Lists Of Mountains In Ireland
In these lists of mountains in Ireland, those within Northern Ireland, or on the Republic of Ireland – United Kingdom border, are marked with an asterisk, while the rest are within the Republic of Ireland. Where mountains are ranked by height, the definition of the topographical prominence used to classify the mountain (e.g. the change in elevation required between neighbouring mountains), is noted. In British definitions, a height of is required for a mountain, whereas in Ireland, a lower threshold of is sometimes advocated. The lowest minimum prominence threshold of any definition of an Irish mountain is (e.g. the Lists of mountains and hills in the British Isles#Vandeleur-Lynams, Vandeleur-Lynam), however most definitions, including the International Climbing and Mountaineering Federation (UIAA) criteria, do not consider prominences below as being mountains (e.g. must at least be an Lists of mountains and hills in the British Isles#Arderins, Arderin or a Lists of mounta ...

Topography Ireland
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the landforms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only Terrain#Relief, relief, but also natural environment, natural, artificial, and culture, cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically relief, even though the United States Geological Survey, USGS Quadrangle (geography), topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultra-prominent Peak
An ultra-prominent peak, or ultra for short, is a mountain summit with a topographic prominence of or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,500 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not ultras because they are connected to higher mountains by high cols and thus do not achieve enough topographic prominence. The term "ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least of prominence. Distribution Currently, over 1,500 ultras have been identified above sea level: 654 in Asia, 357 in North America, 209 in South America, 119 in Europe (including 12 in the Caucasus), 84 in Africa, 54 in Oceania, and 39 in Antarctica.

MacGillycuddy's Reeks
MacGillycuddy's Reeks () is a sandstone and siltstone mountain range in the Iveragh Peninsula in County Kerry, Ireland. Stretching , from the Gap of Dunloe in the east, to Glencar, County Kerry, Glencar in the west, the Reeks is Ireland's highest mountain range, and includes most of the highest peaks and sharpest ridges in Ireland, and the only peaks on the island over in height. Near the centre of the range is Carrauntoohil, Ireland's highest mountain at . The range was heavily glaciated which carved out deep cirque, corries (e.g. the Eagle's Nest), U-shaped valleys (e.g. Lough Coomloughra), and sharp arêtes and ridges (e.g. the Beenkeragh Ridge). The range, part of the Reeks District, is a destination for mountain walkers and climbers and includes some of Ireland's most regarded walking routes such as the 15–kilometre (10 mile) ''Coomloughra Horseshoe'', and the 26-kilometre (16 mile) ''MacGillycuddy's Reeks Ridge Walk'' that traverses the full range; it is estimated th ...

DoBIH
The mountains and hills of the British Isles are categorised into various lists based on different combinations of elevation, prominence, and other criteria such as isolation. These lists are used for peak bagging, whereby hillwalkers attempt to reach all the summits on a given list, the oldest being the 282 Munros in Scotland, created in 1891. A height above 2,000 ft, or more latterly 610 m, is considered necessary to be classified as a mountain – as opposed to a hill – in the British Isles. With the exception of Munros, all the lists require a prominence above . A prominence of between (e.g. some Nuttalls and Vandeleur-Lynams), does not meet the International Climbing and Mountaineering Federation (UIAA) definition of an "independent peak", which is a threshold over . Most lists consider a prominence between as a "top" (e.g. many Hewitts and Simms). Marilyns, meanwhile, have a prominence above , with no additional height threshold. They range from small hills t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ordnance Survey
The Ordnance Survey (OS) is the national mapping agency for Great Britain. The agency's name indicates its original military purpose (see Artillery, ordnance and surveying), which was to map Scotland in the wake of the Jacobite rising of 1745. There was also a more general and nationwide need in light of the potential threat of invasion during the Napoleonic Wars. Since 1 April 2015, the Ordnance Survey has operated as Ordnance Survey Ltd, a state-owned enterprise, government-owned company, 100% in public ownership. The Ordnance Survey Board remains accountable to the Secretary of State for Science, Innovation and Technology. It was also a member of the Public Data Group. Paper maps represent only 5% of the company's annual revenue. It produces digital map data, online route planning and sharing services and mobile apps, plus many other location-based products for business, government and consumers. Ordnance Survey mapping is usually classified as either "Scale (map), lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Placenames Database Of Ireland
The Placenames Database of Ireland (), also known as , is a database and archive of place names in Ireland. It was created by Fiontar, Dublin City University in collaboration with the Placenames Branch of the Department of Tourism, Culture, Arts, Gaeltacht, Sport and Media. The website is a public resource primarily aimed at journalists and translators, students and teachers, historians and researchers in genealogy. Placenames Commission and Placenames Branch The Placenames Commission () was established by the Department of Finance in 1946 to advise Ordnance Survey Ireland and the government of what the Irish name of places should be. Although both the 1922 Constitution of the Irish Free State and the current constitution adopted in 1937 recognised Irish as the national language, the law in regard to placenames was carried over from the 19th-century UK statutes which established the Ordnance Survey and Griffith's Valuation, under which only an English-language name had offi ...

Mountaineering Ireland
Mountaineering Ireland is the representative association for hikers and mountaineers on the island of Ireland. It is recognized by both Sport Ireland, the Irish authority for sport, and Sport Northern Ireland, the corresponding authority of the Government of Northern Ireland, thus operating across the island of Ireland. The association has been an International Climbing and Mountaineering Federation (UIAA) member since 2004, as well as a member of other federations. The association is also a publisher of walking and climbing guides. History The association was founded in 1971 as the "Federation of Mountaineering Clubs of Ireland" (FMCI), by eight clubs with 300 members at the time. In 1990 it became the "Mountaineering Council of Ireland" (MCI). The current name was adopted in 2009. Mountaineering Ireland became a member of the Olympic Council of Ireland (OCI) in June 2018, with Sport climbing set to become an Olympic sport at the 2020 Tokyo Olympics in 2021.

Topographic Prominence
In topography, prominence or relative height (also referred to as autonomous height, and shoulder drop in US English, and drop in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. The key col ("saddle") around the peak is a unique point on this contour line and the ''parent peak'' (if any) is some higher mountain, selected according to various criteria. Definitions The prominence of a peak is the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following manner: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''highest saddle (landform), saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting paths; the prominence is the differ ...

Hill Lists Diagram Ireland
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit, and is usually applied to peaks which are above elevation compared to the relative landmass, though not as prominent as mountains. Hills fall under the category of slope landforms. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the UK government's Countryside and Rights of Way Act 2000 defined mountainous areas (for the ...

Ordnance Survey Ireland
Ordnance Survey Ireland (OSI; ) was the national mapping agency of the Republic of Ireland. It was established on 4 March 2002 as a body corporate. It was the successor to the former Ordnance Survey of Ireland. It and the Ordnance Survey of Northern Ireland (OSNI) were themselves the successors to the Irish operations of the British Ordnance Survey. OSI was part of the Irish public service. OSI was headquartered at Mountjoy House in the Phoenix Park in Dublin, which had previously been the headquarters of the British Ordnance Survey in Ireland until 1922. In March 2023, the Ordnance Survey was dissolved and its functions transferred to a new body called Tailte Éireann, which also incorporates the Property Registration Authority and the Valuation Office. Organisation Under the Ordnance Survey Ireland Act 2001, the Ordnance Survey of Ireland was dissolved and a new corporate body called Ordnance Survey Ireland was established in its place.
