Study excursion outline (7)

I believe the answer is:

contour

'outline' is the definition.
(I know that contour is a more specific form of the action outline)

'study excursion' is the wordplay.
'study' becomes 'con' (con can informally mean to study).
'excursion' becomes 'tour' (I've seen this before).
'con'+'tour'='CONTOUR'

(Other definitions for contour that I've seen before include "Feature on map" , "Defining line" , "Outline, shape" , "Outline (of land)" , "Outline, profile" .)

I've seen this clue in The Globe and Mail.
