Abstract We study the relationship between the concept of a continuous ellipsoid Θ cover of R n , which was introduced by Dahmen, Dekel, and Petrushev [7] , [8] , [11] , and the space of homogeneous type induced by Θ. We characterize the class of quasi-distances on R n (up to equivalence) which correspond to continuous ellipsoid covers. This places firmly continuous ellipsoid covers as a subclass of spaces of homogeneous type on R n satisfying quasi-convexity and 1-Ahlfors-regularity.
