For an Irish summit or High Point list to be classed as 'derived', 50% or more of its locations will have qualified for inclusion from simply having met the criteria of at least one earlier source list. Each of the following compilations is composed mainly of locations imported from third-party original source lists through the processes of duplication, extraction, merging and overlapping.
Irish HuMPs (full list)
(Largely derived from the Irish Marilyns and Sub-Marilyns. Full duplication.)
Irish HuMPs (130m+ prominence band)
(Derived entirely from the Irish Marilyns and Sub-Marilyns. Full duplication and merger)
Irish Sport Hillwalking List
(Derived entirely from the Irish Hewitts / Major Geographical High Points. Full merger.)
Slievemores
(Derived entirely from the Irish Hewitts / Marilyns. Subset.)
500m Prominence High Points
(Derived entirely from the Irish Marilyns. Subset.)
Ireland's Hundred Highest Mountains
(Derived entirely from the Irish Hewitts. Subset)
Arderins
(Derived entirely from the Irish Hewitts / 500-Metre Tops of Ireland. Full duplication and merger.)
Carns
(Derived entirely from the 400-Metre Tops of Ireland compiled by Myrddyn Phillips. Full duplication.)
Binnions
(Derived entirely from the Irish HuMPs. Subset)
Irish Highest Hundred
(Derived entirely from the Irish HuMPs. Subset)

Irish Sport Hillwalking List
(Derived entirely from the Irish Hewitts / Major Geographical High Points. Full merger.)
- 0% based on original research
- 100% derived from other lists
- Duplicated and merged by Kieron Gribbon
- 319 of the 355 locations on this list qualified for inclusion from having featured on the Irish Hewitts and / or Marilyns list. As such, 89% of the locations were identified through original map-based research undertaken by ED 'Clem' Clements.
- 187 of the 355 locations on this list qualified for inclusion from having featured on Ireland's Major Geographical High Points list. Of these, 10 locations qualified because they are 500m Prominence High Points (Marilyns), Province High Points and / or County High Points but do not feature on any of the other five primary High Point lists. As such, 49% of the locations on the Irish Sport Hillwalking List were identified through original map-based research undertaken by Kieron Gribbon.
- 27 of the 355 locations on this list are also County High Points. Although these were researched from scratch by Kieron Gribbon in 2010 for checking purposes, the County High Points list had already existed for several decades. As such, 8% of the Irish Sport Hillwalking locations were identified through original map-based research undertaken by an unknown list compiler.
