The spectral resolution describes the ability of a sensor to distinguish between fine wavelength intervals. Remote sensing systems record the reflected proportion of radiation in several separate wavelength ranges (so-called spectral bands or channels) at various spectral resolutions. The finer the spectral resolution, the narrower the wavelength range for a particular channel or band, the better different objects can be detected and distinguished. 3, record 1, English, - spectral%20resolution

La résolution spectrale décrit la capacité d'un capteur à utiliser de petites fenêtres de longueurs d'onde. Plus la résolution spectrale est fine, plus les fenêtres des différents canaux du capteur sont étroites. 4, record 1, French, - r%C3%A9solution%20spectrale

Importance de la résolution spectrale : si la résolution est élevée, on pourra mesurer de manière continue. Avec une résolution plus faible, les mesures seront discrètes (c'est le cas la plupart du temps) : les capteurs enregistrent des données dans un nombre limité de canaux. N'oublions pas qu'il n'existe pas un type unique de végétation, de roche ou de sol. Si la résolution (spatiale et spectrale) est suffisante, on pourra distinguer ces différences. Dans le cas du sol, il peut être particulièrement intéressant de connaître la teneur en eau d'un type de sol par rapport à un autre. 5, record 1, French, - r%C3%A9solution%20spectrale
