Contour lines generated from automatic image correlation in a densely built-up area. The contours generated by tic 
image correlation (thin lines, 50 cm interval) are compared with operator drawn contour lines (thick lines, 1 m | ofi 
interval); picture scale 1:5000, flying height 1500 m. For technical reasons, the two sets of contour lines are displaced co 
in height by 50 cm. | He
