Okay so, if we're looking at a tile from a to c with b in the middle,
we have several scenarios:
1. a>b - - I can see everything, b does not hide c
2. a==b
2.1 a==b==0, all flat ground, no hiding
2.2 a>0, b>=c - b hides c from view (say I am in a forest/jungle and b is a forest/jungle, or hill)
2.3 a>0, c>b - c is tall enough I can see it over b!
2.1 c>b - c is tall enough I can see it over b!
2.2 b blocks view from same-elevation tiles - hides c
2.3 none of the above - I can see c
3. a<b
3.1 b>=c - b hides c
3.2 b<c - c is tall enough I can see it over b!
This can all be summed up as "I can see c if a>b || c>b || b==0 "
This can all be summed up as "I can see c if a>b || c>b || (a==b && b !blocks same-elevation view)"
