[Marble] Re: Nautical information on Marble/OpenStreetMap

[Torsten Rahn]

Yes this is possible using Marble. 

You'd need a texteditor and some understanding of the filesystem to give it a 
try.  There is some manual about creating custom maps, see:

http://techbase.kde.org/Projects/Marble/CustomMaps

Basically one would need to copy/modify the existing openstreetmap.dgml file 
and one would need to add a new layer for the seamarks. As I just found out 
the server Url for the seamark layer seems to be 
http://tiles.openseamap.org/seamark, since at least one of the tiles has the 
Url:

http://tiles.openseamap.org/seamark/15/17485/10492.png

You could even create it so that the seamark layer can be switched on and off 
in the legend. Of course all that requires a bit time and tinkering with the 
.dgml text files. But in general it should be possible with the current 
version of Marble.

I guess looking into the excellent hike and bike map for Marble would provide 
some ideas how to accomplish the task:
