Legend C saved tracks not containing avg speed / elapsed time
|
|
|
| On a recent ride I took my GPS (Legend C v2.5) along with me to record the
track. The active tracklog was reset. When I finished the ride I saved the
track and switched off the GPS.
When I downloaded the track data from the GPS later on into mapsource I
received the saved track and the active track log as you would expect. I
noticed that the active track log contained additional information over the
same saved track? namely average speed, elapsed time, leg time and leg
speed.
I'm sure with my old geko201 this never used to happen and the saved tracks
contained this speed information etc.
Any ideas ? A setting perhaps that I have missed, a bug ?
Cheers N

| This is a known issue. I strongly suggest that you contact Garmin and
let them know that you expect a "save" function to actually save, not
"strip out lots of data and save a small fraction of the original
information which is of very little value".
I think this is a terrible customer disconnect for Garmin.

I believe that this is a design feature not a bug and so Garmin is unlikely
to "fix" it. Saved tracks were designed to be followed using the "Tracback"
feature and the amount of data that is saved is pruned to minimize storage
space. In the same way the data points stored in the Activelog are thinned
out when you save tracks from it.
If you intend to download tracks to your PC then you shouldn't save them
first. Just download the Activelog. The Activelog is fragmented whenever
you turn off the receiver or lose signal lock so that you can easily
separate sections once you have them in your computer.

| David,
Sorry if I seem a little 'bent' about this one, but this really bugs
me. The menu option is "save", and I expect it to do just that, save.
A more accurate menu option (for what it does) would be "Discard the
vast majority of data, strip out all time references, and save what
little useful information is left so that you can use it for
backtracking, but not much else".
Granted, that would be a little verbose of a menu option for the screen
size, but it's a whole lot more accurate than "save", which is not at
all what it does.
By the way, the Garmin web site and manual both say that the option
performs a "save". It doesn't. Not even close. If Garmin were
customer driven, they'd fix it. The least they could do is correctly
describe what it does.

| and the reply i got was
Dear N
Thank you for contacting Garmin Europe.
Please refer to page 35 of your manual.
'The new saved track is a representation of the entire track log from
beginning to end'
The saved track removes 5 out of every 6 track points and only saves some
information.

| My Legend C manual (page 35) is quite different. It says:
"To save a Track Log:
1. With the Tracks Page displayed, highlight the "Save" button and
press ENTER. A message asks "Do You Want To Save the Entire Track?" If
you select "Yes," a "Saving Track" message appears followed by the
Saved Track Page. The new saved track is a representation of the
entire track log from beginning to end."
As we've been through, that's a long shot from what it actually does.
You can download a .PDF of the manual to see for yourself here:

What part of "representation" is confusing you?

I would imagine the parts where the saved track is NOT representative of the
track log (eg time, speed and altitude to name but three)! I'm sure that if
you didn't already know the answer then you wouldn't have a clue what they
meant either. Garmin manuals are just so much rubbish and need to be
supplemented with non-Garmin sources from the Internet (such as Dale's
excellent information) in order to be any use at all beyond the absolute
basics.

Only the time attribute is usually dropped. Neither the Active nor the
Saved logs have any direct speed information although some software
(incl. MapSource) calculates it from the position and time data of the
Active logs. And at least on my current Garmins (eMap, V) both the
Active and Saved logs contain altitude information. My older ones
(III+, 12) didn't have altitude data in any tracklogs.
Certainly there is a loss of accuracy associated with greatly reducing
the number of trackpoints when the log is saved, but calling it a
"representation" seems to cover that.
