We present an idea how to provide a computational semantics for path relations like along, through or around. Since the shape of the trajectory of a path relation is bounded by the shapes of the reference objects, an extended notion of geometrical approximations is suggested to take into account detailed shape information. Furthermore we discuss a set of features that are the building blocks of the semantics of path relations. In particular geometric features of several reference objects are evaluated to generate a single integrated reference object. As an example a procedural description of the semantics for along is presented.
