  I picked an area at random near some of his edits:

 Using way id 13292685 : 
http://www.openstreetmap.org/browse/way/13292685 , I looked at the 
edits.  In this case, some nodes were moved, presumably to align with 
the aerial imagery.  I couldn't find any GPS tracks in the immediate 
area to confirm the aerial alignment.   The node I looked at was moved 
at least 10 meters.


  So, the redaction bot will not completely destroy those areas.  If no 
one has touched the road alignment since his work, it will just revert 
back to the original TIGER upload coordinates.  All that is required 
after the redaction bot will be to nudge the nodes to the location where 
they belong.


   A fast preemptive remap for nodes set for redaction-move would be to 
just move the node to align with current Bing aerial.   Note that the 
Bing aerial alignment might not be perfect - try to find some GPS tracks 
in the area to see how close it is.  There should be some tracks on the 
nearest interstate.

[Talk-us] Menlo Park Admin Boundary

[the Old Topo Depot]

It appears that changeset
11339421
deleted
way id 108849539, which was a part of the Menlo Park admin boundary.  As
the changeset is rather large (2,304 nodes; 160 ways) a full revert seems
undesirable.
What might be the best way to recover the deleted way and restore the
associated relation without attempting a full revert ?
Thanks in advance,

John Novak

Download and select relation 1544957 in JOSM, then run the JOSM revert 
plugin and revert selection only. This doesn't undelete the way, but you 
can then download incomplete members of the relation and select the way 
(which now has 0 nodes), then revert again. And done:

(There's also an undelete plugin, but it doesn't always work properly 
for me, especially on a thousand-node way.)

I forgot to mention that you can also use Potlatch 1. Hit U to view 
deleted ways, select the way, and unlock. This is probably the easiest 
for a simple undeletion like this.
