Summary
The Stereo Zoom Transfer Scope is used to create ASCII file "coverages" by digitizing directly from stereo pairs of interpreted aerial photos. This is accomplished by removing all parallax error along the flight line and referencing the photos to the Earth's surface with control points acquired using differentially corrected Global Positioning System data. The ASCII files are then converted to an ARC/INFO format, where they can be generated into a digital coverage, edited, labeled, and archived.
