[OSM-talk] GPS scribble in JOSM

[Ed Davies]

When I download some GPS data from OSM into JOSM they
come out as scribble lines.  E.g., here's a screenshot
of tracklogs downloaded around 2006-09-04T12Z for the
Basingstoke area:

I've turned off all of the layers except for the downloaded
GPS tracklogs.  I've zoomed out slightly relative to the
original block downloaded.

Any idea what's going on?

I have a theory/hunch/suspicion: if two tracklogs were
recorded at the same time could it be that OSM or JOSM
is taking the points in time order and therefore jumping
backwards and forwards between the two logs?
