You make a good point, but as Tarmach is based in Guildford, I'd just like to add the caveat that lots of landmarks can look quite similar in SE UK .... for example there are many infringements of the Stansted zone every year and the UK CAA report that the lack of features in the locale is a major factor. The congested nature of the airspace in the SE of England makes this a pain for pilots.
So whilst your point is very well made, it is necessary to be very careful in identing the landmarks.
UK AOPA put together a radio nav course syllabus for VFR pilots some years ago to assist in this area.
