I never did this before but I think http://warper.geothings.net/ may help you to provide a WMS layer that can be used as Background-Layer in JOSM and Potlatch. answered 25 Jul '10, 16:50 MaZderMind I've tried a few of those services, and they're not bad for georeferencing a non-georeferenced image, but won't take the existing information from a GeoTIFF.

If the only thing you wish to trace is a USGS topo, JOSM already had that as an option under the imagery menu pull down. Not sure about other editors. Near as I can tell from the areas I've looked at the scanned topo images are from the most recent USGS versions. answered 15 Aug '13, 15:04 n76 |
