ETUDES MULTISPECTRALES "IN SITU", COMPARAISON AVEC ENREGISTREMENTS MULT I SPECTRAUX = DES APPLICATIONS EN AGRONOMIE Colette Girard Institut National Agronomi que. France RESUMF L’étude des mesures de réflectance faites sur le terrain, montre que l’on peut identifier des cultures à partir de leur réflectance surtout avec des mesures faites à différentes périodes de végétation. Sur un enregistrement mu 11ispectraI en altitude on peut, en com parant certaines bandes spectrales (650-700nm, 800-890nm et 920-1lOOnm) i- dentifier les cultures. La comparaison de ces deux types de mesure est difficile. L’éner gie captée dans chaque cas n'est pas la même.Le recouvrement du sol par une culture est un élément important pour sa réflexion spectrale. Au-dessus de 15 I de la surface totale couvert par un végétal, un champ a une courbe réflectance de végétal. Enfin la structure du champ, le port, la forme de la culture sont des facteurs influant sur la réflectance. SUMMARY The study of crop reflectance measured on the fields shows that crop identification with the aid'of reflectance curves is possible. It is easier if measures done at different periods of growth are available. Mu 11ispectra I sensing from an aircraft might also be used for crop identification. Comparison of 650-700nm, 800-890nm, and 920-1lOOnm bands give good results. Comparison between the two types of measures is difficult becau se the energy sensed in both cases is different. Nevertheless it shows that for over 15 % of the area covered by a crop, the field reflectance is that of a crop. The field structure, the shape the foliar development of the crop have an effect upon the reflectance.
