In this paper we define a class of Boolean and generalized Boolean functions defined on F_2^n with values in Z_q (mostly, we consider q=2^k), which we call landscape functions (whose class containing generalized bent, semibent, and plateaued) and find their complete characterization in terms of their components. In particular, we show that the previously published characterizations of generalized bent and plateaued Boolean functions are in fact particular cases of this more general setting.
