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

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?

“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” P Reconned P Has to be relocated onto Coyote Mountain Block P Relocated due to nearby subsidence P Relocated for science goals P On hold due to lengthy permit process with Navy and security issues P-494 – Built P Permitted, Construction scheduled for Fall P Permitted but principal is considering backing out due to architect concerns P Relocated to nearby airport due to close proximity to P496 - permit pending P-498 – Built P-499 – Built P Built P Built P Permitted, architect objects, may have to relocate P Built P Relocated due to rejected permit and Built at Red Hill P Relocated for security P Relocated out of subsiding area - construction scheduled for Fall P Reconned P Reconned P Permitted, Construction scheduled July 21 P Permitted, Construction scheduled July 20 P Permit submitted P Permitted, Construction scheduled for Fall P Built P Relocated for science goals P Relocated and Built P Built CSRC Activity on behalf of PBO

NAVD88 Leveling for GPS Cecilia informed me this morning that Riverside and CSRC Leveling projects have been blue book’d. 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.

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.

Education and Outreach Examples Caltrans Task Order Kick Off Meeting GPS Users Group Meetings Northern San Joaquin Valley Project Meeting with Caltrans at Stockton and Fresno Offices CLSA Conference: CLSA Workshop, exhibit booth State of NGS 2006 seminar in Riverside on April 13 Working with LA City to level to CGPS sites in LA area that are part of LARTN Working with RV Co. and RCFCD to include/upgrade CGPS for MWD/RV RTN Coordinated with PBO for upgrades to several MWD CGPS sites Working with Bill on CLSA and Sacramento seminars Assisted several users with the CRTN; word is getting out and they are asking how to access the data, etc.
