Talk:Proposed features/day beacon
i have no knowledge about sea marks, but i don't understand why day_beacon=region_A_red has colour green and day_beacon=region_A_green has colour red. But then what's the difference between region_A and region_B? xylome 2008-06-16 08:34 UTC
- My fault... I'll fix that. Thanks for the catch. --Nickvet419 09:01, 16 June 2008 (UTC)
Maybe specifying the colour and shape of buoys as separate features is better than specifying the type as one attribute. You should consider that IALA is not the only system used. For example, Europe inland waters use SIGNI. Thus, if you want to cover it all in a type attribute, you'll have to add SIGNI and maybe others, I don't know if there are even more systems in use. --Steven te Brinke 07:38, 17 June 2008 (UTC)
- Is there a link to the SIGNI standards? --Nickvet419 07:20, 19 June 2008 (UTC)
Beacon is a fixe construction like a tower, constructed on a rock or rammed in the seaground.
Buoy is a floating construction, anchored on the seaground.
"day beacon" is not a valid expression in international sea-language.

Region A / Region B
Since Region A and Region B is well defined, and have little significance for the rendering of the map, I see no point in tagging the regions different. Most maps will either be Region A only or Region B only, and for those few that crosses the boundry between the regions should either use a region limit to differ the rendering or render it with the same symbol.
The main difference between the regions is that a buoy that would be green in region A is red in region B, the shape difference between the red and green buoys have little significanse for rendering of most maps.
Mark that seperating regions is only valid for floating IALA buoys, all other sea marks have one world-wide system.
Sea marks should be tagged according to IMO definitions, if you are unsure of the correct IMO definition, ask an experienced or proffesional mariner as myself. --Skippern 19:29, 14 October 2008 (UTC)
