  In the study of aperiodic order via dynamical methods, topological entropy is
an important concept. In this paper, parts of the theory, like Bowen's formula
for fibre wise entropy or the independence of the definition from the choice of
a Van Hove sequence, are extended to actions of several non-discrete groups. To
establish these results, we will show that the Ornstein-Weiss lemma is valid
for all considered groups which appear in the study of cut and project schemes.
