Is it possible to have real-time live-feed of the entire planet? If cost isn't an issue, would something like that be possible?

In addition to cost, there are various national laws that restrict satellite imagery with resolution better than various thresholds.

How far into the atmosphere does a nation's air space stretch? Would I be breaking a country's law by picturing said country from orbit?

I zoomed into random areas like Chekka, Lebanon and Kumasi, Ghana. I hadn't heard of these places before today, but they looked big enough on Google Maps. Zooming in, the mosaics appeared as if they were shot years apart, with noticeably different resolutions. Could Gaza just be one such scan, rather than something sinister? > "Considering the importance of current events, I see no reason why commercial imagery of th…

The article mentions the Kyl-Bingaman Amendment once around the middle, that's the main reason. The wikipedia article is short and covers it well enough, but in short:

> The Kyl–Bingaman Amendment (KBA) prohibits US authorities from granting a license for collecting or disseminating high resolution satellite imagery of Israel at a higher resolution than is available from other commercial sources, that is, from companies outside of the United States. An exception exists if this is done by a US federal agency, or if it is done in order to abolish the secrecy of such recordings.

Not really related to the article at hand, but I've been on a bit of a Google Maps binge the past couple weeks. I learned a few interesting facts, blurry Israel being one of them. Another strange thing I found that might not be super well known (I didn't know about it) is that all GPS data in China is offset by a nonlinear psuedo-random amount. If you turn on the satellite view in Google Maps and look at various citi…

Recently, I discovered Street View sometimes captures car crashes:

Technical issues apart , there are whole host of privacy issues with that kind of data. Stalking, theft to national security problems.

Imagine if there is real time /continuous feed of your house, it would be very easy to know when you are there and not by just looking for cars parked in the driveway.

Controlling access would be quite challenging.

It's one of the most heavily imaged areas in the world - on the ground, as it's an active conflict zone. In space, satellites will pass over the region every X hours no matter what. Planet's satellites have a fresh, high resolution map of the Earth ~3.5 hours. Google had, at the very least, 7 satellites imaging the Earth in 2017, https://en.wikipedia.org/wiki/SkySat . The question isn't whether the data exists. It do…

> The question isn't whether the data exists. It does.

What is your basis for this claim? However many satellites Google has, why are the regions I named blurry too? Lebanon isn't that far away from Gaza. Cars at Chekka looked like specks. Across the sea, in Cypress, I could make out the front and rear windows of cars.

Nitpicky, but useful for anyone interested in spatial data: WGS-84 is not a "GPS standard" but rather a geographic coordinate system and is usually paired for consumption with a projection like wgs 84 web mercator to view those 3d coordinates on a 2d plane. Super interesting stuff and reconciling these standards across the globe is a really fun problem, and one you'll likely run into if you ever find yourself dabbling in remote sensing pipelines.

The short answer is no. High-resolution imagery comes from low-orbit satellites, which make a complete orbit about every two hours, and image long, narrow strips with each pass, taking days to image the whole planet. There are many of these satellites: commercial, non-military (publicly-accessible) governmental, and governmental (secret), of varying resolutions. These are also supplemented by aerial (plane) imagery.…

Since you know what you're talking about. Say I'm willing to accept the updated-daily or even weekly high-res imagery of the whole planet. Any idea what the cost would boil down to? How many parties are involved? Just wanting to learn more about this.

Sentinel imagery is weekly and is quite good. I use it to see snow melting in the mountains when planning hikes.

Organizations/NGOs heavily rely on satellite imagery (i) to assist in delivering many humanitarian efforts. It would seem useful for the UN to strongly prohibit the diminishing of such capability. (i) www.hotosm.org

Should the UN intend for satellite imagery to be available to NGOs they can fund the creation and distribution of such images, rather than trying to seize the images acquired by a private entity. It’s not that expensive.

That might actually be a really good role for the UN to take - satellite imaging and GPS tracking are security issues for most countries and companies trying to leverage that data have been hit with a lot of regulations and surprises in the past. Niantic had to specifically bow to a lot of concerns about military personnel being trackable through pokemon go when it first came out and private satellite imaging companies need to comply with a long list of deadzones issued by the US Government and other governments across the world.

The bigger question of course is why the "agreement" was made with the Israelis, and not with the Palestinians directly.

Should they have negotiated with the Palestinian Authority, which only partially controls the West Bank, or with Hamas, which took control of Gaza and proceeded to murder leaders from other Palestinian political parties? It is kind of hard to know who the "official" representatives of the Palestinian people actually are due to the failure to establish a functional Palestinian state or government.

> the failure to establish a functional Palestinian state or government.

Wonder whose fault you think it is that the Palestinians who currently live under what HRW and several Israeli human rights organizations consider apartheid, don't have a state.

There’s a company called PlanetLabs (or just Planet) which aspires to this.
