It's right there on the map! (4)
I believe the answer is:
east
'it's right there on the map' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for east that I've seen before include "Towards the dawn" , "To right if facing North" , "Direction of the Orient" , "Compass direction" , "Bearing of 90 degrees" .)
