I have thousands of map errors I have collected on my GPS from ground observations. I just have not had time to upload them to OSM. I do not have Internet access all the time.

Downloading many states and then breaking them up using a 'splitter-type' program, gives me the flexibility to edit sections of the country I want to.

I thought UPLOAD conflicts only occur when objects I HAVE MODIFIED, conflict with objects in the OSM database that have been modified since I download MY VERSION. If I have large areas of 'outdated' OSM data, that I do not modify, I should not have any problems when I upload, since I am not sending that 'untouched' data back to OSM, correct?

I thought this was a viable 'offline' solution. I do not know how to filter overpass to download state-by-state regions. GEOFABRIK has already done this, if SPLITTER kept the version dataset information., I could use it.

Will you edit the whole state?
Do you really need to have all of it?

Editing large areas and a lot of objects isn't usually the best thing
to do: it can cause duplicate data in OSM and/or you will hit a lot of
conflicts.

overpass is the easiest way to get fresh data, but you need to filter
a smaller region or some specific data that you want.
