I'm working on building a free log viewer to view data from DJI TXT flight logs. My idea is to build a tool that will summarize the flight log and allow all data to be downloaded in CSV format for those who want to do detailed research and/or import the data into another application.

You can upload your DJI GO or Litchi logs here:
www.PhantomHelp.com/LogViewer/Upload


Notes:
  • Uploaded logs might be deleted at some point in the future.
  • Logs are not processed in real-time each time they are loaded. So, you'll need to re-upload them to take advantage of new features I add after you've uploaded a log.
  • This is a work in progress (add your feature requests below).

Change Log:


3/8/18:
  • Now showing individual battery voltages for DJI Mavic flight logs

11/3/16:

  • Added support for DJI Mavic flight logs

10/3/16:

  • Updated to handle TXT flight logs from the current version of DJI GO

3/10/16:

  • Added the following columns to the CSV: RcAileron, RcElevator, RcGyro, RcRudder, RcThrottle

3/9/16:

  • Show white marker on flight path when flight mode changes to/from ATTI
  • Moved non-GPS warnings (e.g. Speed Error) to "Message" column
  • Added the following columns to the CSV: VelocityX, VelocityY, VelocityZ, Pitch, Roll, Yaw
  • Show flight path in green/yellow/red depending on whether there are warnings/errors in the flight log

2/29/16:

  • Added a "Download CSV" link to download a subset of the flight data in CSV format (will be adding more fields)
  • Attached CSV, KML, and flight log files are named the same as the uploaded flight log file.
2/28/16:
  • Added "Speed" column to table
  • Tweaked the data load process to allow page to load faster when viewing larger flight logs
  • Modified table to fill all available space (whatever the map is not using)
  • Removed all but the battery % labels from the points on the map (to reduce visual clutter)
  • Mouse over points on the map to see the label (only works in Google Earth)

2/26/16:

  • Added a Small/Medium/Large setting to resize the map (at the bottom, right of the map)
  • Added a flag icon to the map to show the takeoff point
  • Click the icons on the map's flight path to jump to that location in the table below the map
2/25/16:
  • A Google map will be displayed in place of Google Earth if using Chrome (since it's not compatible with Google Earth)
  • Added support for Litchi flight logs
2/21/16:
  • Added message when home point changes
  • Error-related messages are shown in bold red
  • Added links to download KML & uploaded log files

It's a good start. Thanks and my full support.

There should be an option to see graphical representation of the data. That gives immediately clue to a problem and one should be able to see details around a selected area.

Sorry, I have worked as Director, Product Development so have different approach.

Great start Mike. Thanks.
Healthy Drones shows a battery id which I have used a few times to be sure which battery was used with each flight. Perhaps adding something like that would be helpful to people.

For one-off data (e.g. the battery serial), I plan to show it in an area that gives a summary of the run. Some other things you'll see there are flight time, battery % start/end, lowest battery voltage, top speed, etc.

For example if one sees how cell voltages are varying with time on a chart, one can easily visualize. Reading numbers from a tabular data is ok but it doesn't give immediate impact.

Are you planning to get motor currents too? These plots will be difficult as they will not be steady values.

I do quite a bit of long range flying and thus would appreciate RC signal strength and distance from Home point.

I'm going to add the distance to the table. I don't think the TXT flight log contains the RC signal strength (unless I missed it).

How about coloring the deviations red if > 0.1V like at 8:08 etc?
The data in the table will be color coded. I also plan to color code the lines in the Google Earth map to show areas of low battery voltage (and perhaps other scenarios).

I guess it would be easiest to plot all 4 cell voltage lines on one graph.
Yes that's what we need with a line showing min safe level.

Impressive!
Seems very promising.
Did you eventually crash into that lake or is it just a demo recording? :)
How does one go about viewing the map.( I have installed the Google plugin)
