[OSM-talk] Half-mapping

Hello all,

Apologies in advance for the following whinge.

Could I ask people to think very, very carefully before half-mapping  
places they've never been and have no knowledge of?

In particular, I'm talking about tracing segments from others' GPX  
tracks. Quite often I take a track for a particular area, and come  
back a while later to map it, only to see that someone has traced  
segments along the line.

This would be super helpful except that:

- The user has done this with no knowledge of the roads. So  
T-junctions have been plotted as corners, and vice versa.
- The quality of drawing is way lower than that which I'd consider  
acceptable. Curves where I'd drop eight points have been done with one  
segment alone. It can be more work to correct these than it would be  
to draw them from fresh.
- Unwayed segments! Gah!

I'm loth to criticise anyone's efforts for OSM - but there are perhaps  
more helpful things to do.

cheers
Richard
