In reviewing the Wiki for instructions on understanding and debugging relations, I came across this tantalizing snippet ( https://wiki.openstreetmap.org/wiki/JOSM/Advanced_editing#Relations)
"JOSM allows you to sort members, and this is recommended for some types of relations. e.g. route relations, multipolygons, .... Sorting the members allows you to ensure the members are connected, and to locate any unconnected ways. To sort the members click the A-Z button in the relation editor." Great. But what are you actually doing when you "sort the members" of a relation? And after sorting, how does one "ensure the members are connected"? I've noted with dismay the lack of debugging support for relations. For example, I will get an error message when trying to upload an edited relation but when I ask JOSM to Zoom to the error, the display zooms out enough to include the entire relation with no clue as the where the actual problem is. Same thing when you ask to "jump to the next gap". Good luck on that also. Maybe it's just me? Understanding the relation editor is a tough chore. But IMO, a debugging guide would be top priority on my list. Kevin, you have a concise writing style that would probably go a long way in helping elucidate this issue. I fully understand about time constraints (so much to do, so little time) but maybe someday ... Dave PS: As for the "leaves down" argument, my goal is to get named geographic features mapped so the OSM map of Alaska is more complete. I can't afford to be overly concerned about getting the shoreline of a pond or lake perfect. For one thing, it's simply not possible to trace an exact shoreline. The closer you zoom in, the more details there are (fractal geometry comes into play here) and the more nodes you'll need, ad infinitum. Add to that the sheer size of Alaska with its 3,000,000 ponds and lakes and one can get an idea of the enormity of the task. It's simply not practical to be concerned with minutiae like tree lined shores.
