How to go about bulk, semi-automated edits

General talk
1

A while back I went through each state in the United States and fixed the formatting of aeroway=runway with numbers that did not have a leading zero. For example 6/24 should be 06/24.

What is an acceptable way to do large scale changes like this in bulk? Should I continue to split changesets in to country or state? Or would it be acceptable to make a very specific change like this to larger portions of the map? For example, all of north america, then all of south america. Or the entire world??? These changes are easy to do in a very automated fashion with a specific Overpass query and a regex find and replace. Not much opportunity for error since it is very specific.

I am using JOSM and Level0 for changes like this. The number of edits like this I have done are pretty limited. So I’d like to hear from others who have done/reviewed large scale edits. Thanks for your input!

Thanks. I have read that before. This is a reminder to just read again. Even if it wasn’t that long ago.

The guidelines must have been why I originally did individual states instead of the whole United States. I also forgot this would fall under the idea of a typo. It appears that these were done by import from a spreadsheet (maybe?) that cut of leading zeros from the front of a string. Now I can start planning. :-)

A general comment: Keep your changeset smaller in terms the area they span. Don’t make them span the whole US.
