DPS - a digital photogrammetric system for producing digital elevation models and orthophotos by means of linear array scanner imagery.

A new digital procedure for generating and processing scanner images is presented. The terrain is scanned by an opto-electronic three-line scan camera. Each sensor array produces an image strip of the covered terrain according to the push broom principle. The coordinates of all image points and a few control points are inserted into a least-squares adjustment for computing the orientation parameters of the camera along its entire flight course and the coordinates of the points of the DEM. -from Authors
