[Talk-gb-westmidlands] Personal Survey Points

[Big Fat Frog]

Thanks Gregory and Andy for your feedback.  You're right, next day I got 
a different result but only about 2 or 3 metres out.

I long been convinced that the arial imagery is out and I've read as 
such elsewhere but if I use an offset then my changes are at odds with 
the the bulk of what others have done.

So which is the yardstick?  Imagery, accurate survey points or something 
else? Also, if you beleive you have a hyper accurate surevy point, then 
shouldn't that be uploaded to OSM?

Hope to meet some of you at Maptitude next week!
