Given a non-degenerate Peano continuum $X$, a dimension function $D:2^X_*\to[0,\infty]$ defined on the family $2^X_*$ of compact subsets of $X$, and a subset $\Gamma\subset[0,\infty)$, we recognize the topological structure of the system $(2^X,\D_{ \le\gamma}(X))_{ \alpha\in\Gamma}$, where $2^X$ is the hyperspace of non-empty compact subsets of $X$ and $D_{ \le\gamma}(X)$ is the subspace of $2^X$, consisting of non-empty compact subsets $K\subset X$ with $D(K)\le\gamma$.
