Is there any tool which can take the differences between two .osm files, and apply those differences to a 3rd .osm file where objects are identified by a tag, rather than by ID i.e. the differences file should contain instructions like "find the node with my_ref=123 and change it's name to x" asked 02 Aug '13, 14:56 OJW |
I fear there is no known tool for that.
All tools I know that are able to convert raw OSM data are the mentiones Osmosis or osmconvert.
Consult the OSM wiki for detailed usage.
