In the past two or so years I’ve been slowly chipping away at consolidating the dry river network other people have mapped on #OpenStreetMap in the #Ajjer region / Tassili n Ajjer (within Algeria).

I think I started with 600 or 800 gaps where the lines of the dry rivers were not connected because they crossed stream pools.

It’s down to 81 gaps now! 🎉

(After this error type, there’s more to be done – but bit by bit it consolidates into connected catchments!)
