Now that I'm delving into the data from the spark, I wanted to figure out (if possible) how to parse and interpret the data.


I'd like to see the results of my various test flights, particularly what a "normal power up", "normal power down", and the various "landings" look like in the logs.


Does DJI (or anybody else) have instructions on how to parse this data?

Thanks!  Very informative.  It does lack what the user commands (stick) were.  I can see me approaching my obstacle (the house), and backing away from the house repeatedly.  But it doesn't show how I utilized the stick.  I know the DJI GO 4 app will show you that, I was hoping to see it in the flight logs.

I also don't see a power down message.  I was hoping that using the power button to power down the craft was recorded.

in the application under flight record you are able to see the way you controlled the remote

Yep, I know about that one, and I know the various options that I can turn on to see various things (including what I did on the sticks).  I'm now looking for a way to video record the playback of the flight record, or even the phone display of my flight sessions.  I think I found something, trying it now.

Trying to join, it's taking a while to send that verification link.  It looks very promising though.

I read my .dat files from the spark with CSVView. Let's you graph many parameters from the AC.

We would recommend contacting our support via email (support@dji.com) to start a ticket for data analysis if you have any questions at this moment. Thank you for your understanding.

The best I have found is video geotagger.  It is at videogeotagger.com  It parses the txt logs and lets you view your flight along with the captured video on the map.  I believe the pro version lets you see where the camera is pointing at the ground (I am using the free version so I have not played with it, but I know some fire rescue guys who use the camera target feature).

Good to know - thanks for sharing.

Quick follow-up... I started using LineVision software (www.remotegeo.com).  It seems to parse most of the data and it shows where the drone is "looking" on the map.  It works great for fire line mapping.
