Improving the accuracy of our data

Hills

A fraction of the  hills database data on this site still uses 6 figure grid references (these are less accurate for GPS use.) Those that are are shown with their grid reference in italics with an asterisk like this NN635500*

If you wish to help improve the accuracy of these, members can do so by clicking the grid reference link, to go to the full ‘map view’ of the hill in question.

You should see a square icon around the hill’s top. This represents the area covered by the 6 figure grid reference. Hopefully an actual  spot height or a  cairn may be visible within this square.

If it is, you may ‘click’ the correct spot for the hill top, and then select the 2nd option “Refine waypoint GR here“. You should receive a confirmation that your new data has been accepted and the map will refresh with a target icon signifying the new waypoint location.

You might need to refresh any other windows you had open to ensure they are all also using the new data.

Your input will make things better for all our users.

Trigpoints

Whilst all our trigpoints have complete 10 figure grid references, sometimes they have been removed or destroyed.
If you find such a Trig, please add a comment to its page and report it as gone.

See this example…
‘TP0750′ SK464252  Bleak House Hill (93m) *

* Any trigpoints shown in grey italics in various lists have been reported missing or destroyed
