[edit] Summary

Description
English: Satellite image of crops growing in Kansas, United States. Healthy, growing crops are green. Corn would be growing into leafy stalks by late June (when this photo was taken). Sorghum, which resembles corn, grows more slowly and would be much smaller and therefore, possibly paler. Wheat is a brilliant gold as harvest occurs in June. Fields of brown have been recently harvested and plowed under or lie fallow for the year. The circular crop fields are a characteristic of center pivot irrigation. The fields shown here are 800 and 1,600 meters (0.5 and 1 mile) in diameter. The image is centered near 37.4 degrees north latitude, 100.9 degrees west longitude, and covers an area of 37.2 x 38.8 km. The 'grid' in which the fields are laid out runs north-south/west-east and the dark angled line is U.S. Route 56. The image is aligned with the satellite orbital track, which is in a 98 degree tilted orbit. North is about 10 degrees counter-clockwise from up. The image is a false-color presentation made to simulate natural color. The 3 bands that were used are in the green, red, and near infrared parts of the spectrum. ASTER does not have a blue channel, so any blue that can be seen was created from the other bands.
Français : Image satellitaire de cultures poussant au Kansas (Etats Unis) à la fin du mois de juin. Les cultures en pleines croissance comme le maïs sont représentées en vert. Le Sorgho, moins avancé en cette saison, est plus pâle. Le blé est déjà doré et sera bientôt récolté. Les parcelles brunes ont déjà été moissonnées ou sont en jachère. La forme circulaire des champs est typique de l'irrigation à pivot central. Le diamètre de ces champs est souvent de 800 ou 1600 mètres, ils sont inscrit dans les "sections" de 1 mile américain de côté héritées du Public Land Survey System (article en Anglais). La ligne oblique qui traverse l'image est la Route Fédérale 56. L'image est alignée sur l'orbite du satellite ASTER e la NASAm qui a pris la photo. Cette orbite est, inclinée de 98 degrés par rapport à l'axe des pôles. Le nord est vers le haut, mais il fait un angle de 10 degrés dans le sens inverse des aiguilles d'une montre. L'image est en fausse couleurs, simulant les couleurs naturelles. Les trois longueurs d'ondes observées correspondent au vert, au rouge, et au proche infrarouge.
