I can't get to it right now, but the new date would be found in the update file. So this would only occur on cells with updates. If I open an update file (.001+) in a text editor, I see the date on the second line. I'm just using the first cell found @ www.charts.noaa.gov/ENCs/ENCsIndv.shtml

ah - the situation you're describing is subtly different. That's when you have two 8211 fields concatenated together, so e.g the DSID/DSSI are concatenated into a single 8211 record at the head of a standard S-57 ENC. What I'm talking about is when a single 8211 field has repeating subfield

The multiple field/subfields - I think gdal already does this for S-57 on DSID. It just prefixes the subfields with the field name. However -side note: it seems the DSID_ISDT (issue date) is incorrect, it just has the same value as DSID_UADT (update application date). On Thu, Aug 30, 2018, 4:27

The biggest work item for S-100 compatibility would be an update to the GDAL/OGR drivers for iso8211 in order to parse the S-101 iso8211 encoding. S-101 is the candidate replacement for S-57 ENC data - so, at some point all of NOAA's S-57 marine data will be available as S-101 datasets too.

All, I've committed in GDAL master various improvements in the BAG driver, around two main directions: - read support for variable resolution BAG, with resampling and interpolation options - creating of (single resolution) BAG files from other GDAL datasets Updated documentation available at

I'd be happy to connect anyone with the folks at NOAA, CCOM-JHC, and elsewhere who have been participating in drafting S-10x. I only sat in on a few of the meetings long ago. Specs should eventually end up here... https://www.iho.int/iho_pubs/IHO_Download.htm#S-100 On Thu, Jul 5, 2018 at 10:43
