General geology and determination of potential limestone geohazard by using gis at Kampung Gunong Batu Melintang, Jeli , Kelantan

This study is about the general geology and determination of potential limestone geohazard by using geographic information system at Kg.Gunong Batu Melintang in Jeli, Kelantan. Geographic information system is a system designed to capture, store, manipulate, analyze, manage, and present all kinds of spatial or geographic data. The study area is located between coordinates N 5˚42'16.65 "to N 5˚45'1.22" and E 101˚43'14.32 "to E 101˚ 46'1.70''E. The aim of this study is to produce and improve an existing geological map of the study area, identify the limestone karst condition by using geographic information system and to produce potential of limestone geohazard map for the study area. For the determination of potential limestone geohazard, the raster multi-overlay analysis method was choosed. The analysis of raster data was performed by using the weightage corresponding to the specifications assessment. At the end of the study, the potential of limestone geohazard map of the study area was produced. Based on the GIS analysis interpretation, the potential of limestone geohazard in the study area is considered to give moderate hazard. The results of this study can contribute to the understanding of the geology of the study area, and may help in the development of the future.
