Estimating Fuel Loads and Structural Characteristics of Shrub Communities by Using Terrestrial Laser Scanning

Autor: Cecilia Alonso-Rego, Stéfano Arellano-Pérez, Carlos Cabo, Celestino Ordoñez, Juan Gabriel Álvarez-González, Ramón Alberto Díaz-Varela, Ana Daría Ruiz-González

Publikováno v: Remote Sensing, Vol 12, Iss 22, p 3704 (2020)

Forest fuel loads and structural characteristics strongly affect fire behavior, regulating the rate of spread, fireline intensity, and flame length. Accurate fuel characterization, including disaggregation of the fuel load by size classes, is therefo

Potential of Sentinel-2A Data to Model Surface and Canopy Fuel Characteristics in Relation to Crown Fire Hazard

Autor: Stéfano Arellano-Pérez, Fernando Castedo-Dorado, Carlos Antonio López-Sánchez, Eduardo González-Ferreiro, Zhiqiang Yang, Ramón Alberto Díaz-Varela, Juan Gabriel Álvarez-González, José Antonio Vega, Ana Daría Ruiz-González

Publikováno v: Remote Sensing, Vol 10, Iss 10, p 1645 (2018)

Background: Crown fires are often intense and fast spreading and hence can have serious impacts on soil, vegetation, and wildlife habitats. Fire managers try to prevent the initiation and spread of crown fires in forested landscapes through fuel mana

Combining multispectral and texture imagery features to assess health condition in priority riparian forests by means of unmanned aerial systems

Autor: Patricia María Rodríguez-González, Juan Guerra-Hernández, Ramón Alberto Díaz-Varela, Juan Gabriel Álvarez-González

Expansion of damaging pests and pathogens is a reality which, together with rapid global change, is arguably the greatest contemporaneous challenge to sustainable forestry and the continuing function of forest ecosystems. Alnus glutinosa (black alder
