[OSM-newbies] Using gpsbabel to filter data - solved !

[Iain Simpson]

As happens - I solved the problem with 10 mts of posting it !.

filter formats only work on specific types of data
Waypoints, Tracks or Routes


Polygons only work with waypoints
not sure why but that's the way it is.
(see http://www.gpsbabel.org/capabilities.html)

as the wiki says

"Gpsbabel lets you filter your results. It can modify tracks, routes and 
waypoints, not all of the filters can handle all three dataforms, check 
with the gpsbabel capabilities page before trying"
