Hi list
see
http://www.unece.org/fileadmin/DAM/trans/doc/finaldocs/sc3/TRANS-SC3-156s2apAe.pdf
for the Inland water S-57 profile, doc from 2001
I have not compared it against the GDAL S57 iw files or checked if there
is a newer version
Hi Even,
Can you submit this as a pull request by editing
done
https://github.com/OSGeo/gdal/pull/2123
So you've added
;wtwdis;unlocd
Is that right ?
yes
Where does this come from ? I can't see that on http://www.s-57.com/ . Or are
they specific to the particular profile of S57 you use ?
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

or an overview at:

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
