Strikingly beautiful! It's hard to get a sense of the scale of the scene, anyone happen to know how far away the webcam is from the peak?

Strikingly beautiful!
It's hard to get a sense of the scale of the scene, anyone happen to know how far away the webcam is from the peak?
- Tepix 6y agoI see a few rocks in the foreground and a lot of fog. Fagradalsfjall is nowhere in sight as of 08:34 UTC. Edit: Now 20 minutes later the white smoke is gone. Stunning!
- input_sh 6y agoAshes and sunlight are obstructing the current view, if you go a little back in the stream, you'll see what's happening.
- granra 6y agoNot too far I think. This eruption is apparently competing with one other eruption on being the smallest eruption on record in Iceland. Source: am Icelandic and read it on the news.
- asgeir 6y agoLooks to be about half a kilometer. The webcam looks to be at about 63.89045405043735, -22.279054215941507 and the main crater is at about 63.88921695342744, -22.269097856211175 The main crater is only a few tens of meters tall.
- jstanley 6y agoAbout?! The 14th decimal place of latitude is worth ~0.15mm!
- adwn 6y agoAlthough that might have been tongue-in-cheek, the word "about" could refer to the accuracy of the position, not its precision. Precision != accuracy: https://en.wikipedia.org/wiki/Accuracy_and_precision https://en.wikipedia.org/wiki/Accuracy_and_precision
- elcomet 6y agoBut the number of digits should reflect the precision.
- unhammer 6y agoWhen pointing at a map, the thickness of your digits should reflect precision.
- airhead969 6y agoHow accurate are your digits?
- airhead969 6y agoYes. If it's only 5 digits, it should be cut-off to reflect that. Accuracy needs an error estimate.
- Moru 6y agoIt's hard if you don't know the precision needed to get to the position you want, easier to just copy/paste and be done with it. How many knows how far 0.001 deg is at a specific location on the globe?
- asgeir 6y agoI find it hard to estimate the position from the top-down view compared to when I was there, and I just copy-pasted the coordinates from Google Maps
- airhead969 6y agoThe smallest possible resolution of GPS in the horizontal is 10mm (6-7 digits) with local differential corrections. In general, 4-5 digits is the precision to expect.
- jstanley 6y agoHm, then I think my calculation that the 14th digit is worth 0.15mm must be wildly incorrect. For a 40km earth circumference, I worked out 10^-14 * 360 * 4*10^7 = 0.00014 metres.
- schoen 6y agoI think you want to divide by 360 instead of multiplying by 360 - when you divide by 360, you should get the linear distance represented by one degree of latitude or longitude.
- hr2016 6y agoThe camera is located on Fagradalsfjall and the eruption is in Geldingadalir. The exact location of the camera I do not know, but its somewhere in the ~1km range.
- Tepix 6y agoFagradalsfjall is only 385m high.
