| Active ground-based remote sensing uses pulsed electromagnetic radiation sources such as lasers and radars to probe atmospheric structure. |
| These use remote sensing and instruments that can scratch away surfaces to analyse the geology of the Red Planet. |
| There are several possible new markets, such as remote sensing and space tourism. |
| As remote sensing relies heavily on interpretation skills, local experts may help with the interpretation. |
| A chlorophyll meter or remote sensing information also can be used to help determine the need for nitrogen. |
| These remote sensing technologies can also be used to distinguish GM from non-GM crops, and trace genetic pollution. |
