Solar System Interest Group

This interest group is chaired by BaptisteCecconi (appointed 2017-05-14).


The Solar System Interest Group (SSIG) will aim at reviewing IVOA standards in the scope of Solar System sciences. The SSIG will work with all IVOA working groups to review, assess and propose IVOA standard adjustments for Solar System sciences. The standard assessments, reviews and potential evolutions will be proposed to relevant working groups keeping in mind two main ideas:

  • re-use of IVOA standards with as little changes as possible
  • modifications with a topical scope as wide as possible

Mailing List

The SSIG mailing list is available here. Register to participate or receive news and updates.


The preliminary IPDA-IVOA interaction study conducted in 2015 highlighted the following focus topics for the SSIG:

  • Standard List Coordinate Systems and Reference Frames. Link with NASA/NAIF SPICE system for possible implementation in STC.
  • Standardization of planetary observation geometry (linked with the OGC/GIS community), covers semantics, data model and implementation
  • Consolidation of EPN-TAP (Solar System flavor of ObsTAP, developed by Europlanet/VESPA). Adjustments of Table Access Protocol (TAP) and Astronomical Data Query Language (ADQL). Future IVOA Standard ?
  • Standard List of Ground Observatories and Space Missions.
  • Work with Astronomy Data Centers to enhance the distribution of their planetary products (ESO, CADC, HST…)
  • Cross-matching of registries (IVOA, SPASE, NASA/PDS…), at least on Dublin Core.
  • Promoting and extending SAMP (Simple Application Messaging Protocol), adding new message types (e.g., PDS3, PDS4, netCDF, HDF5…)
  • Reviewing and extending IVOA Data Models and Semantics to Solar and Planetary Sciences.
  • Proposing new serialization examples for IVOA standards with file formats used in solar and planetary sciences (HDF5, netCDF…)
  • FITS keyword standardization for Planetary targets (ongoing work within VESPA and USGS)
  • VOEvent for “Space Situational Awareness” (SSA) for Earth and planetary events.
  • Exoplanetary sciences (using planetary standards for exoplanetary data to enhance comparative analyses)
