Hi
I have not checked the GDAL implementation but DSNM is an unneccessary
addition to the S57 spec to generate a (potential unique) GUID.
S57 spec has no GUID definition, IDs needs only be to unique inside a
dataset/ENC cell.
DSNM belongs to the dataset-wide DSID fields, see 6.3.2 in
https://iho.int/uploads/user/pubs/standards/s-57/20ApB1.pdf
Hello,
After reading this documentation concerning the S-57 driver :
https://gdal.org/drivers/vector/s57.html
I thought the attribute DSNM ( Dataset name) should be defined on all features,
no ?
But on the source code, the method S57GenerateStandardAttributes
(s57featuredefns.cpp) always attaches theses standard feature attributes :
GRUP, OBJL, RVER, AGEN, FIDN, FIDS but there is no mention of the DSNM
attribute.
Is it a mistake in the documentation? In the code? Or just a misunderstanding
on my side?
Thank you for your clarification,
