Ordnance Survey Proposed Changes to Latitude and Longitude Representation on Paper Maps



Ordnance Survey (OS) is considering changing how Latitude and Longitude are represented on their paper maps.  I’ve filled in their questionnaire this morning and it takes less than two minutes.  Well worth doing as it gives the OS feedback from the hill bagging community / customers and general public.

The below was recently received from the OS.


A brief consultation and questionnaire from Ordnance Survey on proposed changes to the lat/long overlay on OS maps. Do please distribute as you see fit.

Quoting from the questionnaire ‘Please note this would not be a change in the base map datum, which remains the Transverse Mercator Projection on the Airy 1830 ellipsoid, but a change in the datum of the latitude/longitude graticule overlay only.’


Proposed changes to latitude and longitude representation on paper maps – tell us your thoughts

Ordnance Survey GB is considering changing the overlay showing latitude and longitude markers on Ordnance Survey paper maps. This would mean moving towards the overlay showing latitude and longitude used on GPS devices, to help bring digital navigation devices and paper maps closer together and work more in harmony. We believe this would have little impact on the majority of users of our paper maps; however, we would like your opinions on this change to ensure we fully consider all options and impacts before we make a final decision.

We’d like you to read the information below, and, if you would like to share your thoughts on how this would affect you, complete our short survey by Friday 3 October.
