You are asking for the opposite of claustrophobia which people mistakenly think is agoraphobia which translates, "fear of the marketplace" but it really means that the person is afraid of having a panic attack or being trapped in an embarrassing situation without any escape. I don't believe there is an actual word to describe what the opposite of claustrophobia is. (I googled it and came up with chasmophila which supposedly ment the love of small places but ended up being a fake word)
Although many people would say it is Agoraphobia I don't think it is. Agoraphobia is the fear of public places, not wide open ones. Both phobias can be experienced in some of the same places.
Whatever the REAL word is for fear of wide open spaces is the opposite of claustrophobia.
As far as I know, there is not one.
