Using air-photographs, it is useful to measure the tree height and stand density in forest. In this paper, the three-dimensional mapping procedure, which is automatic contouring with a personal computer and scanner, is developed, and tested with real photographic data in forest. As a result, the proposed procedure is available to measure the tree height, if the top and bottom of tree can be identified on the air-photographs, and the estimated stand density almost agrees with the measured one, if there is coniferous forest where the tree has a single canopy top.
