Having a fire is one of the deadly hazards and causes of property loss in the Philippines, fire hydrants are the critical main source of sufficient water supply for firefighting especially in urban fires. Thus, for efficient and effective fire emergency response, firefighters and locals should know where are the locations of the closest fire hydrants when there is a fire emergency. With this, the Viscan YouthMappers did a project of mapping fire hydrants to serve as baseline data for fire emergency response in Leyte Province, Philippines.
