The California Spatial Reference Center (CSRC), in partnership with surveyors, engineers,
GIS professionals, the National Geodetic Survey (NGS), the California Department of
Transportation (Caltrans), and the geophysics community, has developed a plan to
establish and maintain an accurate state-of-the-art network of GPS control stations
necessary to meet the demands of government and private businesses for a reliable spatial
reference system in California.
The CSRC infrastructure will aid public health and safety, assist in the protection and
preservation of natural resources, and improve the productivity of government and private business.
CSRC is located at the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics (IGPP)
at UCSD's Scripps Institution of Oceanography (SIO).
Previous issues for RTCM data streams for Trimble and Sokkia RTK users have been resolved. See updated CRTN Access file
Thank you for participating in the SOPAC 20th Anniversary Questionnaire.
We have closed the questionnaire and had a successful turnout with 141 SOPAC users completing the survey (202 SOPAC users started the survey).
We greatly appreciate your support. Your responses help us to seek out funding for SOPAC web services and products and are important to keeping SOPAC operational.
We will be tabulating the results and making them available to those who are interested.
Periodically, we will ask for your help again and will include your feedback in annual reports and grant submissions.
Please be responsive to our email requests and future questionnaires, as well as our requests for references of your publications with SOPAC data.
