Naming of Waypoints

Each Waypoint requires a unique name in 6 characters this inevitably leads to a much coded abbreviation. I try to use the height in the name as this can be seen on the map too. The full name of each peak is stored in the comment for each Waypoint.

Wainwrights

For each Wainwright the code starts with its height in metres (3 characters) then "W" followed by a number between 1 & 8 representing the volume of the Wainwright book, this is followed by "H" for Hewitt, "M" for Marilyn, "B" is its Both or "N" if its neither.

e.g. Scafell Pike is "978W4B" 978m high, Wainwright Volume 4 and Both a Marilyn and a Hewitt.

Marilyns, Hewitts and Nuttalls

Each Marilyn starts "M", Hewitt "H" and Nuttall "N"; followed by an "E" if its in England, This is then followed by its height in metres and a hyphen . Where two or more peaks in the same area have the same height, then the hyphen character is replaced by "a", "b" "c" etc...

e.g. Yr Wyddfa (aka Snowdon), 1085m high; is "M1085-", "H1085-", or "N1085-" in each list.

Scottish Hills & Mountains:
Munros, Tops, Murdos, Corbetts, Grahams and Donalds

All the Scottish Hills & Mountains are prefixed by letters "A" to "Z" denoting region see map below, followed by its height in metres (4 digits) then by a hyphen. Where two or more peaks in the same area have the same height, then the hyphen character is replaced by "a", "b" "c" etc.... The first letter of the comment information denotes the hill's classification; "M" for Munro, "T" for Top, "C" for Corbett, "G" for Graham, "D" for Donald.

e.g. Ben Nevis is "D1344-"

Disclaimer

It is very important that any walkers do not rely on their GPS as their only means of navigation - that's a great way to look really stupid when your battery goes down, or you walk off a cliff in poor visibility. These machines are no replacement for map, compass, & the knowledge of how to use them, nor for common sense regarding weather, terrain and appropriate clothing.

MOST grid references used are ONLY accurate to 6 figures and therefore refer to the SW corner of an AREA of 100m x 100m which contains the summit. This means that the Waypoint maybe up to 142m away from the summit and still be technically correct. There are over 20,000 grid references listed on this site, I've checked and revised them as well as i can but there may still be errors. Feedback on inaccuracies would be appreciated, but I don't wish to get into arguments about which peak may be the "proper" summit of anything.

I strongly recommend that all users of this information, check it against a map before going anywhere. I accept absolutely no responsibility for anything whatsoever which may arise from the use of this information.
