Deleting unwanted tracks

I recently upgraded from a GPSMap 60Cx to a GPSMap 62s. With that upgrade I also had to switch from Mapsource to Base Camp so that my waypoints would transfer from the GPS unit. I have noticed that I now have unwanted connecting tracks between various hikes and cannot seem to get rid of them. Not sure if this is a GPS issue or a Base Camp issue. Let me try to explain...

I went on a hike that comprised of 3 legs. In between the different legs of the hike I turned my GPSMap 62s off while driving to the next hiking location. Upon arrival at the next hiking location I turned the GPS unit back on. I repeated this cycle for the 3rd hiking location. When I viewed my tracks in Base Camp there were "as the crow flies" tracks that connected each leg of hikes. Obviously I do not want to see that. I tried using the tool in Base Camp to delete the connecting end points, but all that does is make the unwanted track jump down to the next available point and attach itself there. So that did not seem to work for me. I then tried to use the Divide tool and while I had trouble even getting it to do anything - at best all I could get that to do was to turn the unwanted connecting track from a bold, bright track to a dimmer, skinnier track. My goal is to not have these interpolated phantom tracks in the first place.
Does this appear to be a "feature" of the GPS 62s or of Base Camp?

    Your GPS should have a way to turn off Tracking. I know it's a pita. I have an Oregon 450 and i have the same problem. BaseCamp does let you remove sections. Click on the Track you want to edit using the Select Arrow. Then the icons on the toolbar for track editing will be enabled. Locate the section you want to remove, and use the Divide to separate it. Now you can use a number of ways---the one i prefer is to Move Point and move it away from the rest of the track, repeat it for the other end and then Erase or Delete the segment. If you are lucky, when you mark the long, straight segment with the Divide button, you can just delete it from there.

    As with most things we edit--save your original track first, and then after segments are deleted, save again. If you screw up--it's easy to go back to the last version.

    You just need to play with it to get comfortable.

    Folks have mentioned on the Wikispaces Garmin about the need to easily turn Tracking on and off, without going 3 or 4 menu levels deep to turn it on and off.

    Again i'm referring to my O450. While hiking--you could also Save Current Track when you are done with a hike. this will give it a unique name. Then Clear Current Track when you are beginning your next hike--then you will not have the "as the crow flies" segment--it will be cleared. This is the easiest way if you remember--but if you forget--then you gotta edit.

  • Thanks for the information Ron. I was able to remove the unwanted tracks, but it is kind of cumbersome. I had to select the track, then click on it using the Divide tool. Clicking on it with the Divide tool doesn't do anything intuitively obvious. I then had to zoom in close enough such that I could click on the point associated with the endpoint of the unwanted track so that the info bubble would pop up and I could identify which point it was. Then I would look in the tabular data listing below the map and manually delete that path. The HELP in Base Camp does not go beyond clicking the track with the Divide tool. After that you are on your own as to how to complete the operation.

    This auto-generated "connect the dots" track is a feature of the GPSMap 62s apparently. It does not do this with the GPSMap 60Cx. I would hope that in a future software update Garmin will at a minimum make this "feature" an option in track logging preferences. This is a nuisance feature to me.

    While I am here... am I missing something? Is there no forum for the actual GPS units?

    The closest forum for you units is http://garminoregon.wikispaces.com/ I have seen posts there from Garmin folks. This general forum above has Cycling and Running GPS forums, but no Oregon nor 60's.

    Does your GPS have provision to Save Current Track and Clear Current Track? If so, as i mentioned, after every Hike, Save your Current Track, and prior to beginning your next hike, Clear Current Track. This procedure should keep you from getting these "as the crow flies" extra tracks. I think you want to keep each hike separate anyway.

    But those should be easier to remove then you describe. There may be some extra cleanup--if you a perfect map. The ones which are harder for me to remove are when somehow in BaseCamp the Start and Stop of a track get connected together.

  • I have tried two methods to no avail.

    The first method was to turn off tracking at the end of a segment, power down the unit, walk to a new location, power up the unit, start the tracking again, walk the next segment.

    The second method was to save the current track at the end of a segment, power down the unit, walk to a new location, power up the unit, walk the next segment.

    In both cases when I view the tracks in Base Camp the segments are joined together as if it were one continuous track. If this is the way the GPSMap 62s is supposed to work then that is a real disappointment.

    I think you missed a step in the 2nd method. At least with my O450, I NEED to Clear Current Track, BEFORE i start the 2nd hike. Otherwise the TrkPt from where i turned the GPS off at the end of the 1st hike is still in the GPS.

    Maybe your GPS deletes the Current Track when you power down--i don't know.

  • You are correct Ron. I forgot to mention that, but yes I did clear the current track after saving. As soon as you save a track in the 62s it asks if you want to clear the current track and I chose yes. I then powered it off, walked to a new location, powered it back on, and it started recording a new track (the previous saved track not showing on the screen). I then walked the new section and then saved that track. When I display both tracks in Base Camp the two segments are still connected together. As far as it looks right now the only way to overcome this is manual editing in Base Camp which we already know is not as intuitive and user-friendly as it should be.

    NO NO---- BEFORE you start your 2nd hike (vs at the end of the 1st Hike), Clear Current Track. Don't bother to clear it after you Save Current Track at the end of the 1st hike.

    You can't press Clear Current Track after you save your 1st track, and power down fast enough before it records the TrkPnts you are at. So to get around that-- before you start your 2nd hike, Clear Current Track, and then Enable the track recording. When you do it in this order--there is no connection between the 2 tracks. In fact before you ever record a new track, you should always clear current track just to make sure that buffer is empty. Does that make sense??

    This will create 2 separate, unconnected tracks. So when you open BC, you will see separate tracks.

    It's much easier to keep from recording the extra points, than trying to remove them after the fact, altho you can--it's a pita.

  • Thanks for your patience Ron. Yes - that makes perfect sense. So much so that I am surprised that did not occur to me. I always cleared tracks and reset data right before my first hikes when I used a GPSMap 60Cx for that very reason and the light bulb still did not come on for me in this case!

    I tried a couple of segments around my house clearing the tracks at the beginning of the 2nd leg and it works perfectly now. Many thanks. Still a PITA, but like you say much easier than editing after the fact.
