A DEM of 10m cell size was then built running appropriate programs from the first level match - see Fig. 5 
(the whiter the pixel value the higher the height of the pixel). At the end a small ortho-rectified image was 
produced. The result is illustrated in Fig. 6: a three dimensional perspective of the orthoimage draped over the 
DEM. The voids in the figures are areas where the point density per block is not sufficient to produce the DEM.
