These lists are currently maintained by MountainViews, the group of people who have come together to develop the MountainViews service.
The list in use started with the 2000ft list of Rev Vandeleur (1950s), the 600m list based on this by Joss Lynam (1970's) and the 400 and 500m lists of Michael Dewey and Myrddyn Phillips. Extensive revision and extra data has been accepted from many people including Brian Ringland, Paul Donnelly, Simon Stewart, John FitzGerald, Paul Tempan, Denise Jacques, Colin Dalton, Brendan O'Reilly and others.
Irish forms of mountain names have been compiled by Paul Tempan, along with translations and notes on the summits and their names (2004-). The main sources for names are Ordnance Survey maps (OSI and OSNI) and the databases of An Brainse Logainmneacha / The Placenames Branch and of the Northern Ireland Place-Name Project. Others are gathered from place-name surveys (see article in Resources), and some are the result of original research by Paul Tempan
Popularity information is based on the over one thousand people using MountainViews to record what summits they have climbed. (2002-)
Mountain rating information is based on thousands of ratings of summits (in seven categories) by MountainViews members. (2002-). Position information is continuously being revised by the online GPS measurement system.(2004-)
The email address for Mountain Views is group@mountainviews.ie

Note: For most of the lists inclusion is based on absolute height listing. Mountains must be 400m or above with a 30m drop (aka prominence) from the summit qualifying them as a separate top or 150m or above with a prominence of 150m. The list will be refined as checking proceeds. The aim is to produce a "strict" or "standard" list adhering to the prominence requirement and an "inclusive" list including those that didn't appear to quite make it or which have some other intrinsic interest. The inclusive list maximises opportunities for comments, photos and inclusion in walks, all objectives of this site.

The "100 Local" list includes the first 100 summits we list nearest to where you have told us your location is. The purpose of this is to provide a list whose completion requires less travelling.
The "100 Rated" information from each of thousands of individual rating entries provided by members to rank summits and provide a unique and hopefully useful selection.
The "100 Highest" list has been introduced to give a height based list, not too long, with a spread of locations for Ireland. The smallest is 714m
The "900m" list has the same summits as a 3000 footer list, the height of the Scottish Munros (3000 foot= 914.4m). This list is short and oddly bunched in one main area in Ireland with no summits north or west of Wicklow and is included for historical interest as it doesn't make much of a long-term challenge or interesting agenda.

All lists can be sorted by any of their fields such as "height" or "popularity". For most of the height based lists it is possible to further select by area.

Mountain Views is an online service developed by Simon Stewart (website: Hillwalking in Ireland) and others using data from a variety of sources. The software is copyright Simon Stewart and was developed with open source tools starting from the launch in June 2002.   Help from Eoin O'Sullivan ( www.hillwalkers.com) is greatfully acknowledged. Additional data about map boundaries came from Tom of Megalithomania.
Digital elevation data used to construct the topographical maps ("SRTM data") came from a NASA shuttle mission of 2000. The data was released in early 2004. The version we have used was partially cleaned up by Geomantics in the UK.
Mapping data for roads, placenames and water features was supplied by Ordnance Survey Ireland. This material is copyright Ordnance Survey Ireland and we would ask you to respect this copyright. We would like to thank Hugh Mangan of Ordnance Survey for helping us obtain this mapping in 2005.

Should you be experienced in any of the skills required such as PHP, website design, cartographic or GIS principles, Linux, Apache, MySQL, terrain modelling and wish to contribute, the email address for Mountain Views is group@mountainviews.ie. We would love to hear from you.

As of august 2010 around seven hundred people have contributed to MountainViews. There are some 4580 mountain comments, 1480 summit position corrections, 3495 photos etc.  Thanks to all!
