[OSM-talk] Proposed bot edit: remove "surface=no data" and other useless surface values

[Imre Samu]

> I propose to remove following surface tags by doing an automated edit:

some comments:

1.)  Root case analysis
It would be nice to have a 2-3 month grace period,
meaning that those who want to analyse the data in more depth can do so,
( tag combinations, distinct users, years, osm editors, etc.. )

2.)  count_tags()==1 and surface=*
Sometimes there is only one surface tag on the geometry.
In this case, removing just the last tag  -  will not fix the problem.
What is your proposal in this case?  ( keep or drop the geometry? )

3.) count_tags()==2 and surface=*  and name=*
To a local editor, I think the two tags together give more information than
only the name=* tag
This means that half-corrected data can be more human work later.
( not always of course )

3.) Transparency:
It would be nice if there were some kind of continuous data collection
(statistics) on corrections.
Some kind of simple dashboard about the automated edit.

Anyway, the problem is real, and some solution is needed.  :-)

best,
 Imre
