This is some copyleft troll-level pedantry [0]. They clearly made a good effort to comply with the license. Additionally, ADSB.lol requires contributors to license their contributions under CC0. Databases that don't have some sort of creative work involved in their compilation aren't copyrightable, so it's very dubious that anyone could enforce any sort of restrictive license over ADSB.lol's database as a whole when…

Not at all. It is the polite request to please correctly attribute the data that a company is using for their marketing stunts. I love the fact that techbros being called out for violating other people's intellectual property immediately revert to "TROLL!" or "this is too hard!" instead of actually engaging with the question at hand. And btw - until you actually create the software stack to collect the data and run a…

No one said complying was too hard. This is one of the coolest things anyone's done with your data, they made a good faith effort to comply, and you've done nothing but act like a jerk and project your issues all over this thread. If I ran an ADS-B aggregator that was based on the same software as a half-dozen others, which hadn't seen any significant innovation in years, sitting on tons of data with absolutely amazing potential, I might consider praising the person who just revolutionized the world of ADS-B analysis & visualization, and possibly begging them to help me. And "P.S., could you throw in [specific attribution text]."

It's like writing webgl shaders for ADS-B. In SQL.

Incredible work, and I hope this kicks off a lot of innovation in the world of aircraft traffic analysis & visualization, which I think has been kind of stuck in a rut for a while.

The one glider path over the LAX area is interesting. What was going on there?

I think what you see is CIVIL AIR PATROL and CIVIL AIR PATROL INC

Types: GLID (SGS 2-33A)

Flights: N7589, N2037T

Registration: N7589, N2037T

When you select the dottet square button in the lower left and select a rectangle the planes within this rectangle are listed

Very interesting project!

Oh, thanks. I somehow missed that UI.

The glider I was thinking about is actually N914SF, a Pipistrel Sinus. That's a motorized glider, which makes a lot more sense flying though Class D airspace, right above LAX.

Im surprised to see military traffic over the US. They tend to fly with ADSB out turned off and have an agreement with FAA to be able to do that. Also surprised to see gliders who generally don’t broadcast ADSB out. In the US, we are required to have ADSB out within most controlled airspace and within the mode C veil of a major airport (within 30nm and up to 10,000 MSL). So most GA planes have it but remote areas hav…

Fighters often don't have ADS-B, but there are lots of other military aircraft that routinely use it (transports, etc.). Go to https://globe.adsbexchange.com and press U to show only military.

I'm surprised about this, I thought it's pretty easy to add ADS-B to modern IFF module and they can just switch between different modes.

If you look at https://globe.adsbexchange.com, and filter for military/interesting (the U button at the top of the screen), you'll see that at any given time there are a LOT of military flights over the US. Most are transport, refueling tankers and what seem to be pilots-in-training (mostly in Texas and Florida, some in Colorado), but there are plenty of helicopters and smaller Lear-type jets. When the president or vice president is flying somewhere there are typically one or more E-3 AWACS planes in the air to provide radar coverage.

There are certainly military planes that fly without ADSB, but for flights where secrecy doesn't matter, they seem to fly with it on. I've seen all manner of planes with ADSB, from U2 spy planes, F-15, F-16, A-10, the occasional B-52, and more.

For general transport/rebasing, it seems like it would just make life easier on air traffic controllers, and probably also other traffic in the air (I think TCAS uses ADS-B?). By way of analogy, the military might have permission to drive around at night with their lights off, but it'd make me more comfortable if they did that only when it was operationally useful (i.e. I assume B-2s taking off from Missouri to go bo…

One of the "tells" for military aircraft flying without ADSB is when you see refueling tankers (KC-135) doing loops for periods of time, and no other military aircraft around. Those tankers are refueling something, they don't just fly around for grins.

Is it possible to export a report of traffic by a selected region?

Yes, it is possible to connect to the database directly and run an arbitrary query. Example:

    $ clickhouse-client --user website --host kvzqttvc2n.eu-west-1.aws.clickhouse-staging.com

    clickhouse-cloud :) SELECT t, desc, count() AS c FROM planes_mercator_sample100 GROUP BY ALL ORDER BY c DESC LIMIT 10

Add FORMAT CSV to output in CSV (or any other format).

To obtain an SQL query for a particular region, you can open the browser dev tools (F12), switch to Network, and copy a particular request that is made when you select an area with the rectangle selection tool.

You might be frustrated and that's fine, personally I don't know what's missing either but you simply saying "YPU need to figure it out" isn't helpful at all.

Well, here's the language in the license that apparently is too hard for you to find: 4.3 Notice for using output (Contents). Creating and Using a Produced Work does not require the notice in Section 4.2. However, if you Publicly Use a Produced Work, You must include a notice associated with the Produced Work reasonably calculated to make any Person that uses, views, accesses, interacts with, or is otherwise exposed…

Their banner on the bottom links to adsb.lol and adsbexchange.com, is your specific concern that they don’t have the odbl license called out? I personally didn’t have much trouble figuring out where the data for this project came from based on their banner alone, and thought it was honorable of them to publish their process for obtaining the data.

I have no horse in this race, but am really confused by this aggressive reaction to what I perceive to be a good-faith use of this data. Is this the prelude to some scheme by which you plan to extract money from ClickHouse? The grievance in these replies is genuinely unclear to me.
