1. harb Hard to say. Could be a digitization problem. Or a huge wall hook
2. harb2For me clearly sonar ship traces
3. -280 poiOverlay of real photos and digitized terrain model with a bad strip (overlay problem). Press the timeslider, then it will be clear. The pimples in the digital part on the left are funny, I interpret here as a digital error. Whether the water depth is correct there? You can see the real seabed as a foto. At more than 20 meters, he should no longer be visible.
Alright. Browns was a typo. So I do not need a paintbox or UV light.
Now to the Placemarks.
Lock wall 1 --- Probably category artifact. The edge is vector graphics and too sharp for a real object.
LP3 --- The previously discussed sonar traces of ships have usually very different depth values as the computer generated ocean floor. Therefore, they appear more accurate than the model, as "valleys" or "elevations". At the ends and sides of these tracks, wall-like structures often appear.
"Accurate" is relative. There are still resolutions of only 100x100 m per pixel. (The best resolutions are, for example, Hawaii, there are 50x50 m)
P --- Corresponds to your placemark pX.kmz (post of June 27, I have discussed in my post of June 28). Possible further explanation also see below under "Pattern".
P1 --- The end of a sonar track (see LP3), the spikes are the usual guys, nothing special.
Now to the "Pattern" shown yesterday.
What seems like a huge shark's mouth is nothing more than single depth measurement (for example, with echosounder, no side-scan sonar). In a certain grid, the depth has been determined punctiformly south of Guam. And that deviates from the GE model. Now comes the joke: GE takes there both records and superimposed them. The different measurement points areI think because she have used a similar knife driving. now displayed as peaks and we already have this beautiful surrealist seabed that is so not exist. To the east of it looks like a riveted sheet metal. And the data in GE superimposed.
GE gets its seabed data from various sources (SIO, NOAA, US Navy, NGA, GEBCO, etc.). If one now shows two or more records superimposed, happens (I ask for forgiveness) - Bullshit. And with it our underwater anomalies.
KitsuneFox: syzygy - posts I have made here do not receive much attention. I may do a detailed writeup of the now lost Edgemont Park in PA, one of the first electrified trolley parks in the world, but still debating. I'm missing 1 key bit of information.

KitsuneFox: Mount Wycheproof in Australia is the shortest recognized mountain on the world. It stands at 141 feet base to peak. A mineral named 'Wycheproofite' is mined near the location, and is the only known place it's found.

KitsuneFox: Mount Chimborazo in Ecuador is the highest mountain on Earth, as measured from the center of the planet. The peak is over 6,800 feet further away than Mount Everest, and is the closest land on earth to outer space.
