Hi gurglypipe,

I am very sorry if I broke anything or degraded data quality. Yes, I was 
following Bing imagery, after comparing it to Esri imagery and GPS 
traces from the server, and even the old Esri Clarity imagery, all of 
which aligned pretty well.

Feel free to revert my entire changeset if my assumption was wrong. I 
didnt use precision data, so your edit might well have been better.
