Welcome to IMPReSS

IMPReSS (IMage PeRimeters of Sky Surveys) is a graphical interface to astronomical databases that presents the user with plane of the sky outlines or silhouettes of images obtained by space-based telescopes. Its purpose is to provide a visualization environment that finds and displays, in detail, mission footprints that lie within a user selected region of the sky. Searches can also be restricted by the observation date. Once the user has selected observations of interest, IMPReSS will aid in retrieving publicly available data by sending requests to data archive sites for detailed information, browse images, and data files.

There are two interfaces to IMPReSS:
