[OSM-talk] Stupid Josm question

[Barnett, Phillip]

I'm an idiot. That's exactly what I was doing wrong. Thanks - that works
great.

When you load in the gpx file to JOSM, hit the "No" response to "Do you
want to open as raw data" and you will find all your trackpoints turned
into nodes and each separate continuous log turned into a way. 

Not advisable to use this method in areas where there is already a lot
of data.

Cheers,

Andy
