The wildland-urban interface map of Catalonia [Research data]
MetadataShow full item record
The wildland-urban interface (WUI) is the area where residential structures intermingle with hazardous vegetation and where most housing losses and human fatalities are concentrated. We provide a WUI map of Catalonia, a fire-prone area in northeast Spain where destructive fires caused substantial economic
losses in previous decades. Individual housing location, structure density and the vegetation type were used to map the different WUI classes using a geographical information system. WUI areas were concentrated in the coastal belt where suburban sprawl has ocurred nearby or within unmanaged forests. This geospatial information data provides an approximation of potential loss given a fire and provides valuable information to assist landscape and urban planning in the region.
