[Talk-gb-westmidlands] Personal Survey Points

[Big Fat Frog]

Hi all,

Been it this for a few months now, got a Garmin Etrex Hcx, quite pleased 
with it's accuracy but am wondering how best to add my personal survey 
points to OSM.  When I come across a land feature or man-made feature 
that is visible from sat imagery that is very distinct, such as the 
corner of a wall, I like to take an averaged waymark, with as many 
points as I have time for, I can usually get the approx accuract down to 
less than a metre.  How should I tag such waymarks on OSM?

Cheers

Jonathan
