Abstract
Derivations of informative maps such as hazard and risk maps are needed in development planning and hazard management. Geospatial technology provides a platform that is capable of accurately and efficiently processing multi-faceted land-based information ranging from topography, geology, geotechnical parameters, land-use and socio-economic to various elements that might be impacted. This paper highlights several examples of research projects where imaging and geographical information systems are extensively utilized in mapping, data managing, analysing, modeling and integrations that SEADPRI experienced. Integrated multi-hazard assessment using GIS was carried out to map and assess discreet and combined hazard risks of landslide, subsidence and flood in the Klang Valley administrative region. Large-Scale Landslides “Integrated Research” for Kundasang Landslide Complex in a town located on several active landslides of the size of half kilometer. Base map generation and value-adding through aerial-photographs and satellite images enhancement and incorporating data from geology, surface geodynamic mapping, geotechnical parameters etc. Enhancement of slope stability assessment for site planning for development of Datai Beach, Langkawi, with simple landform modeling and 3D visualization coupled with geology and structural geology. It complemented fundamental geology’s rock discontinuities and environmental assessment. GIS could also emulate scenario and simulate real-world model. The possibilities of hazards and conditional change of environmental parameters were used to create modeling for tsunami and flood.
