another noob needing help extracting gpx data from a DENVER ACG-8050WMK2

[robot797]

Hello
after reading and trying everything from this topic
https://exiftool.org/forum/index.php?topic=10667.0
I still dont have a gpx file
who can help me

[StarGeek]

What is the output of this command, copy/paste it here
exiftool -g1 -a -s -ee -gps* file.mp4

[robot797]

M:\VIDEO>exiftool -g1 -a -s -ee -gps* TEST.MOV
---- QuickTime ----
GPSLog                          : (Binary data 210120 bytes, use -b option to extract)

does that help?

[StarGeek]

I should have also asked what version of exiftool are you using?
exiftool -ver

The version of exiftool you're using can't extract the gps track from that file.  If you're using an older version of exiftool (current version is 12.22), you might try updating to see if the data can be extracted with a newer version.

If that doesn't work, could you make a short sample video?

[robot797]

sorry for my late reply
this is the reaction
M:\VIDEO>exiftool -ver
12.21

I will try and make a short video tomorrow

[StarGeek]

I believe it's best if there's some movement, like to the end of the block.  That way there's variation in the GPS coordinates.

[robot797]

will do
how long of a video do you want?

[StarGeek]

Doesn't need to be too long.  Just some movement that will register different coordinates.  If it's small enough you can attach it to a post here, otherwise you could give a dropbox or google drive link.

Understand, I can't do anything about this.  I'm just trying to make it easier for Phil to take a look at it when he gets the chance.  He may ask you to do something completely different.

If you have privacy concerns, you could wait to see if Phil responds and he'll let you know what to do.

[robot797]

I dont have privacy concerns
so I will make a small video when I am comming back from work

here ya go a video

[StarGeek]

I took a look at it and here's what I saw.

You can extract the data with
exiftool -b -gpslog >file.txt 20210318_095308.MOV

It's mostly text, with an gps location every second.  Each line separated by an FF character (0x0C).

Example of what that log contained

So it looks like it's latitude and longitude.  Though I'm not sure how the location is encoded.  Or if one of those numbers is the time stamp.

[robot797]

mmmmmmm that looks readable
now how would I be able to import it in dashware?

[Phil Harvey]

I haven't yet seen this format of GPSLog.  I'll look into adding support for extracting the GPS from this.

1 is probably the GPS status.  The rest is latitude/longitude.

What is "asl"?  Edit: Ah. Altitude. Right

This will the be accelerometer readings (6 sets of X-Y-Z readings)
