LT is a digital light table that provides dynamic visualization and coordinated data collection for large-format stereo and monoscopic images. It enables the user to zoom and continuously roam over the displayed images to acquire points, grids, break lines, drain lines, and to overlay vector GIS information that is registered to the imagery. This vector data can also be displayed in stereo so that it appears in 3-D to lie on the surface of the terrain.LT has been used as a soft-copy mapping tool for various types of stereo imagery including aerial photography, SPOT, and synthetic aperture radar.
