You are right. loading the whole region into JOSM will probably toast my poor netbook. Maybe I can download the .osm file, split it with mkgmaps splitter tool into managable chunks and load only whats needed. I would then make my edits in a seperate layer (coping nodes and ways from the osm layer if I want to change keys) and then try to merge this into an updated osm layer when I'm back home with the aid of the conflict resolution tool from JOSM. > What is the point > of storing the osm data in a version control system? Well I get the point. You could tell the difference between orignal osm data and updates and changes you made. You could keep track of your changes and even extract just a subset of your changes. So at the end you don't have one massive layer with edits to incorporate into osm, but a set of distinct changes made over time. Of course code repository tools are not made for one large .osm file, so it won't be very comfortable to use. > If I was > desperate I would download a small group of towns/villages before > hand, and then use the update data when I'm online, especially just > before uploading. Well I will accumulate lots of kilometers. So pre-loading just a small area won't work. I need to know what's already mapped and what not. (Not everything mapped in osm is displayed on my garmin).

But my holiday pictures will be taken with a DSLR, which is a bit of overkill for shooting road signs. Additionally I don't want the pictures to mix, so I don't have to sort them out afterwards. I think I can find an old digital 2MP camera which will do the job. (Well they will think I want to open an electronics store when they check my baggage.) regards, Stefan _______________________________________________ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev
