Description
English: View of Corsica from the Landsat 7 satellite. This picture was built using data from the ETM+ instrument, by merging two datasets covering each half of the island. Bands 1, 2 and 3 (respectively blue, green and red) were combined to get a true-color image. Data from band 8 (panchromatic, visible + near infrared) was used as intensity value. Colors were then enhanced using an image manipulation program. Bands 1, 2 and 3 have a resolution of 30 m, and band 8 has a resolution of 15 m. Data was acquired on 2002-06-17. Most of the mountains thus lack snow, but névés can still be seen on highest peaks.
Français : Vue de la Corse depuis le satellite Landsat 7. Cette image a été obtenue à partir des données de l'instrument ETM+, en fusionnant deux ensembles de données pour couvrir toute la surface de l'île. Les bandes 1, 2 et 3 (correspondant respectivement aux couleurs bleu, vert, et rouge) ont été combinées pour former une image en couleurs réelles. Les données de la bande 8 (capteur panchromatique sensible à la fois aux couleurs visibles et à l'infrarouge proche) ont été utilisées comme valeurs d'intensité. Les couleurs ont ensuite été réajustées dans un logiciel de retouche d'image. La résolution des bandes 1, 2 et 3 (couleurs visibles) est de 30 m, et celle de la bande 8 est de 15 m. Les photos satellite ont été prises le 17 juin 2002. On peut constater l'absence de neige sur la plupart des montagnes corses, sauf quelques névés encore présents sur les plus hauts sommets.
