Default SSA 2018 - Weather Presentations

Here's a guide covering the basics. It predates the availability of GOES 16 data however and can't really be described as out of the box point-and-click easy. Walt may have a better, more friendly workflow than outlined here.

IDV is extremely powerful but not exactly the most user-friendly. Using it to animate glider flights is something akin to delivering pizza with a skycrane helicopter. On the other hand you aren't just limited to satellite data. Overlays of NWP output (winds, BL depth, etc), new fields calculated from NWP output, and radar data are all possible.

The source data for the animations is publicly available and there are well-documented API's for accessing the data (or for that matter the entire open-source backend for IDV) so adding this functionality to SeeYou is possible in principle. I can't speak to how difficult that would be though.

Of special note is an interesting video:

https://www.dropbox.com/s/vqxvas9nov...Trail.mp4?dl=0

showing 5 minute updated GOES-16 satellite visible imagery 0.5km resolution for a region around Seminole in central Florida. John Mittel's igc flight track is "snail trailed". Using the IDV viewer, there's an overlay of the Seminole landout/TP's (purple '+' with number), airspace and a green box for Seminole itself.

Thanks to John Bird for writing the python script that translates the igc file to the netcdf track format for IDV.



Wow, are there available tools and instructions to make something like this out of any .igc file?

It would make a great online resource too - or maybe the Navier folks would put it on theirSeeYou future features list.
