The aim of this research is to evaluate the spatial risk factor for high incidence of Leptospirosis outbreak by using GIS application. This research also identifies the factor that increases incidence of Leptospirosis in Petaling district. Data involves in the research is Leptospirosis cases data from Selangor State Health Department Another data is digital base map of Petaling district from Department of Survey and Mapping. The factors used to determine Leptospirosis risk area namely land use, population and temperature data. The land use data is obtained from Town & Country Planning Department, population data is from Department of Statistics and temperature data is extracted from satellite image using Landsat 8 image. The determination of leptospirosis incidence is made by produce Leptospirosis distribution map (LDM). The LDM is produced using overlay method which is intersecting method and symbology. The identification of factors that increases the leptospirosis incidence is made by producing a Leptospirosis risk map (LRM). A LRM is produced using Getis-OrdGi* technique. The determination of risk area is based on several factors including land use and population factors. The used of GIS application to evaluate the health problem is one of the suitable methods compared with conventional method that made analysis based on the graphs and tables only.
