  • Space geodesy metadata technical interchange meeting (August 2015)
    A technical workshop was held at UNAVCO in Boulder CO in August 2015 to identify the best course of action toward standards in geodetic metadata. The goal was to build a broad understanding of the metadata issues and move forward towards a technical solution within the space geodesy community that could be utilized by the GGOS Portal among other applications. Attendees discussed IAG services and GGOS requirements. Various metadata models were also presented and discussed, including eGeodesy developments in Geoscience Australia/New Zealand, ISO standards, NASA’s EOSDIS common metadata repository, and on the IGS site log manager. Presentations from the workshop are available on the CDDIS ftp site. Summaries of the meeting and follow-up telecon are also available.
  • GGOS Network
    • Call for Participation (CfP): The Bureau developed and issued a Call for Participation in the "Global Geodetic Core Network: Foundation for Monitoring Earth System" for the development, implementation, and operation of the GGOS geodetic core network (chair support letter).
      The long term goal of the Core Network is to implement a global network of ground-based space geodetic sites that provide 1 mm and 0.1mm/year quality measurements to satisfy the GGOS Scientific Objectives (GGOS 2020). The network will evolve over time with new technologies replacing legacy technologies and new sites being established. The quality of GGOS data products will improve as the network progresses. All fully operational sites will continue to play a crucial role as this evolution proceeds. The Call for Participation is still valid and you are invited to participate!
    • Responses to the CfP: A total of 19 submissions (summary) were received covering 46 sites that included legacy core cites, legacy/new technology technique sites, core and technique sites under development, and sites offered for future participation.
  • GGOS Infrastructure Implementation Plan
    The Plan defines the process by which we determine the extent of the needed infrastructure, including the scope and specification of the network, conditioned on the
    existing or plausible technology available.
  • Site Evaluation reports 
    Within the context NASA’s Space Geodesy Project, several sites were evaluated as potential core sites. These documents are available from the SGP website.
  • Other reports
    • The TLS (Terrestrial Laser Scanner) Workshop was held at NASA GSFC, September 08-10, 2008; a summary report (pdf/6130 KB) has been issued.
    • A Bureau summary report was presented during the GGOS Meeting in San Francisco in December 2012.
  • GEO activities
    • This GGOS project will contribute to the Global Earth Observation System of Systems (GEOSS).
