Farmland from space. Digitised Landsat image of a typical farm in Bedfordshire,England,showing land use. The boundaries of crop fields,broadleaf woodland,grassland,and a farmstead are demar- cated. Agricultural crops include barley,oilseed rape (red),and winter wheat (shades of brown,younger wheat is lighter in colour). The Landsat Thematic Mapper used here produces an image of high-resolution (30 metres). It records reflected radiation in 3 wavebands: near infra-red,mid infra-red and red. This produces the red,green and blue on the image,useful in determining plant type. Photographed by Landsat 5 on 12 June 1992,at an altitude of 705 kilometres | |
