Unfortunately. though being in what is, in my opinion, the best format, those coordinates are not the actual disposal points but are some point nearby. This can make the actual location of those points somewhat difficult.
That at Canterbury 51.26173, 1.10161 being the administration (or whatever) building whereas I know the location of the disposal point to be 51.26160, 1.10013 some 105 metres away and not in sight of the location specified. If anyone knows the actual location of the points, maybe they can amend the list of coords then I can reliably amend my personal database of locations.
