Distances

Just saw your Meidum edit and learned that I can use Google maps to measure actual distance. Is that what you did? Doug Weller talk 11:17, 15 January 2022 (UTC)[reply]

Yes, I usually use the desktop version of Google Earth for this. I was surprised that the pyramid was so close to Cairo, I had always thought it was located much further in the desert. Sesquideus (talk) 11:44, 15 January 2022 (UTC)[reply]

Doh, I should have thought of Google Earth. I was thinking that using maps was ok for a short distance, but couldn't see how it would be practical for long distances. I'll remember that. Next question, and I may ask it at RSN, is about citing it. Doug Weller talk 11:54, 15 January 2022 (UTC)[reply]

Prominence and isolation

Greetings, where does the information in this edit come from? Jo-Jo Eumerus (talk) 15:42, 15 September 2024 (UTC)[reply]

Hi, direct measurement via Google Earth. I thought adding a ref like this would just clutter the list. I can add it if necessary. Sesquideus (talk) 15:59, 15 September 2024 (UTC)[reply]

Yes, generally, we want a reference. I am not sure that your own measurement on Google Earth meets the "reliability" criteria, though - for one thing, we'd need an explanation of how the measurement was made. Jo-Jo Eumerus (talk) 16:10, 15 September 2024 (UTC)[reply]

Sure -- but I doubt there will ever be any official reference for topographic isolation (and if, that it would not be obtained by a similar tool anyway). Sesquideus (talk) 16:14, 15 September 2024 (UTC)[reply]

Yeah, probably better to add a reference, and a note explaining how to find the information. Jo-Jo Eumerus (talk) 16:27, 15 September 2024 (UTC)[reply]

I must confess that my understanding is that peakbagger isn't really a WP:RS as noted at Wikipedia:Reliable sources/Noticeboard/Archive 362#Is Peakbagger.com a reliable source? Jo-Jo Eumerus (talk) 11:33, 16 September 2024 (UTC)[reply]

Indeed, I have already found obviously false information there, and yet I cannot find anything better (but I understand that it is computed automatically from SRTM or something similar). Maybe it is best to leave the fields empty then.

On the other hand, at least here in Central Europe even official cartographic sources are often provably wrong when it comes to topographic prominence. Also in the Andes I can see deviations up to ±30 metres in elevation across various sources, even for some relatively major peaks. Sesquideus (talk) 12:03, 16 September 2024 (UTC)[reply]

I'd probably leave them empty, too. I don't think the Central Andes are often measured (governments there have bigger problems, usually, and it's not exactly a mountaineering hot spot) so height/elevation estimates aren't often made. Jo-Jo Eumerus (talk) 14:13, 16 September 2024 (UTC)[reply]

I've hidden the fields for the moment. If better sources can be found, it can be unhidden. Jo-Jo Eumerus (talk) 10:35, 18 September 2024 (UTC)[reply]
