Geology and urban analysis of Gua Musang city by using GIS

Geological study in Gua Musang City covers lithology, geological composition, stratigraphy geomorphology and petrography. The study objective is to generate the 1:30000 Geological Map of Gua Musang City, to create flood hazard map for Gua Musang City, to produce safety map for Gua Musang City. The fieldwork and laboratory analyses have been carried out in this research. Aspects included in fieldwork were lithological analysis for all unit stones, geomorphology and structural geology discovered. Petrography analysis was conducted during this study using the samples taken from the fieldwork. The rock unit found in the study area is granite, limestone, marble, shale, slate, mylonite, and phyllite. Flood hazard is very dangerous to urban area. Looking back to the big Yellow Flood of 2014, plenty of losses was counted and injury was beyond counting. Therefore, a safety map was supposed to be produced to guide the responsible parties to have better exposure about flood hazard. Citizens should be able to be alerted by the authority. A safety map will highlight about a safer choices for urbanization, to avoid the flood hazard. Thus, the fatality can be reduced greatly
