The concept of a $\sigma$-locally countable mapping is used for establishing relations between metric spaces and spaces with $\sigma$-locally countable $sn$-networks ($cs^*$-networks, weak bases).
Keywords: $cs^*$-network, $sn$-network, weak base, $\sigma$-locally countable mapping, sequence-covering mapping.
