I've just added the Eastoke red bouy as a UGC object.

Can anyone else tell me if they can see it on their UGC layer yet?
 
If its the one at 50 46.687, 0 56.115 then yes, i can see it.

They seem to appear with a green circle with a white cross. I added one at the mouth of Yarmouth harbour about the reconfiguration works.
 
Its also interesting that it appears that one can amend others UGC i.e. I can delete your buoy if I want to. Not quite sure about all of this.

Seems it lets you add it with a resolution of hundreths of a minute then stores it with a res of thousanths of a minute.

Within 12 metres. Close enough I guess.

Feels odd to me too. Something scary about my ability to add objects to your chart.

I guess it's no different to following cairn transits into an anchorage (placed there by god knows who).

At the end of the day I expect people will take this data with a pinch of salt and some might turn it off.

IMHO it's not a great way to the do the job. Crowd sourcing works best when you can see everyones comments. So in Active Captain if 30 apparently capable people say a sand bar has shifted and 2 nutters say it hasn't you can make your own judgement. With Navionics UGC the last one to alter something has the final say. Impossible to attempt to judge the veracity.

Crowd sourcing is great IMHO, but I'm not sure this is the way to do it.

I was originally looking on an iPad. As an experiment I turned my iPhone to airplane mode and then opened Navionics. Your buoy was not there. Turned wifi on, scrolled away from the location, scrolled back and it appeared. Back into airplane mode, scrolled away and back and it was still there.

Seems to be caching?

I've just changed the Red for the Cardinal at Newtown river. I took the correction from Imray here:

http://www.imray.com/corrections/C15_07_6_07.pdf

24 Approaches to Newtown River (Main chart & Plan E)
Substitute W card pillar Lt buoy Q(9)15s for R spher Lt buoy Fl.R.4s in 50°43’·76N 1°24’·91W (ILNW
460/09)


Can someone check I got it right.

I'm really rather uneasy about this... The user now sees two different buoys with red and green x characters indicating the change.

Crowd sourcing is superb, IMHO, but is this the right implementation?

Yes, I can see your change. The problem is that with UGC you can only add content. You cannot change what is there. At some state Navionics will update their chart anyway. Until then there will be two buoys which is confusing.

Rather than put a new bouy in, perhaps it would be better to put some other mark there, or a note.
