XC scoring in Leonardo
Having spent all day trying to upload some recent flights into Leonardo I've become stumped as to why the Max distance, XC distance and XC score aren't automatically calculating.
Can anyone with a bit more experience uploading flights shed some light on this problem?
The flights in question can be found by searching under my name, Graham Surrey.
Cheers.
Spent all day - don't you just hate that!
Hi Graham
Don't know why but I could not find you by doing a pilot search in Leonardo.
Assuming you can see them displayed in Leonardo.
Give us some more info such as country, date, site - that may pinpoint your flights.
Or if you like email me one of your IGC files so I can have a go at loading one into Leonardo.
My email is 2ftagl@gmail.com

No timestamps
I have had a look at your IGC files and noticed that there are no timestamps on your track points. I'm guessing that you use a Garmin and that you chose to save you tracks in the Garmin before you downloaded them.
Garmins (at least the 60 series) very kindly remove all the timestamps for you when you save a track. The trick is to NOT save your track, just turn off your Garmin at the end of the flight. All your track points are kept and you can still download your tracks to a PC. All the track points will be concatenated together but you will find that the first point recorded each time you turn it on will be flagged as a "START" record so you can still distinguish each individual track.
Oh crap!
Thanks Wayne & Tony.
Wayne, you're quite right. I've got a Garmin 76C and I saved each track after I landed, since that would seem to be the logical thing to do! I was wondering why there were no timestamps, so your explanation makes sense.
In terms of fixing it would I need to go back and manually enter times next to each track point in the IGC file?
One of the other guys on the Bright trip was using a Garmin 60 series GPS and his tracklogs are displaying fine in Leonardo, so I was stumped as to what the difference with mine was.
On a related point, I set my GPS to take a position every 30 seconds but for the flight on 15 March, for example, it has only 367 track points even though it was a 3hr 30min flight (should be at least 420 points). The tracklog as it stands appears to accurately show the flight but I was just wondering where the extra data points will have disappeared from.
Also I've noticed that when turning my GPS back on it has the charming habit of drawing a straight line on the tracklog from the previous point at which I'd used it. This meant that when downloading the tracklogs to my laptop I found that there was a 2300km track stretching from the Paeroas to Bright. I'm thinking that the answer to this is to turn the tracking function off between flights maybe?
Sorry for bombarding you guys with questions, but after spending almost all of Sunday having to wrestle with deleting erroneous track points and figuring out how to convert MapSource files into IGC format I'd pretty much reached the end of my patience with the damn technology!
It's the first time I'd used my GPS to record any XC flying and I'd really like to be able to display the data properly so I can go over it again. Any help is appreciated!
Cheers,
Graham.
Timestamps
Manually entering the timestamps could fix the problem but it would be extremely tedious. I don't think you would be able to do a mass search and replace because each timestamp would need to be different, otherwise you will have infinite speed between points, and Leonardo may not like that.
I don't know why you are missing points. The only reason I can think of is if you have it switched on to automatic mode, but it sounds like it is definitely on 30s instead. I usually fly with mine on automatic that way it drops points if you are flying in a straight line but keeps more points when you are turning. So you get the minimum number of points but still get good detail where you need it.
I use GPSDump to download the tracks. I scroll through the track log looking for the points marked with "START" or looking at the timestamps. Then select the track points for the one flight I am interested in, ie from one START record to just before the next START record. Then save that flight and upload to Leonardo.
Hope that helps

Graham
I have a Garmin 60, and yes I don't switch logging on until just before launching, and on landing I switch it off. I never use the save feature for the reasons Wayne has mentioned. (Been there, done that)
I have the data record interval set to 5 seconds. When I first got my GPS I calculated from the specs - it can store 10,000 tracklog points, one every 5 secs would last 50,000 seconds, or 833 minutes, or +13 hours - more than enough time to fly 250km (yeah right). Even with 4 to 5 hours of logged flights it has never got close to filling the log. So I reckon the smaller time interval the better. A lot can happen in 5 seconds.
See you on the hill

Tracklogs
If you have your Garmin setup to save tracklogs to memory card (quite likely) then you will be able to retrieve your tracks from there. Switch your GPS into USB mode when it is attached to the computer and you will see a file for each date. These are complete GPX logs from that day (and are compatible with IGC). Open them in MapSource to play around.
In fact, if you have a decent SD card in there (2GB+) then you could easily switch to 1 sec tracklogs and have room for several years of logs. 1 sec tracklogs isn't for everyone but it does give you beautiful curves on the map.
Good news
Thanks for all the advice guys.
Fortunately I managed to retrieve my tracklogs with timestamps and other data attached by just downloading them using GpsDump. The saved tracks were still there with their timestamps removed but by scrolling down further I found the unaltered tracklogs, which was a relief. I've now uploaded them into Leonardo and they're displaying fine.
This discussion was useful though, as I'm not going to mess around with saving tracks on the GPS unit in future.
Getting finer resolution on the data by setting up the GPS to record points at much closer intervals is a really good idea, as 30 second intervals do give a somewhat coarse representation of the flight.
It was a bit of a learning experience but at least I've now got a much better idea on how to properly use my GPS. I'm sure I won't be the last person to get frustrated with their Garmin either, so these pointers could come in handy for someone else.
