 ====== Spectral signature ======
-The spectral signature of a surface is it reflectance, it mean the measurements wavelengths return by the object. It useful in [[english:glossary:remotesensing|remote sensing]] because each surface have his own spectral signature.
+The spectral signature of a surface is its [[english:glossary:refectance|reflectance]], i.e. the measurements in a specific wavelength returned by the object. It is useful in [[english:glossary:remotesensing|remote sensing]] because each surface have his own spectral signature. In reality, it is often difficult to retrieve this "pure" value of reflectance.
