Understanding the spatial and temporal trends of burned areas (BA) on a global scale offers a comprehensive view of the underlying mechanisms driving fire incidence and its influence on ecosystems and vegetation recovery patterns over extended periods. Such insights are invaluable for modeling fire emissions and the formulation of strategies for po...
The increasing availability of products generating burned area (BA) maps in recent years necessitates the creation of more accurate reference perimeters to validate these products and provide users with information about their accuracy. For this purpose, reference perimeters were created using Sentinel-2 images in Latin America and the Caribbean (L...
A preliminary version of a global automatic burned-area (BA) algorithm at medium spatial resolution was developed in Google Earth Engine (GEE), based on Landsat or Sentinel-2 reflectance images. The algorithm involves two main steps: initial burned candidates are identified by analyzing spectral changes around MODIS hotspots, and those candidates a...
Significance
Fires burn an area comparable to Europe each year, emitting greenhouse gases and aerosols. We compared burned area (BA) based on 20-m resolution images with a BA derived from 500-m data. It represents an 80% increase in BA in sub-Saharan Africa, responsible for about 70% of global BA. This difference is predominately (87%) attributed t...
Four burned area tools were implemented in Google Earth Engine (GEE), to obtain regular processes related to burned area (BA) mapping, using medium spatial resolution sensors (Landsat and Sentinel-2). The four tools are (i) the BA Cartography tool for supervised burned area over the user-selected extent and period, (ii) two tools implementing a BA...
This study provides a comparative analysis of two Sentinel-1 and one Sentinel-2 burned area (BA) detection and mapping algorithms over 10 test sites (100 × 100 km) in tropical and sub-tropical Africa. Depending on the site, the burned area was mapped at different time points during the 2015–2016 fire seasons. The algorithms relied on diverse burned...
Dependency on unsustainable energy sources like fossil fuels is at the stake due to their contribution to global warming and climate change. The pursue of development and exploitation of alternative, cost-effective and environmentally friendly energy sources like renewables energies is vital for the reduction of greenhouse emissions to the atmosphe...
A new supervised burned area mapping software named BAMS (Burned Area
Mapping Software) is presented in this paper. The tool was built from standard ArcGISTM
libraries. It computes several of the spectral indexes most commonly used in burned area
detection and implements a two-phase supervised strategy to map areas burned between two
Landsat multit...
El Foro de Ingeniería en Geomática y Topografía del Grupo de Trabajo de la IDEE, que agrupa a los Centros Universitarios españoles en los que se imparte esa titulación, ha elaborado este texto con la intención de que se sirva de ayuda y apoyo a la docencia a nivel universitario de una asignatura de introducción a las principales tecnologías y están...
Fire risk assessment should take into account the most relevant components associated to fire occurrence. To estimate when and where the fire will produce undesired effects, we need to model both (a) fire ignition and propagation potential and (b) fire vulnerability. Following these ideas, a comprehensive fire risk assessment system is proposed in...
Este trabajo consiste en la aplicación de técnicas de teledetección sobre imágenes lunares, con el objetivo de obtener información de las características superficiales mineralógicas de la Luna. Se describen el tratamiento de las imágenes obtenidas por la misión SELENE, desarrollada por la Agencia Japonesa de Exploración Aeroespacial (JAXA), así com...
This work consisted in the application of remote sensing techniques on lunar images with the aim of obtaining information on the superficial mineralogy features of the moon. It describes the processing of the images obtained by the SELENE mission, developed by the Japan Aerospace Exploration Agency (JAXA), and the results obtained in one particular...
This paper shows the results obtained in a research project from the University of the Basque Country (NUPV/08). The project was accomplished to carry out and produce biomass cartographic data from residues generated in the forest treatments of the main forest species potentially usable as energy resources in Bizkaia. A Geographic Information Syste...
A novel automatic burned area mapping algorithm for Mediterranean ecosystems based on Moderate-Resolution Imaging Spectroradiometer (MODIS) time series data is presented in this paper. This algorithm is based on a two-phase approach. The first phase detects the most severely burned areas, using spectral/temporal rules computed from dynamic temporal...
This paper presents results of the AQL2004 project, which has been develope within the GOFC-GOLD Latin American network of remote sensing and forest fires (RedLatif). The project intended to obtain monthly burned-land maps of the entire region, from Mexico to Patagonia, using MODIS (moderate-resolution imaging spectroradiometer) reflectance data. T...
La teledetecci?n se ha convertido en una herramienta de gran inter?s en la cartografia de las ?reas afectadas por los incendios forestales, especialmente a escalas regionales y globales debido a las ventajas que proporcionan las im?genes de sat?lite. Los sensores espaciales observan sistem?ticamente la superficie terrestre en condiciones homog?neas...
El objetivo de este trabajo consiste en diseñar un algoritmo para cartografiar de forma automática las áreas quemadas a partir de imágenes post-incendio. Se han empleado los denominados algoritmos multi-fase que consisten, en primer lugar, en identificar los píxeles semilla con alta probabilidad de que estén quemados, para posteriormente, partiendo...
This paper presents methods to generate fuel type maps from remote sensing data at a spatial and temporal scale adequate for operational fire management applications. Fuel type maps account for structural characteristics of vegetation related to fire behaviour and fire propagation. A fuel type classification system adapted to the ecological charact...
