Someone may have checked into a bakery on FourSquare at lat=34.716286 &
lon=36.727005. This would then be a location that exists in FourSquare's
DB, but not in the OpenStreetMap base mapping that FourSquare use in their
website. We cannot, for obvious reasons, send people to Syria to map
bakeries, so sources such as FourSquare may be potentially very useful.
How accurate is the coordinate you mention? How does FourSquare get it?
* User puts a marker on a Google map? Then it's not usable.
* User puts a marker on OSM base map? Then the user can do the same in iD
to create the POI
* Coordinate is from a GPS chip in a mobile phone. As we mainly talk about
indoor locations the coordinate is usually off by hundreds of meters. I
would vote not to use it.
One strength of OSM is that data is usually more accurate then other
sources. We should not give away this by importing data from unreliable
sources.
