A study carried out in Spain on the location of fire stations and their territorial coverage points out deficiencies in relation to care within a reasonable time frame. This article analyzes the use of Geographic Information Systems (GIS) to determine the territorial coverage and population served by fire services in a specific response time. This road response time is based on the response from other countries. The study compares the information obtained in an analytical manner from the population and surface area served in Spain by firefighters, with the data obtained through the use of GIS tools, concluding that the population and surface area left unattended is higher than initially estimated. The article describes and analyzes an alternative solution to reinforce the current network of fire stations with fire stations with localised professional staff capable of being deployed in underserved areas, mainly in rural areas.
