Development of GIS Based Landslide Hazard Assessment

The project was conducted to generate and integrate the development of spatial database
landslides potential hazard mapping database in determining the level of safety and
conscientious in earthwork analysis. Landslides constitute major geological hazard that
occurs widespread, causing extensive damages and casualties all over the world.
Expansion of urban and recreational development into unstable potential landslide area
increases the number of residential and commercial properties threatened by the risk of
landslides. Slope failure can cause fatality and property damage thus to avoid material
loss and human casualty, potential unstable areas are determined during the early stage of
project development planning. The study emphasized on mapping out the conceptual
overview of potential landslide hazard with further evaluation on the factors relevant to
the triggering sources ofthe hazard. Modules ofstudy on specific zone such as geological
parameters, environmental impact and growth of urban area were evaluated for the
database research input prior to the real hazard mapping generated by Geographic
Information System (GIS). These modules were further interpreted for possible
identification and classification ofpotentially unstable site illustrated as hazard map.
