L'ensemble de données MOD14A2 V6.1 fournit des composites de masques d'incendie de huit jours à une résolution de 1 km. Il contient la valeur maximale des classes de pixels individuelles au cours de la période de composition. En plus du masque d'incendie, une couche d'informations sur la qualité associée est également fournie.
Bits 0 à 3 : classes de pixels du masque d'incendie
1 : Non traité (obsolète ; non utilisé depuis la collection 1)
2 : Non traité (autre raison)
3 : Pixel d'eau non incendiaire
4 : Nuages (terre ou eau)
5 : Pixel de terre non incendié
6 : Inconnu (terre ou eau)
7 : Incendie (fiabilité faible, sur terre ou sur l'eau)
8 : Incendie (confiance nominale, terre ou eau)
9 : Incendie (niveau de confiance élevé, terre ou eau)
QA
mètres
