Database of British and Irish hills: revision history
v15.4.2 26/02/2017Corrected coordinates for 19275 Butcherfield.
v15.4.1 15/02/2017Fixes two bugs in the Access version, one causing hills on Irish islands being duplicated in searches, the other affecting the Export Logs option when you choose the file location.
v15.4 09/02/2017Routine update with three significant Marilyn relocations, a few promotions, and a raft of new Tumps.

Key data changes - Ireland
ArderinsThe Arderin summit of Pigeon Rock Mountain (43B) has been assigned to new hill 21450 and named Pigeon Rock North to distinguish it from the Hump and Myrddyn Dewey, hill 20677 (renamed Pigeon Rock South) and to recognise hill 21450 as a new Submyrddyn Dewey. Current maps mostly give the same height to both summits but the old 6" map makes the south top 6ft higher.

Design changesSMC and Marilyn parents now have both their hill name and hill number shown in Access and Excel/csv, thus aligning with Hill Bagging. In Excel/csv, the Parent (Ma) column gives the hill number for the parents themselves as well as their children (if any), with '0' for non-Marilyns without parents, so that a sort on this column will return the parent and all its children. This has not changed from the previous version. The other three columns are only populated for children of parents.
DocumentationA new document Accuracy of heights from OS maps has been issued for the benefit of users with a "scientific" interest in hill data. Our recent document Using an Abney Level to Measure Relative Heights is relevant to anyone owning an Abney Level or thinking of purchasing one to add survey data to their GPS contributions.
v15.1 24/12/2015Routine update with only a few significant hill changes but many new surveyed heights from Alan Dawson and more from Myrddyn Phillips and G&J Surveys. Rationalisation of the Parent field.
Design changesThe Parent (Ma/M) field has been replaced by two new fields giving the SMC parent and Marilyn parent. Parent (SMC) gives the Munro parent of Munro Tops and the Donald parent of Donald Tops. The Munro parent is not given for Corbett and Graham Tops following the removal of the CTM and GTM categories in the previous release. Parent (Ma) gives the hill number of the Marilyn parent. In the Excel version, Parent (Ma) also gives the hill's own number for hills that are parents and replaces the Parent Sort column given in previous releases. Further details are in the Database Notes.
A new Donalds Change Register was recently added to the site.

SubsThe following are in addition to the changes resulting from the promotions and deletions above.
5225 Old Radnor Hill (31B) – reinstated
19174 Creag Stalcair East Top (5B)
Map 1:25k fieldOS has renumbered some of the Explorers (101-470) into the Outdoor Leisure range (OL 1-63). So far as we can tell, the area coverage has not changed. As many users will have the old maps we give both the new OL numbers, prefaced by OL, and the old Explorer numbers. Note that OS has reused some OL numbers that in the past mapped completely different areas. For example OL10 was originally Yorkshire Dales (South), subsequently replaced by OL2 Yorkshire Dales (South) and covering a larger area; the new OL10 is Arundel & Pulborough.
We are grateful to Toby Thurston for alerting us to the changes and for supplying revised polygons for the map sheets.
Key data changes - Ireland20757 Knocknaveacal North Top has been deleted from the Myrddyn Deweys. It was deleted from the Arderins in the previous release.
v15 21/09/2015Major release with some new fields and a simplification of the classification scheme for hills belonging to the Sims and their subs that may affect third party applications. A large number of hill reclassifications, the majority arising from surveys by Alan Dawson, and the usual raft of changes to the Tumps. Myrddyn Phillips has also contributed many survey results.
Design changesThe CTM, CTC, GTM, GTC, GTG and GTH subcategories have been dropped. They have been replaced in the classification field by CT and GT, which already existed as searchable categories in Access, Excel and Hill Bagging. A new Subsim category has been created for hills above 600m with drop 20-29m and the sMur, sCT, sGT and sHew classes have been dropped. The position of Sim has been elevated and Murdo/CT/GT lowered in the Classification field, dropdown lists and tables. This has entailed a reordering of the 1,0 columns in Excel. The changes follow an extensive discussion on the rhb group in January initiated by Alan Dawson, who wishes to phase out the Corbett Tops and Graham Tops, and reflects the consensus reached in that discussion.
A new field for Island has been added. For details see the Database Notes. In Access, it is searchable by selecting Island from the Area/Region dropdown box. The option previously called Island has been renamed SIB Area. In the search results screen giving detailed hill data, the Island name appears in the first row of the Areas/Regions table and the SIB area in the second row. These are followed by the RHB section and the Topo Section (see below).
A new County field, giving the Current County or Unitary Authority (CoU) membership of all hills in the database, has been added to the Excel/csv versions. This information was previously available only in Hill Bagging and (as a search option) in Access. The Excel/csv column giving the relevant county or counties for County Tops has been retitled County Top.
A new field for Topo Section has been added. These are geographical areas defined by Mark Jackson for the Humps and Tumps, previously available in Hill Bagging. In Access, the Topo Section is a searchable option in the Area/Region dropdown box.
Some area names in England, Wales and Scotland that do not feature in the Nuttalls, Wainwrights, Dewey or Donald guides or SIB Maritime Regions have been removed from the Area field.
The Tumpnumber and Tumponly columns in the Excel version have been removed. They were introduced to faciliate migration of users' records from the P30 Appendix to the DoBIH v14, but we expect all users of the Appendix have now migrated.

Other new hills26 other hills have been added to the database, comprising 14 Yeamans, 6 Clems and 6 hills that would have qualified as Subdonald Deweys in a private list of David Purchase's that circulated for several years before the category was adopted by the DoBIH. The 20 Yeamans and Clems have an "O" code in the Classification field and the other 6 hills an "Un" code. All the Yeamans and Clems are now present in the DoBIH although these 'historic' lists are not currently supported. We thank Bernie Hughes for providing details of the hills. A further two hills became Tumps and another (noted above) became a Subdewey and Subdonald Dewey after reviewing their data.
Key data changes - Ireland
20695 Coomcathcun South Top [Slievenashaska] (50B)
21446 Brandon Far North Top (49A)
The Northern Ireland Current County/UA Tops have been realigned to reflect the reduction from 26 to 11 local government districts in April 2015.
There have been a number of changes to hill names, initiated by MountainViews.
Note that MountainViews has now added the Arderin Begs (H500-599, P15-29) and some hills with lower prominence to its site. All the Submyrddyn Deweys (H500-609, P20-29) are present in MountainViews except 21186 Conigar South Top.
v14.3 30/04/2015Routine update with the usual raft of changes to the Tumps arising from the data review, now complete. New island list.
We are grateful to Alan Dawson, Myrddyn Phillips and MountainViews for survey data, and to Alan Dawson for further hill name changes.
New listsThe SIBs (Significant Islands of Britain) have been added. These comprise the Main SIB category as defined in Alan Holmes's publication, currently 556 hills of which 62 are new to the database.

21252 Meakstown, Dublin City top (56A) relocated 400m east
Design changesThe xG classification has been added for deleted Grahams.
The Area field has undergone some changes. For islands, the island name is used if there are 5 or more Tumps on the island landmass. For islands with 4 Tumps or fewer, the area name is now taken from the maritime Region set out in The Significant Islands of Britain (SIBs) by Alan Holmes. Some SIB Regions have been manipulated to comply with this rule, e.g. "Skye and surrounding islands" is split into "Skye" and "Skye surrounds". We have removed some area names in England and Wales of doubtful value or which have not been used consistently.
v14.2 23/12/2014Routine update with changes and new data arising from the ongoing Tumps review and surveys by Alan Dawson, Myrddyn Phillips and G & J Surveys. Background on most reclassifications and major relocations is given via links in the appropriate Change Register in the Database Notes. We thank Alan Dawson for reviewing hill names of Sims and Subsims and suggesting other data changes.

New listsThe Fellrangers (a new Lake District list for which the LDWA has created a Hillwalkers Register) have been added. All the hills were already in the DoBIH with the exception of 8028 Wallowbarrow Crag which was in the P30 Appendix.
Hill namesAbout 85 Hebridean hill names have been changed from English [Gaelic] to Gaelic [English]. The Gaelic names have been shown on OS Landranger maps for many years. A few other Scottish hills have seen name changes, partly in response to the tables on the SMC website.
Key data changes - Ireland
20665 Corronoher (48B) is a new Marilyn
21207 Ott Mountain (43B) is a new Arderin
The Binnions have been redefined as hills below 400m in height with a drop of at least 100m (previously it was 150m). There is one difference from the subset of Humps below 400m; see discrepancies. We prefer Knockroe to Ballydorgan as is 8ft higher on older maps.
New fieldsParent (Ma/M), Parent Number, Parent Sort
The parent prefacing the hill name in Munro, Corbett and Graham Tops (and their subs and deletions) has been transferred to a separate field. Thus the Munro Top previously named Cairn Gorm - Carn Lochan now has Carn Lochan in the Name Field and Cairn Gorm in the new Parent (Ma/M) field. We have extended the use of this field to identify lower children of the same parents, and children of lower Marilyns. The parent's hill number is shown in the adjacent field. For more information see the Database Notes.
A facility to search on either the parent name or number has been added to the Access database and to Hill Bagging. The search results will include the parent. In Excel a related facility is provided by a Parent Sort field (to the right of _Section) in which parents have their own hill number copied to this field. See the Database Notes for more information on this field and on a Query in the Access version that performs the same function.
The following fields are present in the Excel and csv versions and in the Hills table of the Access version.Tumpnumber
For hills transferred from the P30 Appendix, the previous hill number in the 100000 series. The presence of a Tumpnumber does not mean the hill is necessarily a Tump, as some have been demoted to Unclassified. This field will become obsolete when all users of the P30 Appendix have moved to the new environment.
Tumpnumber 110803 Eilean Mor was found to duplicate hill 101875 in the P30 Appendix and had been deleted from Hill Bagging (it had no logs). In order to simplify the transfer of users' records from the P30 Appendix to the DoBIH, we have reused this Tumpnumber for the most recently added new Tump, hill 18745. It is highly unlikely that anyone will have logged Appendix hill 110803, but if you have, transfer your record to hill 9906.Tumponly
An identifier taking the value of 1 for hills formerly in the P30 Appendix which have not acquired any other classification (e.g. sHu, Fel) in the meantime. Used for the "Exclude minor Tumps" filter in Access and "Include all Tumps" filter in Hill Bagging.MVNumber
For Irish hills, the MountainViews hill number, as given in the hill page's URL on the MountainViews website which takes the form mountainviews.ie/summit/xxxx where xxxx is MVNumber.
Tump totalsThe Access version now includes All Tumps in the User Totals query. The Excel and csv versions have a Tu column to the left of the Sim column. Hill Bagging offers "Tump (all)" in the League Tables.
Excel/csv versionsWe no longer provide separate GB and Ireland extracts. As the hills in the P30 Appendix are now part of the GB number sequence, there is little to be gained from issuing a GB only file, which would reduce the file size by only 7%. There were never many downloads of the Ireland only file. Users who do not require the Irish hills can delete the rows with hill 20001 onwards.
Transferring your records from the P30 AppendixAccess users should use the import facility accessible from the Welcome screen. Excel and csv users please follow these instructions.
v13.3 24/12/2013Update of British lists and addition of the Synges. No significant changes in Ireland.
We are grateful to Alan Dawson and Dave Marshall for their contributions to data revision, and to Alan Dawson and MountainViews for survey data.

The classification code '4' now applies to 400-499m hills in Britain, as in Ireland. The majority of hills of height <490m are still to be found in the P30 Appendix. Codes '3' '2' '1' and '0' have been added for hills in the other height ranges. This will make it easier for Tump enthusiasts to filter subsets when they merge the Excel version with the P30 Appendix.
Geograph links have been modified. When a 10-figure GR exists, the blue circle will centre on the true (i.e. map) grid reference rather than, as previously, the Garmin GPS version in the 10-fig GR field.* When no 10-figure GR exists, the blue circle will centre on the SW corner of the square, e.g. for NN123456 the circle will be at NN 12300 45600, rather than in the centre of the 100m square. This positioning now aligns with the Streetmap links. See Database Notes for an explanation of the difference between a GPS and a map grid reference. A new field GridrefXY in the Excel and csv versions gives the 10-figure grid reference with the systematic component of the GPS error removed.
*We have had a report that on some PCs the coordinates displayed by Geograph are displaced from their correct position on the zoomable map. This becomes apparent when you hover or click with the mouse. This glitch has nothing to do with the database.
Revision dates from 2009 onwards give the date applied in Hill Bagging.

Key data changes - IrelandTwo more lists on the Mountainviews site have been added. We thank Simon Stewart for permission to reproduce these lists.
The Carns are hills 400-499m high with a minimum drop of 30m. The list has a number of differences from our own listing of 400-499/P30 hills, which are identified with the classification code 4. This is an extension of the '4' code which in previous releases applied only to 490-499m hills, as is still the case in Britain.
The Binnions are hills below 400m with 150m drop. The list is not identical to the subset of Marilyns below 400m.
The classification codes Ca and Bin are not shown in the Classification field but appear in the search dialogs and as columns in the Excel and csv formats.
DocumentationA new Marilyn Change Register is accessible from the Database Notes. Change registers for the Munros and Corbetts were updated in February.
P30 Appendix 09/05/2013P30 Appendix added to Hill Bagging with optional filter, Excel file transferred to DoBIH site. Major revision with enhancements to Excel version to match DoBIH.

Key data changes - IrelandThe Vandeleur-Lynam and Arderin lists have been added. Both lists align with Mountainviews, although data details may differ.
The County Tops have been expanded to include the 26 local government districts of Northern Ireland that came into existence in the 1970s, together with four City Councils in the Republic of Ireland and three new counties that emerged from the historic 'Dublin'. Their classification code is CoU. In 2014 Limerick City and North Tipperary will no longer exist and their tops have not been included. Hills 21242-21253 are new; the others were already present as members of other lists.
20445 Crocknasmug has been reinstated as the Marilyn, replacing 20886 Crockaulin
20005 Caher West Top, 20033 Gearhane [An Gearan] and 20206 Corrig Mountain are deleted from the Hewitts

Other data changesFurths (hills outwith Scotland over 3000ft high listed in Munro's Tables) are identified with classification code F.
Design changesThe OS Get-a-Map field has been replaced by a link to Geograph mapping.
The database will run in 64-bit Access.
DocumentationA table of discrepancies where the data are at odds with a hill's classification is linked from the revised Database Notes.
v12.1 17/02/2012Routine update to correct a few errors in the new lists in v12.0, implement recent changes and update 10-figure grid references from the GPS database. The remaining subs for the Irish lists have been added, with the result that the database now covers all of GBI down to 490m with 20m drop, and lesser heights with 90m drop.
Key data changes - Britain7824 High Billinge (Section 36) replaces 5339 Hangingstone Hill - Pale Heights as Hump following a survey.
7830 Liddington Hill (39) replaces 5381 Liddington Castle as Hump and Swindon UA Top. The old summit is lower if you discount the man-made ramparts.
3481 Y Glog [Draws Drum] has been relocated 350m north to the 574m spot height on the vector map as this is 1m higher than the spot on the 1:25k map. However the location of the Dewey on the ridge is uncertain.

Other data changes385 Sgairneach Mhor: corrected height of this deleted Munro Top
686 The Saddle - Trig Point: new 1011 height from 1:25k map. Evidence for the competing summit locations is summarised in the Database Notes.
2457 Haystacks: we have moved the summit to the Dewey and mentioned the Wainwright/Birkett summit in Comments. We have adopted a new policy of giving precedence to a prominence based list over a subjective list when the summits are at slightly different locations. It may take a while to bring other hills into line with this policy.
2557/2927 Wether Hill: heights and drops changed. Old maps and and a survey by Abney Level provide clear evidence to support the south top being higher (see Database Notes). The Nuttalls have been notified. For the time being the Nuttall stays at the northern summit.
2605 Bannisdale Fell - Long Crag: summit moved to the Birkett/4 and WOF summit transferred to Comments

Link to Summits and Cols protocol used by the editorial and survey teams to define the location of summits and cols.
The Munros and Tops 1891-1997 has been brought up to date.
v12.0 27/11/2011Major release with new lists, coverage of Ireland, and changes to the database design. Great Britain is now covered down to 490m in height with 20m of drop, and to 90m of drop for lesser heights. Ireland is covered down to 600m in height with 20m of drop, to 490m with 30m of drop, and to 90m of drop for lesser heights. Paddy Dillon's list of Irish 2000ft hills is also included. We have extended coverage to the Channel Islands, adding three Humps and a Subhump in the newly created section 57. There are now 7819 British hills, an increase of 39% on the previous version, and 1167 Irish Hills.
We have discontinued the non-relational Access versions.
Classification codesWe have adopted Alan Dawson's redefinition of subs as hills falling short by 10m of drop. Hills falling short on height are no longer subs but are subsumed into other lists. The Subgraham category has been removed. Sorry to those who dislike changes, but the addition of the subCTs, subGTs and sub5s would have led to many more multiple classifications and created additional categories of "double sub". For further explanation see the Database Notes [now removed].
We have removed all deletion categories except those for the SMC lists and the Nuttalls. Again, please see the Database Notes for the rationale. In their place, we are using the Comments field to record deletions in other categories. We plan to add change registers for Marilyns, Deweys etc. in the Database Notes, in a similar format to the change register for the Humps.
The codes 5D and 5M identify the listings of the 500-609m hills in the Scottish Lowlands and Ireland, known as Donald Deweys and Myrddyn Deweys, respectively. We have used 5H for the extension to the Scottish Highlands and named the hills Highland Fives. We considered using the code 5 for all these lists as in Rob Woodall's files on the rhb group, but it would have complicated the search facility for the Donald Deweys, and hills on the England-Scotland border would not have been identified as belonging to both lists. We have not subdivided the 4 and s4 categories, which cover only 490-499m hills at present.
Design featuresThe Access version has a new facility for searching within a specified distance of a grid reference.
We have restructured the Classification field so that multiple categorisations appear in a rational order.
RenumberingTwo redundant hill numbers have been reused.
Key data changes5636 Saugh Hill is now a twin Marilyn of 1734 Troweir Hill.
3545 Beefstand Hill is no longer a Dewey. It has been established beyond doubt that the summit lies in Scotland.
2230 Fan Brycheiniog has been replaced by 5603 Fan Brycheiniog - Twr y Fan Foel as Marilyn, Hewitt and Nuttall.
1024 Beinn a'Chlaidheimh has been surveyed as 913.96m (2999ft). The result has been accepted by the OS, and Get-a-map now gives a summit height of 914m instead of 916m. The SMC has not yet demoted the hill to Corbett.
5478 Silverhill is no longer a twin County Top of Nottinghamshire. For details see the survey report.
Irish hills are new to the database, but owners of the TACit publication should note the following changes:
v11.6 31/03/2011Routine update with 195 new 10-figure grid references, promotions/demotions detailed below, and various minor corrections. Drop has been added for the 192 hills lacking a figure in v11.5. 1635 hills now have an entry in the "survey" field.
Some discrepancies in the Area field between the relational and non-relational versions of the database have been resolved. A bug has been fixed in the relational database that was preventing searches on certain combinations of criteria.
Excel and csv versions have a new field with links to the hill-bagging website.
Key data changesThere are three changes to the Deweys:
5635 Kirkby Fell is promoted
There are a number of changes to the Humps. For a listing of all changes since the original publication, see Changes to the Humps.
2865/2866 Seager Hill has been de-twinned. Hill 2865 is still the Marilyn but the south summit is now thought to be lower on the basis of levelled heights on old maps. These replace the 269m air heights from the 1:25k map.
Two DoubleSubMurdos and two DoubleSubHewitts have been added. These categories will be reclassified as SubCTs and SubDeweys in version 12.
v11.5.1 – Access versions only
Relational 24/01/2011Fixed bug causing two hills on the Scotland–England border in RHB/TACit lists being duplicated in searches and not being returned in searches on section 28B.
Added new search by map number; replaced dropdown box for Country by checkboxes.
Non-relational 21/12/2010Fixed bug in non-relational Access versions (2000 and 97) giving incorrect totals in Nuttalls queries.
v11.5 16/11/10A significant release with new functionality in the relational Access version, three demotions and numerous data additions and amendments.
Database designThe relational Access version offers the following new features:
Key data changes2734 Lovely Seat is no longer a Marilyn.
3396 Cerrig y Ieirch [Moel Llechwedd-gwyn] and 3609 Linghaw are no longer Deweys.
The true summit has Rhiw Gwraidd (35A) has been identified and the Marilyn moved from hill 2196 to 2197.
2303 Cairn Hill has had its xDT classification removed. Neither Cairn Hill nor the other English hills appearing in Section 12 of the Donalds listing up to the 1990 edition of Munro's Tables — hills 2302, 2306, 2307, 2309 and 2310 — were given a Top Number. Neither did they appear in Table 2 The 2,000 feet hills arranged in order of altitude. It seems clear from Percy Donald's introduction to the 1953 edition that he regarded the English hills in the Cheviots as an addendum rather than part of the list, so they cannot be regarded as having been Donalds or Donald Tops. The DoBH has never classified the other five hills as xDT so Cairn Hill was an anomaly.
Hill 2304, formerly Hangingstone Hill, has had its data removed and is now unassigned. We had already transferred the deleted Nuttall to 1846 Cairn Hill West Top in v11.0. The change will prevent hill 2304 from being returned in searches on Hangingstone Hill and potentially causing confusion.
We have rationalised the Area names for hills on the Scotland-England border in the non-relational versions of the database. A few hills were causing a problem by belonging to "Cheviots" in the Nuttalls list and "Roxburgh and Cheviots" in the Donalds. In all versions of Munro's Tables prior to 1997 this area is split into "Roxburgh" (section 11) and "Cheviots" (section 12). The SMC amalgamated the two regions when they removed Auchope Cairn and the six unnumbered English tops in 1997, leaving only three hills in total. We decided the simplest solution was to revert to the pre-1997 sections, as "Cheviots" is also the Nuttalls area name. Accordingly, 1906 Cauldcleuch Head is now in "Roxburgh", and 1846 Cairn Hill West Top, 2303 Cairn Hill and 2305 Auchope Cairn are in "Cheviots". The relational Access database is unaffected because its structure allows a hill to carry more than one area name, so hills appearing in both lists will appear under "Roxburgh and Cheviots" in a search on Donalds areas and under "Cheviots" in a search on Nuttalls areas. We have fixed a bug that caused Windy Gyle to be omitted from a search on Roxburgh and Cheviots.
2318 Housedon Hill: the summit has been moved to the south top (the original location in The Relative Hills of Britain) following an Abney Level survey. The 267m spot on the 1:50000 map is confusing as it is superimposed on a 260m contour and is nowhere near the northern summit. 19th century 1:10560 maps give the correct position (877ft).
The historic county top of Denbighshire has changed from 2089 Moel Sych to 2087 Cadair Berwyn. The new summit for Cadair Berwyn did not appear on pre-metric OS mapping.
There are location changes for Nottingham, Wigan and Blackpool Unitary Authority tops. 5528 Mapperley is no longer a twin CoU as 5527 Nottingham M1 is thought to be higher.
Two new unclassified hills have been added following surveys to determine possible Nuttall or Dewey qualification.
In addition to the above, there is the usual raft of minor changes arising from GPS measurements, surveys, and new hill names or spot heights on OS maps. The number of hills lacking a figure for drop (none on prominence based lists) has reduced to 172. We give col locations for 4336 hills.
LicensingWe now license the database under a Create Commons Attribution licence. Commercial use of the data is permitted.
v11.4 31/03/2010A significant upgrade with over 650 new or amended col grid references, 286 new drops, 117 new 10-figure grid references, 102 more surveyed hills, and changes to the primary data of 186 hills. 205 hills still lack a figure for drop but none are on prominence based lists.
2607 Baystones is demoted to SubMarilyn for the second time.
3343 Iwerddon has been deleted from Dewey's list.
366 Meall Glas Choire and 1006 Lord Berkeley's Seat become new SubMurdos.
Two Humps have been deleted: 5275 Mynydd Dinas and 5308 Quarrystone Bank.
Twin Humps, defined as having at least 30m of drop, have been added. A query for Hu= has been added to the Access database.
We have added a former Hump whose deletion predates the addition of Humps in v11.0: 5624 Stacaiseal. Another "old" deleted Hump, 2954 Binnein an Fhidhleir, was already there as a CTC but we have added the xHu classification.
The two hills in section 20D have been moved to 20A. Section 20D was briefly created for Colonsay but subsequently scrapped, so is not a valid RHB region. Two further errors in the Section field have been corrected: hill 587 has been moved to 8B and hill 5605 to 38B.
Many hill names have been corrected and or had alternative names added, generally due to new names or changed spellings appearing on OS maps.
The Comments field has been overhauled. 24 entries deleted in error in v11.2 have been restored. We no longer comment on revisions of a routine nature, e.g. small changes in height or grid reference.
Two minor bugs affecting searches in the relational Access database have been corrected.
v11.3 08/12/2009Minor upgrade to correct errors in v11.2.
v11.2 20/11/2009A significant release with changes to the primary data of ca. 250 hills including many new and updated col grid references. 10-figure grid references are now supplied for 3190 hills, an increase of 466 from v11.1. 1182 hills have been surveyed.
Database designFollowing requests, two new lists have been added. They can be accessed via the main search screen in the relational Access database and by numbered queries in the non-relational version. New columns are given in the Excel and csv versions.
A few glitches in the previous version have been sorted out. In the relational Access version, "sort by date" now functions correctly; sort by drop has been added; and all lists including Buxton & Lewis, Bridge and Trail 100 are available in the search dialog. In the non-relational Access version, the former Query 60 "Sorted by Climbed date" functions correctly.
Key data changes900 Sgurr nan Ceannaichean is demoted from Munro to Corbett. See the Database Notes.
5619 Carn Bad nan Luibhean is a new Hump.
Seven Humps have been deleted: 3014 Sgor Gaibhre - Meall a'Bhealaich, 4921 Hill of Colvadale, 4998 Northballo Hill, 5006 Mounthuillie, 5038 Loch Hill, 5077 Barskeoch Hill, and 5600 Dirrington Little Law.
Hill 5618 has been created for the Hump summit of Hampsfell. 2696 is now reserved for the Wainwright Outlying Fell.
1267 Beinn Dearg Mheadhonach: classification corrected from GTC to GTG.
1321 Beinn Chreagach (Mull): moved to NM 51988 21701, 240m east of the main cairn and 1m higher. Most people are likely to have been over the highpoint if using the obvious route from the Carsaig road.
739 Luinne Bheinn has been relocated back to the "official " summit.
A number of hills, all but three of them Humps, have had their Section/Region corrected. 1564 Liuthaid (Marilyn) and 1944 Ayton Hill (SubMarilyn) were incorrectly designated in the original sources.
20 hills have had their name or spelling changed, and another 17 have newly added alternative names. The latter include a handful of Gaelic alternatives that have recently appeared on OS maps.
Many hills have seen minor changes in height, drop or grid reference. We have started to overhaul the col data, which has resulted in quite a lot of changes to col positions; others will undoubtedly follow in future releases.
v11.1 06/07/2009Maintenance release mainly to correct errors in v11.0.
A small number of classification errors have been corrected. With the exception of hill 28 Stob Binnein - Stob Coire an Lochain, wrongly classified as a Marilyn, they affect only the relational version. Relational version allows searches on deleted Corbetts and Double Subs.
RHB section numbers corrected for a number of Humps.
Gaelicised hill names appearing on recent OS maps added in brackets.
Summit of 4817 Ben Hogh on Coll relocated to the SE top.
About 20 heights and drops of Humps updated. Survey data added for a further 10 hills.
v11.01 23/06/2009Bug fix for the relational Access version.
v11.0 22/06/2009Major release with nearly 2000 new hills, new data fields, and provision of both non-relational and relational versions of the Access database. Simon Edwardes and George Gradwell have joined the editorial team. The interactive database at www.hill-bagging.co.uk and the Database of British Hills now share the same data.
Database designGraham Tops, County Tops, Birketts and Humps have been added.
New fields have been added for drop, col height and col location.
Latitude and Longitude are now given in signed decimal format.
The classification codes have changed. Sorry if this confuses people, but we were running out of letters and the additional lists would have put a strain on the system. The new codes are more intuitive, and those for the Corbetts and Grahams and their tops align with the TACit Tables. We think most of the codes will be interpretable without reference to the key.
10-figure Grid References are given to the nearest 1m rather than 5m. Many measurements now have improved accuracy from averaging several independent GPS readings, while a growing number of others are from highly accurate differential GPS measurements. (We have always quoted OS data on trig points to 1m.)
A new relational version of the database is available in Access 2000 upwards.
Key data changes14 Creag na Criche, 1482 Sail Chalmadale and 2051 Mynydd y Cwm: promoted to Marilyn.
2828 Raw Head: demoted to SubMarilyn after exhaustive surveying.
4382 Gairbeinn - Carn Leac East Top: new Corbett Top. The Graham Tops listing includes two summits added since the original publication.
3267 Beinn Dearg North Top: deleted Corbett Top.
3385/3386 Pen y Bedw: The east top (hill 3385) replaces the west top (hill 3386) as the Dewey.
2381/3728 High Stile: We have created a new record for the Wainwright summit, hill 3728. This was necessary because Birkett lists the Wainwright and Marilyn/Hewitt/Nuttall (hill 2381) as separate tops. You may need to adjust your records.
2667/3863 Top o'Selside: We have created a new record for the Wainwright/Birkett summit, hill 3863. This was a borderline decision as it is only 100m from the Marilyn but we think it far from certain that walkers would automatically visit both summits. You may need to adjust your records.
2607/3838 Baystones [Wansfell]: We have added a new record for the former position of the Marilyn as Birkett gives this location.
2304 Hangingstone Hill: This hill has been declassified as the deleted Nuttall has been transferred to 1846 Cairn Hill West Top. The grid reference for the summit, established by an Abney Level survey, is 70m SW of the fence junction and plots exactly on the England–Scotland border (from the OS Admin Meridian data). There is therefore no justification for listing the deleted Nuttall separately from the Donald Top.
Database designWe have rationalised the way we present data in the various co-ordinate fields and added new fields for latitude and longitude. All entries in the 10-figure Grid Ref field are suitable for input to hand held GPS units, including those derived from the OS trig point database. Entries in the xcoord and ycoord fields are true OSGB36 National Grid, i.e. those derived from Garmin GPS measurements have had the systematic error removed. The new Latitude and Longitude fields are to the WGS84 datum. For further details see the Database Notes.
Data changes2033 Mynydd Graig Goch: As many readers will have heard on the national news, this former Dewey has been shown by surveying to be over 2000ft high. In consequence it becomes a Nuttall and Hewitt.
3686 Botley Hill: The new location has been confirmed by surveying.
3385/3386 Pen y Bedw: A survey by Abney Level suggests that the East Top is 1-2m higher than the West Top. The drop between them appears to be less than 30m. An accurate levelling survey is planned. If the above is confirmed, the West Top, the original Dewey, will be deleted.
2235 Bwlch y Ddwyallt [Gwaun Cerrig Llwydion], 3612 Meugher, 3642 Oliver Hill: transcription errors in the grid references have been corrected. Some other hills have received small changes to the 6-figure grid reference: these will have the current revision date but lack an entry in the Comments column.
1538 Ward Hill (Fair Isle, Shetlands): the height has been revised to 219m. The trig point is some way below the summit.
3687 Glan Fedwen: new hill surveyed as just short of Dewey status.
Ten-figure grid references have been supplied for another 125 hills, making 2354 in all.
No new lists or features were added, but there are a significant number of changes to the data.
This release corrected a couple of errors in v8.0. v8.1.1 (05/08/07) subsequently corrected a bug in the Excel version.
The Deweys have been overhauled. This was prompted by the discovery of some errors in v7 and a set of more accurate grid references on Simon Edwardes' site. The most significant changes are given below. We have corresponded with Rob Woodall and Simon Edwardes and regard the current data as the best we can do pending more GPS measurements and surveys.
Black Mountain is now deemed to be in Wales only in the Marilyn and Hewitts tables. As the hill is no longer double counted in the Marilyn country totals in the Microsoft Access version of the database, HOF members can report their year-end figures from the Totals table without adjustment.
The number of hills with 10-figure grid references has reached 1719, of which 289 have been surveyed. Continuing the practice we started in v7, we have revised the 6-figure grid references to align with the new 10-figure GRs after correcting for the systematic error in the Garmin measurement (see Database Notes).
A new field gives hyperlinks to a 1:25000 map on OS Get-a-map.
In the Access version of the database, query 49 returns a list of unclimbed hills in any region. You will be prompted for the Section number. Note that if you omit the subsection letter, the query will return all sections commencing with that number, e.g. entering "1" will return not just 1A-1E but also 10A-10D etc.
The Deweys (hills in England, Wales and Isle of Man in the range 500-609m with at least 30m of ascent on all sides) have been added.
New fields record summit observations and surveys. 154 hills have been surveyed using levelling instruments.
Birks Fell (35B) has been promoted to a Hewitt and Nuttall. It replaces the Marilyn, Horse Head Moor.
A new Marilyn Twin Peak, Beinn Tharsuinn - Sidhean a'Choin Bhain (15B) has been added. It is also a twin Graham.
The number of 10-figure Grid References has reached 1553. 6-figure GRs have been overhauled to align with the 10-figure GRs.
The height of Knight's Peak has been increased to 915m and Beinn a'Ghlo - Carn nan Gabhar (6B) reduced to 1121m.
A new SubMarilyn has been added. This is hill 3336, Beinn Ceannabeinne (16B).
The number of 10-figure Grid References has grown to 1278, though 541 of these are from the Ordnance Survey trig point database. A new field has been added to identify the feature to which the 10 figure GR refers.
Two Deleted Munro Tops have been relocated and minor corrections applied to a handful of hills.
A new field has been added for 10 Figure Grid References. All data are from ground observations and are given to the nearest 5 metres. The database includes measurements for over 550 hills.
Two new Marilyns (one a promotion, the other a new hill) and a new English Nuttall have been added. See hills 140, 3320 and 3321.
Wainwright Outlying Fells have been completely overhauled. 14 new hills have been added, including the 12 nameless summits, and numerous changes made to grid references and heights. See the Database Notes for details. All hills in this list have been given the latest revision date irrespective of changes.
Correction to four entries in the Revision and Comments fields, and to the URL linking to this page in the Forms table.
The most significant change to the data is the addition of a new Marilyn Twin Peak, also a Twin Graham. This is hill 3319, Meall nan Damh (Section 12A). It is joined on 673m with hill 914, Carn na Coinnich, which remains the Marilyn by virtue of its trig pillar. There are minor changes to a further 20 hills involving a mixture of height changes, relocations and names. The hills are dated 28/01/04 in the Revision field; Query 44 in the Access version will bring them up.
The Streetmap field has been added to Queries 1-47 of the Access version. The URL has been modified to mirror a recent change in the site. It is now necessary to click on the grey arrows below and to the right of the map to bring up the 1:50000 OS map. For further information see the Database Notes.
Minor revision to correct errors in six hills.
Earlier releasesv3.0 27/01/2002 Minor revisions; additional queries and totals report in Access version
v2.1 21/11/2001 Minor revisions
v2.0 28/10/2001 Revised and improved
v1.0 13/09/2001 Draft for comment
If you are upgrading from v15.2 or earlier, be aware that a few hills where the summit location differs between lists, e.g. Burnhope Seat, have been split into two separate hills. Review the hills listed under Splits in the revision history for v14 onwards to see whether they affect your bags.
If you are upgrading from v11.2–v11.6 and have climbed Slieve Donard, transfer your record from hill 5617 to 20016
If you are upgrading from v10.2 or earlier and have climbed High Stile (34B) or Top o'Selside (34D), you may need to manually alter your records as these hills were split into two in v11. In addition, any record for hill 2304 (formerly Hangingstone Hill) should be transferred to 1846 Cairn Hill West Top (28B) as this hill number has been reused. You are also advised to check the revision history for relocations in case you have not bagged the true summit!
