[IGSMAIL-8633] Technical Workshop on Storage and Exchange Formats for GNSS Data - Feb 24-26, 2026 - Portugal

[Rui Fernandes]

Dear colleagues,

We invite active contributors to a *Technical Workshop on storage and exchange 
formats for GNSS data* on 24–26 February 2026 in Coimbra, Portugal. The workshop 
is co- organized by EarthScope (USA), Geoscience Australia, EPOS (Europe), and 
the IGS Infrastructure Committee. The final afternoon will be dedicated to 
prepare a white paper that sets out technical recommendations and an 
implementation roadmap for common GNSS data formats.

*Scope and goals*
     •    Consolidate existing technical requirements for next-generation GNSS 
data and metadata across archives and processing centres, including use of cloud 
storage services.
     •    Evaluate practical options beyond the file-per-session convention, 
including chunked and columnar containers (e.g., TileDB, Iceberg, Parquet, 
Zarr), with attention to layout, compression, indexing, and scalable access.
     •    Define interoperability at the format and API layers to enable 
reliable data exchange and tooling across organisations, with a view toward 
federation of archives and services.
     •    Produce a white paper with recommendations and an implementation 
roadmap toward common formats.
*
Who should participate*
Engineers and researchers working on GNSS data formats and I/O software; people 
responsible for GNSS archives and storage systems; and operators of real-time or 
post-processing systems. This is a working meeting. Attendees are expected to 
contribute substantively during the sessions and help deliver the white paper 
and follow-on implementation tasks.
