Agricultural research. Satellite image of fields containing test crops at Lethbridge Research Centre in Alberta, Canada. The different crops have different colours according to their thermal properties, which are registered by the infrared channel of the satellite's remote sensing equipment. The data for this 2.5-metre-resolution image were obtained from the Spot-5 Earth observation satellite, which was launched in 2002. The image covers an area approximately 4 kilometres wide.
