Hi Everyone,

Sanderd17 mentioned in irc that there is a very large data set of gps 
traces now available for all of OSM to use to help us in our mapping.

I hadn't heard of it, but that doesn't mean anything, I never hear of 
anything :)

But on the off chance you are like me and had not heard of it yet, here 
is the info:


I added an image to that page using the strava data in W. Africa and it 
came out very interesting to me.

1. It seems to confirm pretty good image alignment for existing map data.

2. It seems to show roads/paths that we cannot see in the Bing 2012 
imagery. I almost think we could map from this data, but I stress 
almost. But if I was trying to follow a road that the imagery only 
partially showed, and this data was available, I would consult it for sure.

3. Some of those roads we can't see in the imagery go right through 
bodies of water(!?) I do not know if that is a data error or a seasonal 

Anyway, just another much appreciated tool for us to use. Thank you 
again sanderd17.
