[Tagging] Waterway length

[Sergio Manzi]

TBH, I'm all with you (/and maybe I'm seen as an eccentric too.../) and I see the tagging of waterways length as egregiously useless.

Beside, I smell a lack of verifiability [1] in this waterways property: I'm not a geographer, by far, but in the years I made up my mind that this is one of those things that experts debate in their congresses and can be object of accademic thesis.

On the other hand a tool to compute the total length of waterways from their source (/once you have pinpointed it/) to their mouth (/again, once you have pinpointed it/), could be really interesting.

A static value for a river length in OSM, without any information about its source (/pun not intended, but valid anyway.../), is the kind of information I will usually route to /dev/null and for which I'll seek more autortiative sources (/again.../)
