What is a "country"?[edit]

I dispute many of the table entries, as they are not "countries". For example, French Guiana, Martinque, Guadeloupe and Réunion are integral parts of the French republic; calling them "countries" is akin to calling Alaska and Hawaii countries (and neither of those appear on this list). Similarly, Svalvard and Jan Mayen are integral parts of the Kingdom of Norway, and not classified as territorial possessions. I know that ISO 3166 has unique codes for these places, but that does not make them "countries". This list ought to align with the identical inclusion criteria as the main list of countries we have on this wiki. — Andrwsc (talk · contribs) 17:21, 11 September 2009 (UTC)

  • Excluding Greenland would mean Denmark, for example, would need to reflect Greenland's figure. So not useful. Denmark does consider Greenland to be a separate country so that is reason to keep Greenland. Nice to have Antarctica in the list too. Could the lead description allow for significant geographic areas too?--Andynct (talk) 21:13, 17 May 2015 (UTC)
The list of countries seems to be based on ISO 3166-1, which is an official standard.--BIL (talk) 20:26, 3 April 2016 (UTC)
ISO 3166-1 Looks like a good definition. Thanks. Any objections to using that?
Perhaps those areas which are not sovereign states or disputed territories etc. (Greenland, France Territories etc.) could be italicised? This is what I've seen on other lists like this. LaiYeh (talk) 09:16, 13 May 2016 (UTC)

Har Meron[edit]

Har Meron is the highest elevation in Israel, Hermon is completely within Syria and Lebanon. --Supreme Deliciousness (talk) 18:48, 1 September 2010 (UTC)

Serbia and Kosovo[edit]

Gjeravica/Deravica is posted as the highest point of both Serbia AND Kosovo, because recognition of Kosovo is still disputed. Fine. Although I think a note at the "Serbia" entry should tell the interested Wikipedians, that the highest point of Serbia proper ist the Midžor: 2,169 m >> see it at the CIA World Factbook Beraldosuperfigo (talk) 19:24, 20 September 2010 (UTC)

Disambiguations[edit]

In See Also, the link to summit should be to Summit (topography). I can't do it since I'm new here, so could somebody fix that up? Thanks. CarnivorousGnomeCatuse (talk) 19:43, 25 December 2011 (UTC)

Done. But I thought that was a change anybody could make--even an IP (that is, not registered) user. Uporządnicki (talk) 18:17, 16 June 2012 (UTC)

Merging With Elevation Extremes[edit]

'Strong Support of Merge'- There's a page already that contains high and low points for countries. Having a high points and a low points page in addition is superfluous. Let's do a merge Cesium 133 (talk) 08:43, 24 October 2014 (UTC)

It's been more than 5 months since the merge was proposed, and no one has objected to it. I'm going to perform the merge. There is really no need to have three articles for something that can be comprehensively covered in one. Vanjagenije (talk) 10:35, 6 April 2015 (UTC)
It's just an opinion, but I'd prefer to revert this merge because the former List of countries by highest point had an elevation ranking, while this article doesn't have it. That ranking was an important information. Scheridon (talk) 22:09, 19 August 2016 (UTC)
Feel free to add it to this article. No need for whole new article just because of that ranking. Vanjagenije (talk) 19:42, 21 August 2016 (UTC)
I think a ranking is not possible to this article because of its format. The previous format was better than the current one. Scheridon (talk) 22:25, 1 September 2016 (UTC)
Why exactly do you think it's not possible? I think it is possible. Vanjagenije (talk) 16:15, 2 September 2016 (UTC)
It's not possible because the countries are disposed in an alphabetical order (not in an elevation order). Scheridon (talk) 15:25, 3 September 2016 (UTC)
@Scheridon: Yes, but this wikitable is WP:sortable. It can be sorted by any column values. That means that you can add a column with ranking and the table can be sorted by that ranking with just one click. Vanjagenije (talk) 17:10, 3 September 2016 (UTC)
@Vanjagenije: I hadn't thought about it until I read your comment (lol). What a shame! Scheridon (talk) 02:29, 4 September 2016 (UTC)

Greece[edit]

An area in the Evrotas Municipality in Laconia,Greece has an altitude of -3 metres just immediately north of the settlement Trinisa according to Google EarthWeatherextremes (talk) 19:09, 1 September 2016 (UTC)

Actually the lowest point of Greece is in Missolonghi with -6 metres .Have now corrected this on the articleWeatherextremes (talk) 02:14, 2 September 2016 (UTC)

Well it seems that after all the lowest point of Greece is in Aetolia-Acarnania at -7.98 meters. Weatherextremes (talk) 07:28, 2 September 2016 (UTC)

yet another change in Greece's lowest point.I reckon this time is the correct one Weatherextremes (talk) 00:22, 3 September 2016 (UTC)

@Weatherextremes: You should provide some WP:reliable source. Vanjagenije (talk) 14:23, 3 September 2016 (UTC)

The source is in the Aetolia-Acarnania article and is reliable.Check it out [1] Weatherextremes (talk) 18:40, 3 September 2016 (UTC)

@Weatherextremes: You need a reliable source that says that particular point is the lowest point of Greece. That source doesn't say that. WP:Original synthesis is not allowed. Vanjagenije (talk) 19:00, 3 September 2016 (UTC)

Well then there is a problem of consistency with the article because at least for Europe most of the articles per country do not specifically say this.In fact for Netherlands you get a pretty generic statement that the lowest altitude is somewhere between -1 to -7 meters.I have been checking all over Greece the past few days and this is the lowest altitude I could find.I devoted close to 3 days for this so I am pretty sure this is the lowest altitude that can be found in Greece Weatherextremes (talk) 19:13, 3 September 2016 (UTC)

Ok i noticed that for Netherlands the CIA fact book is the reference.But what about France?I couldnt find any reliable source that states what the lowest altitude is.In fact i think this is the case for other European countries as well from what I remember when I was checking the past few days Weatherextremes (talk) 19:34, 3 September 2016 (UTC)

Germany as well.The article Neuendorf-Sachsenbande does not seem to have a citation Weatherextremes (talk) 19:47, 3 September 2016 (UTC)


@Weatherextremes: In regards to finding the lowest point in Greece, unfortunately it is not enough to go to Google Earth and find the lowest altitude listed there Wikipedia requires someone reliable to have actually published where and what the lowest point is, you trolling Google Earth for the lowest point is not acceptable and is WP:Original synthesis. Google Earth is great but is simply not accurate enough for you to accurately derive the figure you have from it. I have looked and I agree that the area is probably at least partially below sea level (probably maintained artificially so, however I'm not sure that matters) but it is unlikely to be 10 metres below, particularly when points metres away from your referenced point is only 1.5 metres below.Andrewgprout (talk) 01:43, 4 September 2016 (UTC)

Please check my latest edits at the Aetolia-Acarnania article talk page.We can have the debate over there Weatherextremes (talk) 03:12, 4 September 2016 (UTC)

Source[edit]

What source is this using? The entries for several countries (e.g. Afghanistan and Australia) differ from the figures used in the CIA word factbook. Thryduulf (talk) 13:27, 21 December 2016 (UTC)

  • @Thryduulf: Feel free to correct it and cite CIA world factbook. Vanjagenije (talk) 18:10, 21 December 2016 (UTC)
  • Well, CIA World Factbook is not always accurate... Regarding Australia - see the Mount Kosciuszko article itself for references. Regarding Afghanistan - see this USGS publication. Kószab (talk) 13:39, 22 December 2016 (UTC)
    • Just a note, another Wikipedia article cannot be used as a reference per WP:CIRCULAR. But, feel free to correct the info using reliable sources. Vanjagenije (talk) 22:55, 22 December 2016 (UTC)
    • Man, you misunderstood me. I referred to the references that can be read in the Mount Kosciuszko article. No. 2 and No. 3. in the references chapter of the article. One of them is from Peakbagger, the other one is from the Australian Alps National Parks. Peace and happy Xmas. :) Kószab (talk) 13:16, 24 December 2016 (UTC)
The CIA Factbook is currently one of the least reliable sites for elevations, easy to prove for most areas with the advent of SRTM and the recent release of the more accurate 30 meter SRTM (see NOTE below) postings for areas outside the US. The Factbook has a 20-year-old figure for the Dead Sea that is off by 23 meters, and antiquated or never-valid values off by >130 meters (425 ft.) (!) for high points of Bangladesh, Bouvet Is., Gabon (>500m!), Nicaragua, Saudi Arabia, UAE, Uzbekistan, Wallis & Futuna, and Western Sahara.
More reliably, better sourced sites (that provide sources) include http://www.peakbagger.com/list.aspx?lid=1100 and htpp://www.viewfinderpanoramas.org/elevmisquotes.html , with, for the Andes, http://www.andes.org.uk and on occasion, for volcanoes, http://volcano.si.edu/volcano.cfm?vn=243061
NOTE: SRTM has serious underestimation problems of up to ~40 m for extremely sharp pointed peaks, or those with a high point at the edge of a high vertical precipice. Otherwise, NASA's stated relative vertical SRTM2 accuracy is 10m, absolute 16m (http://www2.jpl.nasa.gov/srtm/statistics.html) (assuming no trees; a dense canopy will somewhat inflate the SRTM2...see http://www.mdpi.com/2072-4292/1/2/36/pdf and pp. 462-3 & 475-6 at https://www.researchgate.net/publication/220605790 DLinth (talk) 04:40, 24 January 2017 (UTC)

Antarctica[edit]

The low point of Antarctica is Deep Lake, in the Vestfold Hills (68.559759°S,78.197761°E), at -50m +/- 1m. See https://data.aad.gov.au/aadc/soe/display_indicator.cfm?soe_id=62 for more details. — Preceding unsigned comment added by 202.87.162.173 (talk) 10:18, 22 January 2017 (UTC)

This Australian website is a reliable source that Deep Lake is has a -50m elevation, but is not a reliable source that this is the lowest surface elevation in Antarctica. I have looked for such a reliable source and cannot find it. The Science paper listed in the table does not have the surface elevation of Deep Lake (as far as I can tell). Can someone supply a reliable source that there is no lake lower than Deep Lake? (I take it we're going to ignore subglacial elevations, some of which are thousands of meters below sea-level). —hike395 (talk) 02:46, 23 January 2017 (UTC)
@DLinth: The Gibson paper in Science (on page 182) states that Oval Lake is at -30 m elevation, but does not state this is the lowest elevation in Antarctica. The Australian website is a reliable source that Deep Lake is at -50 m elevation. Oval Lake cannot be the lowest elevation in Antarctica. We still have no evidence, that there are no lakes with lower surface elevation than Deep Lake. (Absence of evidence is not evidence of absence). —hike395 (talk) 02:55, 24 January 2017 (UTC)
@Hike395: I agree fully... I hadn't seen the Australian source; glad that you just mentioned that. Why not include that source in the article; while it doesn't definitively declare that it's the lowest spot, there sure aren't all that many ice free spots below sea level that could possibly be lower. Anyway, it's a good source to include, I should think. I didn't do the original first 22 Jan Deep Lake edit; I was just trying to find a source for it. DLinth (talk) 03:58, 24 January 2017 (UTC)
@Hike395: @DLinth: GNIS has an Antarctic database. Using this page to search for features lower than -2 (meters), it provides two matches:
name type elevation coordinate GNIS ID
Emona Anchorage Harbor −100 m (−330 ft) 62°37′36″S 60°22′18″W / 62.626667°S 60.371667°W / -62.626667; -60.371667 (Emona Anchorage) 17425
Spillane Fjord Bay −1,250 m (−4,100 ft) 65°20′00″S 62°10′00″W / 65.333333°S 62.166667°W / -65.333333; -62.166667 (Spillane Fjord) 18945
No idea how extensive GNIS datapoints are for the Antarctic, but if either of these are valid, they would discredit the initial assertion. —EncMstr (talk) 06:17, 24 January 2017 (UTC)
Looking at a map for lat/long for both of those, they both map to places in the water. Are they bathymetric features, maybe? —hike395 (talk) 06:59, 24 January 2017 (UTC)

I'm sorry to have added the Deep Lake information anonymously. I have worked on Antarctic Lakes extensively for many years and am very sure (though can never be absolutely certain) that Deep Lake is the lowest point on the continent. It is certainly the lowest point in the Vestfold Hills, one of the largest ice-free areas of the continent. The lowest point of the McMurdo Dry Valleys (the largest ice-free area) is sea level, and there are no lower points in the Schirmacher Oasis, Bunger Hills, or the Windmill Islands. I have searched maps of other areas as well, and have not found any deeper sites. The one other area of Antarctica with below sea level areas of which I am aware is the coastline near the Japanese Syowa base (Lake Hunazoko, 23 m below sea level (see https://www.researchgate.net/publication/228486407_Distribution_of_aquatic_mosses_in_the_Soya_Coast_region_East_Antarctica), and a three other lakes at higher altitude but below sea level). Detailed maps of the Vestfold Hills are dowloadable from https://data.aad.gov.au/aadc/mapcat/list_view.cfm?list_id=45 (scroll down to get to the more general topographic maps). Deep Lake is near the SE corner of map 2. John Gibson — Preceding unsigned comment added by 202.87.162.173 (talk) 11:35, 16 February 2017 (UTC)

Pinging @Andrew Gray: who might have access to survey resources. Jheald (talk) 14:37, 2 March 2017 (UTC)
I agree with John that it seems very likely - there simply isn't much of Antarctica which would be a plausible candidate. (If you'd forced me to guess, I'd have said the Dry Valleys, but they're too high.) I've had a poke around and can't find anyone stating this clearly other than a lot of "lists of lowest points", annoyingly. I say leave it in with a footnote saying "often described as such, but no clear list of lowest points exists" or something similar? Andrew Gray (talk) 20:10, 2 March 2017 (UTC)
