Spatial Reference Network Master Plan - Prepare a plan to identify state gaps for existing horizontal and vertical networks. Report on all known monuments, both traditional and GPS. Make recommendations for future installation. Proposed budget is $50,000.

  4. Height Modernization (southern San Francisco Bay) - Add 30 new stations in the Bay area including tidal benches and BARD stations. Some contracting is likely for this project. Proposed budget is $200,000.

  5. Southern California Real Time GPS Network - Develop and demonstrate real-time 3D GPS network capability utilizing cellphone technology for construction staking and other surveying applications. Demonstration system would be in Orange County. Proposed budget is $300,000.

  6. Height Modernization InSAR - Demonstrate InSAR technology and its effectiveness for monitoring land subsidence. Provide draft guidelines and training material. Provide technical consultation for InSAR projects. Proposed budget is $100,000.

  7. California CORS Densification - Install four CORS stations in Central Valley area including: permits, purchase, installation, and testing. Proposed budget is $150,000.

  8. Masters of Science Program Development - Develop Masters in Spatial Referencing and Geodesy at Scripps for the Fall 2002 quarter. Could involve developing some modules for the Internet. Proposed budget is $100,000.

XII. Election of Officers and Executive Committee Members (Bill Young)

A sample ballot was distributed for voting on the following officer positions: Chairperson, Vice Chairperson, and Treasurer. The secretary position was elected at the last annual meeting. Four at-large Executive Committee members were also presented on the ballot. There were no write-in candidates proposed. The following list the results of the ballot:

Chairperson Greg Helmer

Vice Chairperson John Canas

Treasurer Larry Fenske

Executive member Dave Stone

Executive member John Casey

Executive member Nancy King

Executive member Fred Wong

There was a temporary adjournment for CSRC dedication and luncheon that followed. Meeting reconvened at 2:00 pm.

  1. Remaining CSRC Issues

The Council discussed contracting issues related to the private sector. Many issues were discussed and debated. It is understood that CSRC will have to abide by the contracting laws that governor UCSD. Susie will find out what these guidelines are so they will be clear to the Executive Committee and Coordinating Council of the CSRC. Discussion ensued on issue of whether anyone who currently serves as a officer or on a committee should be excluded from bidding. There was no consensus at this time. It was acknowledged any appearance of favoritism to the marginal supporters of CSRC, especially at the outset of this new contracting phase, would not be beneficial to the future support of the organization.

Discussion on what type of response the Master's program would create followed. The Program will reside in the Earth Sciences Department. The GRE exam would be required for new students. The program could be completed in one year with 36 quarter-units required. This equates to about nine classes, a few of which already exist within the University.

It is possible to get some engineering and surveying graduates from California programs, though the numbers would be small at first. Many thought the majority of students would be from the thousands of existing GPS users around the country, especially in California. With this in mind, some suggestions for program flexibility were proposed including:

These options will be discussed further by staff and the Board at a later date. The meeting was adjourned at 3:45pm.
