Dear fellow mappers,
This day I encountered a river while drawing a path.
As you can see, some one else drew a track up to the river.
I understand that for routing purposes, the two ought to be connected. My question: is there a way to indicate the river as a barrier in the track/path?

Connect up the two paths and the river, tag the connection as a ford?

Do you know that it is a ford without trying it out?

I think you have to accept there are some limitations on satellite mapping
and make a best guess or judgement call. If I can wade across it in the
dry season and it comes up to my chin is it a ford?

Mapping in the UK is different, more mappers on the ground for a start. A
lot of African mapping is done for HOT and the aid agencies and often the
alternative is nothing at all. There just isn't enough people on the
ground with good internet connections and a knowledge of mapping to do the
job and I'd prefer not to get into a discussion on how OSM should only be
done by people on the ground.

Thank you all for your replies. I appreciate your help as this issue got resolved fairly quickly. Now I can finally commit the changes and mark the territory as done.
Thank you once again!

True. Labeling it as a ford implies that it can safely be crossed on foot
or in a land vehicle. It may require the use of a boat or raft to cross
safely, due to water depth, strong currents, a quicksand or mud bottom, etc.
