What is the difference between way nodes and current_way nodes table? asked 14 Mar '18, 09:39  _partha |
One Answer:
current_way_nodes describes the links between a currently visible way and its nodes. way_nodes does the same, but for all ways, including older or deleted versions. If you have freshly populated a database with osmosis, both tables will have the same content but if you start editing on your database using the rails port, then the contents will diverge. answered 14 Mar '18, 16:05  Frederik Ramm ♦ |

Far from all nodes in the database are visible and the current* could could be those that are (currently) visible
