Upcoming site log format changes
Please be notified that following a decision taken by the IGS in consultation with regional GNSS networks, there will be some changes to the site log format :
- Adoption of the 9-character station identifiers in site log file names (currently already in use in M3G) and inside section 1 of the site log:
Four Character ID : (A4) --> Nine Character ID : (A9)
Four Character ID : BRUX --> Nine Character ID : BRUX00BEL
- Substitution of “Country” with “Country or Region” in section 2 of the site log. The current value of this field will also be replaced by its corresponding alphabetical three-character (Alpha-3) ISO-3166 country/region code.
Country : --> Country or Region : (A3)
Country : Belgium --> Country or Region : BEL
All changes are documented in https://epncb.oma.be/pub/station/general/blank_v2.0.txt and https://epncb.oma.be/pub/station/general/sitelog_instr_v2.0.txt.
In practice, as a first step, from June 5, 2024
- A new directory https://gnss-metadata.eu/data/station/log_9char/ will be created to store the site logs in the new format.
- The directory https://gnss-metadata.eu/data/station/log/ which will remain unchanged.
- Site logs uploads will be allowed in both the old and new site log format.
- The reformatted site logs will be accessible through the API V1.4x (https://gnss-metadata.eu/v14).
- The API V1.3.x (https://gnss-metadata.eu/v1) will remain unchanged.
In a second step, at a date still to be determined
- We will move the /log_9char directory to the current /log directory on M3G.
- How (and if) these site log changes will affect the GeodesyML format has not yet been decided by the IGS. As soon as a decision has been made, we will inform you.
