I was involved in map business for almost 30 years and I met just a few
people that could have said that in such simple terms!

Thank you

I redid some of my survey yesterday following Pierre and Bernie's 
suggestions. The results are more reasonable. After averaging, some of 
my points were showing error of +/- 2 m or less.

In working on the new trace, I learned to shift the Bing images as 
necessary. Then I found that some buildings fit Bing while neighbours 
did not. I'm getting the feeling that, short of a definitive survey, a 
good map is a matter of careful judgement.

I suspect at this point I should be writing on the Newbies list rather 
than this one. Thanks for your tolerance to this point. Certainly I'll 
still be monitoring this list.
