10-year Extended LPM Project, Phase 3, Package A - Stability Studies of Private Slopes in Eastern and Southern Districts of Hong Kong Island – Investigation, CE 61/2001

Carried out digital photogrammetry modelling by using stereoscopic aerial photos of different years to derive various Digital Elevation Models (DEM) of the study area in order to compare change of land profile and hence to precisely measure the variation of field thickness volume of the man-made slope. The photogrammetric system that was used is VirtuoZo
