We use the -Ponomarev-system , where is a locally separable metric space, to give a consistent method to construct a -mapping (compact mapping) with covering-properties from a locally separable metric space onto a space . As applications of these results, we systematically get characterizations of certain -images (compact images) of locally separable metric spaces.

The main purpose of this paper is to establish general conditions under which -spaces are compact-covering images of metric spaces by using the concept of -covers. We generalize a series of results on compact-covering open images and sequence-covering quotient images of metric spaces, and correct some mapping characterizations of -metrizable spaces by compact-covering -maps and -maps.
