When I select a ONC chart which shows bouys etc. online, only the google map shows up in the downloaded kap file. I use OPCN 4.0.0. No bouys, lighthouses TSS etc. are shown. Does anyone has a solution?
files at http://sourceforge.net/projects/opennautical/ are outdated.
http://wiki.openstreetmap.org/wiki/Seamarks#download shows alternatives.
Hope this helps, Dirk
