• Abstract:

  Wildfires are a major concern

  throughout the world, causing catastrophes and

  environmental losses. At the beginning of 2017

  Chile was affected by large-scale wildfires that

  lasted for several days. The objective of this

  work was to compare MODIS, Landsat 8/OLI,

  and Sentinel 2 images from a region between

  Concepcion and Valparaiso in Chile during the

  wildfires cases in 2017. The MODIS sensors

  on-board TERRA and AQUA satellites, have a

  daily temporal resolution that is indispensable

  for detection and monitoring wildfires. Landsat

  8/OLI has a better spatial resolution but 16-

  days temporal resolution. Sentinel 2 presents

  an even better spatial resolution and 5-days

  temporal resolution if considered both satellites

  of the series. Besides the presentation of the

  images of the daily event monitoring, some

  results obtained by fire detection algorithms for

  specific satellites/sensors are also presented.

  The satellite images associated to the detection

  algorithms allow the identification and spatial

  distribution of wildfires in a near real time, thus

  enabling the management and continuous

  monitoring of territorial extensions grids.
