We present an adaptive system for the automatic assessment of both physical and anthropic fire impact factors. The aim is to provide an integrated methodology exploiting a complex data structure made of SAR images and several other information sources to obtain a fire susceptibility map of a specific region of interest.
read moreThe Agustin Codazzi Geographic Institute (IGAC) of Colombia and UNOOSA recently signed a cooperation agreement making IGAC the newest UN-SPIDER RSO. IGAC has been promoting the use of space-based information within Colombia for a variety of purposes and has also been supporting UN-SPIDER in activities conducted in Latin America and the Caribbean. As an RSO, IGAC will continue to provide support in terms of experts towards the provision of technical advisory support to countries within the region and will contribute to capacity building efforts in this region.
El Instituto Geográfico Agustín Codazzi (IGAC) de Colombia y UNOOSA firmaron en el año 2011 un acuerdo de cooperación para establecer la Oficina Regional de Apoyo en Colombia. IGAC promueve en Colombia el uso de información obtenida desde el espacio para distintos propósitos y ha apoyado a ONU-SPIDER en sus actividades conducidas en América Latina y el Caribe. Como Oficina Regional de Apoyo, IGAC continúa ofreciendo expertos a ONU-SPIDER para su Asesoría Técnica a países de la región con el objetivo de contribuir en los esfuerzos de fortalecimiento de capacidades en la región.
The objective is to monitor vegetation recovery after the large fires of 2003 in Portugal using a time-series of MODIS Terra Enhanced Vegetation Index (EVI) data. Post-fire vegetation regeneration rate was estimated using Olson’s model. We attempted to model it as a function of fire history, including number of times burned prior to 2003. This study shows that satellite imagery can be very valuable for studying post-fire vegetation response, and this can contribute to a better understanding of wildfires, lead to improved management strategies for prevention, or even improve allocation of firefighting resources.
