  • Ticket #5028 – Description

    initial v1  
    1 We are using the GDAL OGR S57 driver to extract data from the UKHO ENC data sets. We across a bug with the extracted data ( a lighthouse with lights not attached) and reported it to the UKHO. They carried out a thorough investigation and narrowed it down to a bug in the OGR S-57 handling of updates. Specifically OGR S57 was applying the update correctly to remove the light objects (4 of them) and add 4 new light objects but it was failing to update the lnam_refs field of the lighthouse (a LNDMRK object) with the lnams of the new light objects. I have attached the feedback from the IC-ENC team below. I have the GB301478 data set available for reproducing the bug with, please contact me for a copy.
