The Catalogs and Surveys Branch of the Space Telescope Science Institute, in collaboration with the Osservatorio Astronomico di Torino, the GEMINI project and ESA, is constructing a second generation Guide Star Catalogue (GSC-II) of astronomical objects to support the operations of current and future ground and space based telescopes. The second generation sky survey plates (POSS-II and SES) are being digitized at STScI, which when combined with the first epoch plates will allow us to produce a catalogue containing positions, proper motions, magnitudes and colurs to at least 18th magnitude for operational purposes. In addition to constructing such a catalogue, STScI is also compressing the second generation plate images using the same technique used for the DSS-I and is making the scan data available to the community in advance of a more general data distribution on CD/DVD. In this presentation we report on the status of the plate digitization, compression and plate processing. A separate contribution will describe the unique database aspects of this project.
