I haven't worked on any of the lower squares yet, but I have found
that there are several gps traces. <br>
<br>
It's worth checking for gps traces, and if you get one of more,
align the roads to the trace(s), then align the imagery to the
trace. I'm tagging roads that have a gps trace as<br>
source=gps;Bing for their length which matches a gps trace.<br>
<br>

problem arizes with the first two bottom rows in the left

approx. 30 meters between th two Bing images that overlap.
You will see the more detailed image if you zoom in closely
(under 40 meters with JOSM), <br>

style="" class="">In such situations,if a village is offset
30 meters with the rest of the world, this is not a great
problem. But inside the village, we want to respect the
overall geometry, the alignment between individual buildings
and roads. If a previous mapper used the less detailed
imagery, I suggest that you simply do the same and just
complete adding objects not already traced.<br>
