Description= Satellite image of crops growing in [[Kansas]], [[USA]]. 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 [[:en:center pivot irrigation|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 [[w: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. [[:en:Advanced Spaceborne Thermal Emission and Reflection Radiometer|ASTER]] does not have a blue channel, so any blue that can be seen was created from the other bands. |
