<pre class="moz-quote-pre" wrap="">every tag you add into osm have a changeset with a source tag, isn't it?
so adding the lenght should/must also have a source (extrapolation (sum
of all way of a relation) of osm data is a source)
a few month ago, I have checked the length of Rhône [1]
the french wikipedia list 2 sources for the lenght... both are very fair
away of the lenght found after some work on osm data.
which one to choose? osm without hesitation. maybe it is not fair but at
least it is verifiable (everyone can load the relationship, see the
result and correct errors if necessary) while the other 2 sources
(including the official French source) are totally unverifiable.
unfortunately I did not send in osm the result of the cleaning because
it concerned partly errors in osm (mainly roles in the relationship)
but I started by purging everything that didn't interest me in the
relationship before fixing. it will have to be done again
