LIDAR DATA USE FOR THE GEOGRAPHICAL DELIMITATION OF FIRE RISK IN WILDLAND-URBAN INTERFACE (WUI) APPLIED TO GUISANDO (AVILA, SPAIN)

The term Wildland-Urban interface (WUI) is used in order to refer to areas where forest and urban spaces are combined, resulting in new territorial dynamics, due to the changes of the cultural perception of the space which is inhabited. Forest fires are an important and growing risk to be faced in these new territories, where the management is more difficult, which generates socioeconomic and environmental repercussions. In this work the delimitation of Wildland-Urban interface has been developed. It is the first step to create a suitable management and prevention of forest fires. All this process was carried out using a geographical reference Guisando, located in the Tietar Valley (Avila, Spain). The results show the prospective of the uses of LIDAR data, through the Geographic Information System (GIS) technologies with free and open source software. Moreover, they are valid to manage and delimit spaces at risk.
