Abstract
Peat swamp forest fire hazard area were identified and mapped by integrating GIS-grid based and Multi Criteria Analysis (MCA) to provided valuable information about the most likely areas to be affected by the fire in Pekan District at South of Pahang, Malaysia. Spatially weighted index model was implemented for developing fire hazard assessment model in this study. The fire-causing factors such as land use, road network, slope, aspect and elevation data was utilized in this application. The two mosaic Landsat TM scene was used to extract land use parameter of the study area. Triangle Irregular Network (TIN) was generated from digitized topographic map to produce slope risk map, aspect risk map and elevation risk map. Spatial analyst such as surface analysis, distance, proximity, and map calculator were applied to reclassify and overlay all grid hazard maps for producing a final peat swamp forest fire hazard map. For validating model, the actual fire occurrence map was compared with the fire hazard zone area that derived from the model. The limitation of this study is the model can be implemented only for specific area especially for Pekan Peat swamp forest, other criteria should be considered if the model will be implemented for another area. Even though the results showed that most of the actual fire spots are located in very high and high fire risk zone that derived from the model.
