How to use this map
Trig points
Each red triangle marks a trig pillar. Tap or click one to see its grid reference, trig ID and coordinates.
Reference circle
Zoom in close enough and a 250m circle appears around each trig — a quick visual reference for the area immediately around it.
WAB grid
The Ordnance Survey 10km grid (or the Irish Grid over Ireland). It only draws once you're zoomed in far enough to read it clearly.
UKBOTA
Toggles UK bunkers on the map. Zoom in close enough and a 1000m circle appears around each one, same as the trig reference circle.
Summits
Toggles SOTA summits on the map, shown as green triangles with olive-drab clusters when zoomed out.
Lighthouses
Toggles UK lighthouses on the map, shown as amber towers with blue clusters when zoomed out.
My location
Shows your current position on the map. Your browser will ask permission first — nothing is shared until you allow it.
Search
Search by grid square (e.g. TA32) or reference (trig ID, e.g. TP5437, or — once toggled on — a bunker, summit, or lighthouse reference/name too). A single match zooms straight to it and opens its details.
Numbered clusters
A numbered circle stands in for several nearby trigs. Click it, or zoom in, to break it apart into individual points.
SOTA summits, UKBOTA bunkers, and UK Lighthouses can also be toggled on but are off by default
