Description :
This paper reports on the use of a Geographical Information Systems (GIS) database, compiled primarily from existing digital maps and aerial photographs, to describe the physical characteristics of landslides and the statistical relations of landslide frequency with the physical parameters contibuting to the initiation of landslides on Lantau Island in Hong Kong. This GIS database is then used to obtain a logistic regression model for predicting slope instability. This model is then imported back into the GIS to produce a map of predicted slope instability.
