I find it super frustrating to see well funded tech companies boldly abuse open data resources and assume they can just get away with it. I guess that's the theme of 2024. But to make it clear: you are in violation of the license the data is provided under, and as one of the copyright holders I object to that.

Could you please clarify the details? I took extra care to provide all the needed attributions and credits and I believe it is complete and sufficient. If I missed something, please describe it at https://github.com/ClickHouse/adsb.exposed/issues , and I will correct it.

please read the license and its requirements. It is YOUR responsibility to comply with those requirements in order to be allowed to use the data. It is ridiculous that a well funded company asks a volunteer community to tell them how to comply with the license - after they have violated the license and used it for a marketing stunt.

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 have planes without ADSB out.

Sometimes I feel lucky that human's electromagnetic spectrum perception is very limited to the so called "visible spectrum".

Imaging alien species that evolved to perceive a wider electromagnetic spectrum, the earth must look like a disco ball when their spaceship approaches.

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.

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 bombing have transponders off the whole way.)

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.

You can find the attribution and the link to the details at the bottom right corner of the main page. It links to the documentation: https://github.com/ClickHouse/adsb.exposed , which provides the full details. Additionally, you can read the license here: https://github.com/adsblol/globe_history_2023/blob/main/LICE...

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 its individual contributions are CC0.

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 an aggregator, don't condescend on people who do the hard work that you seem to feel free to copy in violation of said license.

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 to the Produced Work aware that Content was obtained from the Database, Derivative Database, or the Database as part of a Collective Database, and that it is available under this License.

I can't read it for you, but I can summarize it for you. You are required to make sure that someone who uses the product (i.e., Clickhouse's marketing stunt thingy) becomes aware of the license and origin of the underlying data. And not by digging into some GitHub repo, but right there, on the page.
