In the talk, I will study minimal real valuations of the plane projective and Newton-Okounkov bodies of exceptional curve valuations of the plane projective too. I will explain how non-positive at infinity divisorial valuations help to this study. I will also give some details on the extension of the above objects by considering valuations of Hirzebruch surfaces instead of the projective plane.
