Map-making (11)
I believe the answer is:
cartography
I believe this is a double definition.
'map' is the first definition.
(thesaurus)
'making' is the second definition.
(I know that cartography is a type of making)
(Other definitions for cartography that I've seen before include "Map making" , "Science of drawing maps" , "making plans" , "Map-making" .)
