Hi, I have been fascinated by the openstreetmap project, but now I have the following questions: a. working with JOSM vs with Potlatch: I have found working with Potlatch easier. I have been unable to get a Yahoo background to JOSM because where to find wms plugin? The chippy5000 etc... path is never available.
b. when uploading traces with Potlatch, I receive immediate feedback on whether the upload succeeded, and I can see all traces I have uploaded, so it is easy to keep track. I cannot find such functionality in JOSM. But then, if I want to work on those traces in JOSM, when I download from OSM into JOSM, I get no traces. Why? Is that normal? When JOSM uploads, does it upload any traces? c. what happens if I edit an area with JOSM and upload, and before I see anything on the map, I also edit this area in Potlatch? Which set of data will be there? d. for one area that I have added ways to, some of them come from JOSM and some from Potlatch. Does that explain the difference in color? Some ways are darker grey than others. See the area around lat 31.24 and lon 121.56. e. I started to add tags to ways. It is not clear whether I should copy the tag to every way that makes up 1 street, or whether it is enough to add the tag to 1 way. f. I am uploading traces and ways in Shanghai, China. We have residential streets with 2 lanes in each direction and a middle divider. Should I call that a residential street or not? g. I understand that for dual carriageways, the points should be in pairs. I find that difficult to do. I usually put a way in one direction, to ensure all the ways point in the right direction, and then at the end of the trace, I turn back, and put ways in the other direction. Is there an easy process to ensure the points are always in pairs? h. in JOSM, I find it difficult to delete a point or a way. Can someone re-clarify the instructions? (select way, shift-click on point, delete does not seem to delete the way) i. I have a case where 1 street is currently made up of 2 ways, but I cannot seem to join them as per the instructions. I select one way, and then shift-clicking on the other should join, but nothing happens. Any idea why that could be? g. We also have elevated highways on top of normal streets. I understand I should put these on different layers. But do I then put 2 ways on top of each other, with the normal street (layer 0) wider than the elevated highway? How to do that? Any help on these would be appreciated. Best regards, Piet
