I have a bat file set to run to following command: gpsbabel -i nmea -f %1 -x radius,distance=0.1M,lat=55,lon=-3 -o gpx -F %1.gpx It runs perfectly and the data comes out correctly formatted into the new type. It's definitely that command that's being run. the data is not filtered in the end -- I have adjusted the filter parameters, and it just makes no difference. It's 1.3.6 I'm using. What am I doing wrong here? PS, sorry if this is the wrong place, but i couldn't find a forum, so had to resort to the closest thing. Thingomy |

Without the data, it's hard to say. NMEA files can contain WPL records which we read as points and am rather confident we can filter correctly or simple GGA/RMC records which we read as tracks and are therefore problematic to apply the radius filter to - which is why we document this filter as not working on tracks...

Hi Robert, I replied directly back to John (accidently) a couple of days back as follows: My guess is that you need to convert to waypoints before the radius filter will work (and back to tracks afterwards), this is what I had to do: gpsbabel -i nmea -f in.log -x transform,wpt=trk,del -x radius,distance=0.1K,lat=55,lon=-3,nosort -x transform,trk=wpt,del -o gpx -F out.gpx Hope that helps, Tom On Tue, Dec 30, 2008 at 4:02 PM, Robert Lipe <rob...@gp...> wrote: > > > On Fri, Dec 26, 2008 at 10:08 AM, John Robert Peterson <jr...@gm...> > wrote: >> >> I have a bat file set to run to following command: >> >> gpsbabel -i nmea -f %1 -x radius,distance=0.1M,lat=55,lon=-3 -o gpx -F >> %1.gpx >> >> It runs perfectly and the data comes out correctly formatted into the >> new type.
