    Hi Maning,<br>
    <br>
    If I remember correctly, Bing imagery had a slight offset relative
    to the streets that were present before yesterday. So it is likely
    that Bing offset should be adjusted, maybe relative to a coherent
    set of "older" streets in the center, assuming that maybe a local
    mapper had been able to have them better referenced, maybe using GPS
    traces that were not uploaded. (These are many "maybes", and just a
    quick guess without having looked closely at the data. Anyway, it
    should be in OSM "best practices" to start with adjusting the
    imagery offset to existing data, before tracing from it - unless one
    has a good reason to think that the existing OSM data itself was
    offset).<br>
    <br>
    <br>
    Many thanks to all those who helped and are still helping. I see
    that building are also starting to appear. You are awesome!<br>
    <br>
    Best,<br>
    <br>
