PAPA SYSTEM TO EXTRACT A DIGITAL LAND LIFT MODEL DISCOVERED FROM A PLURALITY OF GROSS TOPOGRAPHIC POINTS. A method (300) for extracting a digital elevation model from a plurality of raw topographic points representing a plurality of frames representing a plurality of perspectives of a multidimensional object comprising a surface and obstructions above the surface comprises steps or actions of: finding surface 304 by filtering data points produced by obstructions above the surface to provide a plurality of surface data representing the surface; and filtering surface data points 306 with a competitive filter to provide a multidimensional surface shell of digital elevation model data points. The retro described method may also be performed by a specialized or programmable information processing system (200) or as a set of instructions in a computer readable medium, such as CD ROM or DVD, or the like.
