Explorer yet to go west, south and as far as northeast (11)

I believe the answer is:
livingstone
'explorer' is the definition.
(I've seen this before)
'to go west south and as far as northeast' is the wordplay.
'to go west south' becomes 'livings' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' means one lot of letters go next to another.
'as far as' becomes 'to'.
'northeast' becomes 'NE' (abbreviation).
'livings'+'to'+'ne'='LIVINGSTONE'
'yet' is the link.
Can you help me to learn more?
(Other definitions for livingstone that I've seen before include "one found by Stanley" , "one found in Africa" , "Scottish explorer and missionary" , "Presumed doctor" , "person presumably a doctor?" .)
