I draw some coastlines, how can I add polygons that use the same nodes as the coastline. E.g. The rather complex coastline is made up of cliffs so I want to add and area with "natural=cliff" along it, but I don't want to click every node in that coastline one more time.
This is the same if I want to tag landuse=forest, and then have a joining landuse=farm. |
complex coastline (blue) + other area (red) that should use the blue line too

JOSM now has a follow line tool similar to that of Potlatch that allows to easily create a new way along an already existing way. |

I found JOSM plugin contour merge it seems to do it, does it work?

In Potlach2 start by making some nodes and when you get to an existing line you wish to follow do a couple of nodes along it then press f (for follow) (see my question Potlach2 using natural boundaries for tagged areas) Very easy to use, this works great!

In JOSM, you can achieve that with some tricks:
It's a little bit tricky, but I haven't found another way to properly duplicate the wanted path. |

You shouldn't be making overlapping ways, use a multipolygons instead. Draw each boundary line once then add it as an outer way in a landuse multipolygon. emj, http://www.openstreetmap.org/browse/relation/392840 and http://www.openstreetmap.org/browse/relation/392841 may give you some hints. Also specifically read http://wiki.openstreetmap.org/wiki/Relation:multipolygon#Tagging from the link Alchemy already gave you. For example: "It is suggested to apply all tags which describe the area to the relation, and not to the ways. In many cases this may result in completely untagged ways." (BTW: The parking area nearby isn't pretty done, but the examples above still should give you the idea how to reuse already existing ways.)
