We study generalized parton distributions in the impact parameter representation, including the case of nonzero skewness $\xi$. Using Lorentz invariance, and expressing parton distributions in terms of impact parameter dependent wave functions, we investigate in which way they simultaneously describe longitudinal and transverse structure of a fast moving hadron. We compare this information with the one in elastic form factors, in ordinary and in kT-dependent parton distributions.
