> First, which Projection method to use in JOSM? Mercator? Geographic?

WGS-84 ? (I don't know JOSM's parameter)

>> <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.
>> (Though I'm not good at using JOSM)
