[mkgmap-dev] Bridges over tidal water

Thu Aug 30 10:09:26 BST 2012

WanMil,

Thanks for the advice. The pre-compiled sea (replacing generate-sea and 
coastlinefile) has cleared up the flooding I was getting.

As for the bridges - no, there is nothing special about them. The 
relevant tags are "railway=rail, bridge=viaduct, layer=1".

Further investigation seems to show this is a Mapsource draw order 
problem. The bridges come and go at different zoom levels, and sometimes 
one disappears while another on the same screen remains. But all is well 
on my GPSMap 60CSx, so no worries.

Thanks for the help.

Roger
