anybody working on a trajectory plugin?
@stitch thanks, really helpful!
once in a while we have a TS nearby at an event and it is unclear wether we can go for a launch or not; the traj feature helps narrow down the question
@rittels 0.2.0 feedback:
exported trajs now carry over a color - great!
the gpsvisualizer.com Atlas import snag is gone.
here is a traj gpx export example, warped into kml with these gpsvisualiser KML settings :
I think export is just fine now.
Since my birthday's coming up... how hard would it be to play traj's from different models?
stunning: all pressure levels exported, imported with gpsvisualizer to produce KML
have a look in Google Earth!
Brilliant.......you just keep on delivering. 2 model trajectories
@rittels GFS definitely works, ICON - need to re-check, NEMS seems not to work
my last suggestion is already down to usability: append the model name to the export file basename, and each track's name after pressure - then clicking the traj in GE will also report the model, not just pressure; less confusion potential when comparing several model results
Herewith I've run out of suggestions!
GFS, ECMWF and ICON works very well
NEMS, AROME - no output
(IMO not an issue and I dont suggest putting energy into resolution)
@rittels we might have serious test material shortly
I am attending the Sagrantino Cup from July 26 to Aug 4th, and there should be 50+ hot air balloon teams there
there should be 2 flights daily, so that should yield hundreds of tracks in different altitudes
I will prepare and publish trajectories twice daily for each takeoff location and ask the teams to share their GPS tracks with me
@mhaberler Wow, that looks amazing.
I don't know if its possible to include sea currents in trajectories plugin.
It would be very helpful for tracking (lost) floating objects and oil spills
(in case of ship accident).
Of course, I understand that it will be an experimental product
as sea currents data are not updated very often.
... for rubber ducks, also! 😊
Great idea, but don't think the plugin DataLoader contains current data. Possible with the interpolator though. Will try...
Rubber ducks!! 😂
They "pay 100 EUR/duck for the person who find it." 🤣
@Gkikas-LGPZ my ISP career has taught me to stop when done.. which I do here - I am all for single-feature-well-done tools and less so for feature creep
But I guess someone interested in sea currents could take traj as a an example and base to work from
@rittels works fine - all relevant info carried over!
thanks for jumping that many hoops so far!
I just found an interesting feature - incidentally very useful:
do a trajectory for some future point in time and just let the window sit (do not clear)
hit 'Start' again once a new model run becomes available
since the old trajectory is not erased, both (or all) are shown together on one screen - i.e. you can immediately judge how the wind forecast changes over successive model runs
That is super useful for Alps crossings - we need something between 340 deg NW and 10 deg NE to make it across quickly enough and still hit the Po valley
since usually such a crossing is planned days in advance (like 5) the trend in forecast changes is essential even if things looked good initially
nice animations made possible with the traj plugin:
@rittels is doing a superb job on the traj plugin (currently at 0.2.8) - it is progressing very fast
I'm just Joe User here, so let me give you an example where things stand and others can reproduce -
- a balloon ride starting July 11local at my home in Stiwoll, Austria
- simulate all flight levels up to FL180
- simulate with all three available models: ECMWF, ICON-EU and GFS
- do this without simulated ascent/descent
- do this with 3m/s ascent and descent
- save the resulting GPX files (2 sets of 3 files)
- convert those to KML with https://www.gpsvisualizer.com/map_input?form=googleearth
- load the kmz's into Google Earth and screenshot those
all artefacts can be found here: http://static.mah.priv.at/traj/0.2.8/

with 3m/s ascent and descent:
