Hi navigators.
The problem is that when I create tracks while travelling, sometimes arbitrary straight lines appear between various track points. They don't seem to affect navigation but are a visual nuisance.
The Ozi people tell me:
"Open the track control. You can use the track list to split the track into sections (removing interconnecting lines). You can also use the buttons on the track control toolbar to make track points active, you can right click on active track points to get a drop-down menu - split track is one of the options".
This sounds pretty cluncky to me as I can't see why users need to take such a step in order to fix what seems to be a software issue??.
Is there a more elegant way to solve this anyone?
Cheers.

John,
This can be caused by loss of signal to your GPS for periods of time.

Agree with Gramps. What GPS are you using? Loss of signal can occur under tree canopy and sometimes in cloudy or overcast conditions. Ozi then attempts to fill in the gaps.

Yep,
Loss of signal is the only way I can think of this problem occuring.
May happen when travelling through trees, canyon, or tunnel, or anywhere else that affects continuous reception between the GPS and satellites.

Thanks all, that's almost certainly it.
I use a G72 and it was breaking up under the karri consuistently last trip. It also has a habit of dropping out occasionaly even in the open if there's too much of a pause between travels.
I have an Etrex H as
well, which would be much more responsive, but haven't yet purchased the cables. It's suddenly become a priority.
Cheers.

I had the same problem.
It only occurred when I used to use a Magellan Map 330 in a cradle. I worked out that the problem was a momentary break in contact with the GPS caused by violent bumps. Without the incoming signal the straight lines took you to the Greenwich meridian or the equator. By adjusting the contacts I solved the problem. I no longer use that kind of GPS.
What sort of GPS are you using?
Bob

John,
Do you have an External Antenna?

Hi Trevor.
No, I am just placing it on the dash adjacent to the window. I'm not sure where I'd connect one to a Garmin72 (the E-trex H wouldn't be a problem as it's much more responsive).
Cheers.

John
Google GPS OZ and buy an external antenna.
and you get less dropouts from the satelites and less straight lines.
You can use the other advice to remove them after the event.
Cheers
Trevor

I found
mine was doing it first thing in the morning when everything was firing up. it was just a matter of scrolling through the points and deleting the first point of the day - not hard to spot they had weird numbers compared to the srrounding ones
