We describe the design and applications of a software system for analyzing the digital scans of the Second Palomar Observatory Sky Survey (POSS-II). The system (SKICAT) integrates new and existing packages for performing the full spectrum of tasks from raw pixel processing, to object classification, to the photometric matching of multiple Schmidt plates. The system also provides a variety of tools for interactively querying and analyzing the resulting object catalogs. Portions of SKICAT are directly applicable to digital sky surveys of the near future and large-format CCD imagery of today.
