Landsat satellites circle the globe, recording data in 11 different wavelengths. The individual wavelength bands can be combined into color images, with different combinations of the 11 bands revealing different information about the condition of the land cover.For complete transcript, click here.Watch this video on the NASA Goddard YouTube channel.This video is also available on our YouTube channel. Landsat satellites circle the globe every 99 minutes, collecting data about the land surfaces passing underneath. After 16 days, the Landsat satellite has passed over every spot on the globe, and recorded data in 11 different wavelength regions. The individual wavelength bands can be combined into color images, with different combinations of the 11 bands revealing different information about the condition of the land cover.The data for this video was collected by Landsat 5 on November 10, 2011. Still image of South Florida based on Landsat data in the visible wavelengths (blue, green, and red bands). The data was collected by Landsat 5 on November 10, 2011. Still image of South Florida based on Landsat data in the visible and near-infrared wavelengths (green, red, and near-infrared bands). The data was collected by Landsat 5 on November 10, 2011. Still image of South Florida based on Landsat data in the visible, near-infrared, and shortwave-infrared wavelengths (green, near-IR, and shortwave-IR 2 bands).
