Hi Matthew,
I made an unofficial snapshot a couple weeks ago that ended up on two ATC
flight simulators (ATC is the company name, not the function) at a school on
Long Island. It's not too hard to make a source snapshot if I don't worry
too much about release notes, change logs, binary builds, etc. I've been
wanting to move towards some sort of regular developer snapshots, but I've
had too many things on my plate.
I have a coworker in town this week to do UAS flight testing so I'll be tied
up with that most of this week. But if you ping me later in the week I
would have more time to think about this.
BTW, just to wander off topic here ... I added a simple extension to the way
point system on our UAS so that waypoints can optionally be specified as an
offset heading and offset distance (rather than a fixed lon/lat.) The
ground station can send up a new reference point periodically and the UAS
will compute a new route relative to the new reference location. And then
the UAS will trickle the new points back down the ground station so you can
see the updated route on the map. We have an application (debris/junk
survey) where NOAA wants to fly a survey pattern out in front of a moving
ship ... static routes don't always work well out there ... especially if
the ship has drifted a mile or two between when you program in a route and
when you get clearance to launch. It's need to click on the map and say
"move the reference location here" and watch the route adjust itself.
BTW, really neat stuff with the 8 monitor demo! If I had to nitpick, I'd
suggest that (at least from the video) it appeared that not every display
was identical in size? Also, with Tim's most recent CVS changes, it's
possible to adjust the view parameters for each monitor to account for the
gap between monitors (i.e. so it doesn't look like you sliced up an image
into 8 pieces and then spread them apart.) And if I was getting really
nitpicky, I suggest that it might be fun to go blasting up some valleys in
the mountains east of seattle somewhere, although flying around SFO isn't a
bad choice either ... perhaps some dusk/dawn flying would have been fun too
... (But I do realize there is only so much you can show in a couple minute
demo.)
Regards,
Curt.
