I doubt if the sign is unaltered. The typeface and size on “LANDFILL” doesn’t appear to match. Edit: although that might be down to compression. I found a larger version of the image which does look right - even down to the reflective dots on...

Unfortunately there's no simple exclusion operator, at least I didn't find a straightforward solution. It's possible to get a similar result using sets but you have to start from the other end, if that makes sense. First you create a set that...

To be fair, I couldn't be bothered to look for photos, but the silt deposit is asymmetric.

Weirdly, when I first looked at the picture I immediately thought the flow was right to left. Then I overanalysed it and ended up getting it backwards. I was trying to find pictures of fast-flowing rivers to see whether the V should point up or...

I wonder if it might be a Quaker burial ground. There are quite a lot of them in the north of England, and they don't have churches attached. I'm having a look through the Historic England monument list.

Yes, so assuming the photo was taken roughly in the middle of the day (high sun angle, and it was taken this month) then we are looking at a river aligned east-west, with the cemetery on the north bank. The question then is, which way is the...

I had missed this thread. I like a good geolocation challenge. I'm working today (or meant to be) so can't devote a lot of time to it at the moment. The river seems to be quite broad and meandering, so we are not in steep country here although...

Well, Tennessee already has a law regulating cloud seeding. It was passed in 1967 and came into force the following year. The law requires anyone wanting to carry out cloud seeding or other weather modification to apply for a licence, and give...

Can't really argue with the bill. I'd personally support such a bill for the sky above me. But I don't think the bill prohibits airliners producing persistent contrails. I wonder if they've any idea how they're gonna deal with the complaints...

I am always suspicious of "UFO" videos that cut out before the object disappears. Why did they stop filming? Or did they cut the video as it became more obvious that it was just a plane? It certainly looks like a sunlit jet to me, with the wings...

This week Tennessee has moved closer to becoming the first state to actually implement a “chemtrails bill”, although the language is less conspiratorial than some. Tennessee lawmakers have passed a bill banning the release of airborne chemicals...

I always thought most (google) topography maps were made by using photogrammetry techniques.

Looks like this is correct - it's not LIDAR but high-resolution photogrammetry from low-altitude aerial photography. There's a good explainer in this video: Presumably the 3D imagery only gets done once for a given area as it is an intensive...

Whatever system Google Maps/Earth uses to create the 2D and 3D imagery doesn't align very well with moving objects. You get weird things like empty container terminals, trains tens of miles long, and mostly invisible vehicles. Either that or DC...

The vast majority of links posted by that account point to thepeoplesvoice.tv, which is a well-known fake news site (formerly known as NewsPunch). I strongly suspect that the account is affiliated to that site. Regarding the image, I think it is...
