A forest fire risk assessment using NOAA AVHRR images in the Valencia area, eastern Spain

Abstract: The risk of widespread forest ® re has been assessed from information supplied by the AVHRR sensor onboard NOAA satellites, for the area of the Autonomous Community of Valencia in eastern Spain, where several major forest ® res occurred in the summer of 1994. The burnt surface data were obtained through unsupervised classi® cation of the spectral information of the forest areas, ® rst, from a date previous to the forest ® re; and second, from a date following the ® re. The methodology for the forest ® re risk … Show more

“…Fire occurrence is influenced by biophysical as well as human factors. How the frequency and distribution of fires, as well as their ignition agents, vary with climatic and meteorological conditions (amount and seasonal distribution of precipitation or relative humidity), vegetation type and water status or land use has been documented in the literature (Andreae, 1992; Cahoon et al ., 1992; Larsen, 1996; Gonzalez‐Alonso et al ., 1997; Kitzberger & Veblen, 1997; Dwyer et al ., 2000; França & Setzer, 2001). Regarding human influences, palaeo‐records demonstrate that for more than 1 million years people have been altering the natural patterns of fire occurrence intensity and frequency (Levine, 1991; Andreae, 1992; Kitzberger & Veblen, 1997).…”

“…Attempts to assess wildfire risk in other parts of the world have typically been implemented as Geographic Information System-based overlays (Burgan and Hartford 1988, Chuvieco and Congalton 1989, Julio 1990, Chou et al 1993, Castro 1994, Salas and Chuvieco 1994, Carapella 1996, Gonzalez-Alonso et al 1997). However, we chose not to duplicate these methods for the Upper Midwest, as such studies usually are performed at only a single scale using subjective assessment of the influence of local fire factors.…”

“…El sensor AVHRR (Avanced Very Hight Resolution Radiometer) a bordo del satélite NOAA (Nacional Oceanic and Atmospheric Administration) ha sido ampliamente utilizado en el estudio de los incendios forestales (Barbosa et al, 1999;Pereira et al, 1999;Fernández et al, 1997, González-Alonso et al 1996, González-Alonso et al, 1997, debido a su cobertura espacial, espectral y temporal, sobre todo cuando se trabaja con grandes extensiones (Illera et al, 1995). Actualmente nuevos sensores como el MODIS (Moderate Resolution Imaging Spectroradiometer) están abriendo una nueva era en la estimación de superficies quemadas debido a las mejoras espaciales, espectrales y temporales que presentan dichos sensores , Merino-deMiguel et al, 2005.…”
