Golf design — golf course architecture — is really unique among "art" forms. I'm never convinced it is pure art. Rather, art and science.
The closest profession I can ever think of is the creator of games at Milton Bradley. Here a person sits and continually deals with intrigue, mystery and fun. Her or she comes to work and uses technology, science and wit to create a game board and a set of choices and luck which forms a game. Sort of like GCA.

Landscape Architecture is:
Primarily a fine art, and as such, its most important function is to create and maintain beauty in the surroundings of human habitations, and in the broader natural scenery of the country; but it is also concerned with promoting the comfort, convenience and health of urban populations which urgently need to have their hurrying workday lives refreshed and calmed by the beautiful and reposeful sights and sounds which Nature, aided by the Landscape Art, can abundantly provide (Origin: Penn State’s Dr. John R. Braken, as recalled by Arthur Jack Snyder, a student of Braken.)
