I think we need some cooperation to fix these complexed situation. How about these steps?
1.define offset value for JOSM and Potlatch <JOSM> offset: 30;-14 ? <Potlatch2> diff(offset?): +0.00026, -0.00003 for example (Bing)43.31880, 38.52070 (Ground)43.31906 , 38.52067 http://www.openstreetmap.org/?lat=38.520231&lon=43.317905&zoom=18&layers=M 2.Re-align featured ways -primary roads -secondary roads -railways -waterways -some huge objects 3.Re-align all objects I think JOSM would be useful to move objects at once.
