Parse the resulting file extracting node IDs, and add lines similar to " lat='0' lon='0' visible='false' />" to the beginning of the file... If you want to/can use JOSM to remove them, when complete, add back the tag at the top, the tag at the bottom and replace all instances of visible='true' with visible='false', load into JOSM and hit upload... Otherwise, you'll probably need to use the bulk import script, for this, you'd add and at the bottom, then feed it through the bulk import script... I hope that helps... It's quite easily scriptable, though perhaps someone has a premade bulk-delete script already... d ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca

When you uploaded those ways you should have gotten the new way_id. If you didn't record this but remember on which day you did the upload you can download the right daily or hourly diff (from http://planet.openstreetmap.org/) and find the IDs in there. (And record the IDs the next time you do a bulk upload for cases like this.) Ok. I found the IDs of the ways I would like to delete. What do I do next to retrieve them and remove them. Thanks.

That is far too long to be able to handle it with current software and makes lots of problems. Are you maybe referring to that? Ways should not have more than 1000 nodes or so. Yes we are. The current ways we are talking about may have more than 40 000 nodes. I would like to delete them and replace them by chopping the ways. Do you known how I could delete the current ones at once. I thought about something like: SELECT boundary FROM ways WHERE (boundary='administrative' AND admin_level=4 AND source='geobase'). The number we should get is 503 ways.
