A system, method, and computer program product for efficiently mapping a pattern, such as a fingerprint, from a set of multiple impressions of portions of that pattern. The system may evaluate images of patterns taken from a series of multiple impressions and map the pattern from the image portions while providing the operator with realtime feedback of a status of the set of images. As each new image portion is evaluated, a display graphic or other indicator provides feedback when a new image portion is added to the reconstructed image, or when a new image portion is not added (such as it representing a duplicate). Other status indications may be provided, and when the indication is visual, a degraded resolution of the pattern map may be provided on the display graphic to improve security.
