Abstract

Three dimensional position data of ground objects watched on a landsliding area can effectively and safely be obtained by aerial photogrammetry. These data acquired by several flights of different time are used to the least square algorithm that is constructed for presumption of the geometric shape of underground slide surface. This paper newly introduced two techniques into the analytic procedure. They are 1) estimation of the reliability of tracking points and boundary conditions, 2) connection condition of many different shapes of sliding group. Effects of these techniques are verified by numerical examples applied to the actual landslide areas having complicated shape of underground slide surface.
