Option 2: Enter a gridref or lat, lng coordinates
latitude and longitude
Latitude and longitude are in decimal format with a max of 15 digit percision. Manually entering coordinates will cause the grid ref to automatically update.
Grid reference
The grid reference accepts UK or Irish grid references to a 5 digit easting/northing percision. Enter the grid ref and click on the button to the right to apply the gridref.
This causes lat,lng coordinates to automatically update as well.
Note: any updates here also re-centres the map marker [option 1] on the new coordinates.
