It is possible to offline edit the map on iPad and upload the edits when connected?

I know nothing about iPads but I can do this with a PC and JOSM. One can download an area and work on it offline for as long as one likes only uploading the data at the end of a session. The only problem is, and it's a serious one, is that if another mapper is also working in the same area and edits an object that you've also edited, a conflict will result. The OSM server doesn't know which version is correct so it prohibits uploading until such conflicts are resolved.

Trust me, you do not want this to happen. Resolving conflicts is tedious and very tricky. In one of my areas of interest, rural Alaska, I can get away with doing this but if you are mapping in an area where others are likely to be working, incremental edits with frequent uploads is highly recommended.

Cheers,

Dave

An alternative to editing offline is recording a track, taking geotagged photos or simply writing down some notes. You can use your GPX track, photos and notes to edit the map when you have access to the Internet again.
