Map of the southern uplands (4)

I believe the answer is:

plan

'map' is the definition.
(eg the plans for a building)

'of the southern uplands' is the wordplay.
'of' indicates the answer is hidden within the clue.
'PLAN' is hidden in the letters of 'southern uplands'.

(Other definitions for plan that I've seen before include "Scale drawing; scheme" , "Devise a strategy" , "Stratagem" , "Agenda" , "Diagram; design" .)

I've seen this clue in the Evening Standard.
