Application of Google Earth Engine in the preliminary analysis of fire severity in the Iberá National Park and Reserve, Argentina

“…Likewise, despite being an area that is protected or with greater restrictions in terms of the anthropic practices that are conducted there, it does not guarantee that fires will be avoided. Vasco-lucio et al (2022) state that fire severity, understood as the ecological change caused by this disturbance, can be assessed from direct observation of damage levels or from remote sensing techniques based on changes in the reflectivity of burned areas (Montorio Llovería et al 2014). As opposed to visual estimation in the field, which is highly costly in time and money, remote observation provides information with a large spatial coverage, quickly and continuously (Patterson & Yool, 1998), so it is important and should be constant the search for indexes, models and techniques that allow the correct estimation of severity with spectral information (Montorio Llovería et al 2014).…”

In this regard, the use of Google Earth Engine has been notably extended in recent years, since it allows the processing required for the study of fire severity in a fast and efficient way (Anaya et al 2018;Smichowski et al 2022, Long et al 2019Wang et al 2022).…”

Análisis De Incendios Forestales en Pajonales Andinos Utilizando Sistemas De Información Geográfica Y Teledetección, Macari – Puno

“…Los efectos del fuego referente a la respuesta de la vegetación es muy dependiente de la severidad del mismo (Veraverbeke y Hook, 2013), que es consecuencia de la intensidad con que se ha quemado; se puede definir la severidad del incendio como el grado de cambios que el fuego induce en el medio , o cuando el fuego afecta al ecosistema (Montorio Llovería et al , 2014).…”
