Filters for Waypoints & Bagging Lists
There are far too many waypoints, trigpoints, tumps and other hills in the databases to display them all at once. So at least one filter must be used on any display. There are a number of different ways of filtering the content available and some can be used in conjunction.
(N.B. Some filter conjunctions will always give a null result; e.g. there are no Wainwrights in Scotland or no Corbetts in Wales etc…)
Filtering by Area
Hills & Waypoints can be filtered by area.
Areas can be by country e.g. www.haroldstreet.org.uk/waypoints/download/?area=england
by ‘Marilyn Area’ numbers 1 to 57 (with sub-areas) e.g. www.haroldstreet.org.uk/waypoints/download/?area=34 or
by Ordnance Survey Grid Reference areas “HP” to “TV” e.g. www.haroldstreet.org.uk/waypoints/download/?area=NY
Or any rectangular area between two grid references like this…
which gives all the hills between NY123456 and NY456789. (Two, Four and eight figure grid references also work – see here for more details).
the full list of “areas” available is given at; www.haroldstreet.org.uk/waypoints/areas.php
In the left menu bar:
- Area numbers in orange/red have similar hills and clicking will take you to those hills in that area with the same filters applied.
- Area numbers in grey have no hills of the same type, and so clicking will take you to ALL hills in those areas.
Areas can also be excluded for example Marilyns excluding Irish:
(Only filtering by OS area is available to Trigpoints, unless they are also categorized by a hill type.)
Filtering by Hill type
Most Waypoints and Hills can be filtered by their mountain list classifications. E.g.
Trigpoints on Hills (but not all trigpoints, only those on significant hills)
For the full list of available types see… www.haroldstreet.org.uk/waypoints/
Filtering by Bagged Status
If you are a member using the online tick lists you can use the “status=” URL filter show either all the hills you’ve climbed, or not climbed, in any particular list or area e.g.
or Unclimbed Wainwrights www.haroldstreet.org.uk/waypoints/download/?list=wainwrights&status=unclimbed
This can be used with the “user=” filter to see what a sepecific member has bagged in a particular area or list.
Filtering by Height
You can use the “height=” URL filter to filter hills by minimum height in meters. For example;
UK 1000m Mountains www.haroldstreet.org.uk/waypoints/download/?height=1000
You can use this directly in combination with “max=” URL filter to narrow the filter to a maximum height in meters. For example;
“English Corbetts” are English Marilyns between 762m(2500ft) and 913m(2999ft) www.haroldstreet.org.uk/waypoints/download/?list=marilyns&height=762&max=913&area=england
“Welsh Corbetts” are Welsh Marilyns between 762m(2500ft) and 913m(2999ft) www.haroldstreet.org.uk/waypoints/download/?list=marilyns&height=762&max=913&area=wales
“Irish Corbetts” are Irish Marilyns between 762m(2500ft) and 913m(2999ft)
We have also added the filter height=prominence to allow you to filter the highest summit of any island.
Filtering by Prominence
It is also possible to filter by prominence or re-ascent (in meters) using “prominence=” For example;
The Really Big Hills of UK (P609m) a list of British and Irish hills with at least 2000 feet of prominence. www.haroldstreet.org.uk/waypoints/download/?prominence=609
Tumps (P30m) a list of the hills with at least 30m of prominence, including lesser tumps of height <490m www.haroldstreet.org.uk/waypoints/download/?prominence=30
I quite like this one for demonstrating some really significant hills with 3000ft prominence www.haroldstreet.org.uk/waypoints/download/?prominence=912
It is also possible to set an upper limit so this for example will give all the UK Sub-Tumps with seperation between 1 and 29.99m
We have also added the filter prominence=height to allow you to filter the highest summit of any island.
Find by Location
We’ve added a new “find by location” url filter to our Trigpoint & Hill pages. For example the page… www.haroldstreet.org.uk/waypoints/download/?g=NN166712 will look up the nearest hill (or failing that the nearest trigpoint) within a 20km square of the grid reference provided by the ?g= value
If you only want trigpoints then the same filter works on the trig-bagging pages like this… www.haroldstreet.org.uk/trigpoints/trig-bagging.php?g=NN166712
Both pages will redirect to Ben Nevis which is a Hill and a trigpoint at NN166712
There are also some interesting options for adding and subtracting lists from each other detailed here…
Many of these filters can be used in combination with each other.
