Introducing a Geospatial Based Infectious DiseaseInformation System (IDIS) in Malaysia as an innovative initiative to control the disease is essential due to local environmental risk factor and public health awareness. Malaria is one of the major disease concerns in rural areas, requiring an efficient system to manage the disease. Most of the current disease information systems used by the local health authorities are non-spatial based method, which has not consisted of spatial features and functions. This study adapted the Geographical Information System (GIS) technology to develop an integrated Geospatial-Based Malaria Information System. The proposed system could enhance malaria surveillance programme in Malaysia to achieve zero malaria cases by 2015.

Flooding is an unavoidable disaster. However, the impact and the risk to be affected by flooding can be reduced. Recently, floodplain modeling known as new method applied in river engineering modeling and has been used by many researchers in determining flood prone area, The objective of this research is to explore the integration of Geographic Information System (GIS) and hydraulic simulation model, Hydrologic Engineering Centers River Analysis System (HEC RAS) in determining the steady flow simulation model and possibility flooding areas for Bandar Segamat Johor. The methodology of this research is divided into 5 stages, include study area identification, data acquisition, data processing (spatial data generation), data processing (simulation), result and analysis. In this research, steady flow for Segamat River and Kapeh River was simulated. Flood map was produced by integrating both GIS and HEC RAS analysis. The results suggest that the integration of HEC RAS and GIS analysis can lead to a better visualization for flood mapping to be used by the society and considered to be helpful for future development.
