- In [2] the pseudo-metric ${\rm dist}^{\rm max}_{\rm min}$ on compact subsets $A$ and $B$ of a topological space generated from arbitrary metric space is defined. Using this notion we define the Hausdorff distance (see e.g. [6]) of $A$ and $B$ as a maximum of the two pseudo-distances: from $A$ to $B$ and from $B$ to $A$. We justify its distance properties. At the end we define some special notions which enable to apply the Hausdorff distance operator ${\rm ``HausDist"}$ to the subsets of the Euclidean topological space~$\calE^n_T.$
