I also searched at http://www.s-57.com/ without success. I found the values by inspecting the object with opencpn as chart-viewer The s57 data are the official inland waterway maps from the german waterway administration. They are provided free of charge. (I'm a professional inland waterway skipper, we must use this data by low for ECDIS (chart display of AIS data) on all vessels longer than 20 m) e.g. Mittellandkanal https://en.wikipedia.org/wiki/Mittelland_Canal https://www.elwis.de/DE/dynamisch/IENC/download_commit.php?file=WW41_2018-06-22_0_318 or an overview at: https://www.elwis.de/DE/Service/Inland-ENC-der-WSV/Inland-ENC-der-WSV-node.html or an example without the hassel of extracting http://gpl.coulmann.de/tmp/1W7ML310.000 The chart holds river kilometers with not physically installed distance marks. I like to use this for personal interest for locking up the nearest river kilometer if I have an AIS gps position of a vessel. With the patch I can export this data See also this thread: (sorry, with my last post I killed the In-Reply-To:) [gdal-dev] no OBJNAM/NOBJNM after extract distance marks from IENC └─>Re: [gdal-dev] extract wtwdis and unlocd with distance marks from IENC └─> └─> └─> Best Wulf _______________________________________________ gdal-dev mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/gdal-dev
