- What is Remote Sensing?
Remote sensing is the “science and art of obtaining information about an area through data acquired by a device that is not in contact with the area under investigation" (Lilles and Kiefer, 1994). Simply, remote sensing is the study of one location from another.
- How does Remote Sensing work?
An optical satellite sensor measures the amount of energy, as light, that comes from the Earth’s surface. The signal is then interpreted by a scientist.
- What are the steps involved in putting a remote sensing satellite into orbit?
The steps are Pre-launch, launch and post launch/operations.
- How long does it take to launch a satellite, from idea to lift off?
The pre-launch phase for many satellites takes nearly a decade. Specifications must be agreed upon, a sensor and satellite need to be designed, tested and calibrated.
- What satellites are up there and what can they do?
Landsat – land and coastal habitat cover, Sea-Surface Temperature (SST)
SeaWiFS – ocean color
MODIS – ocean color and SST
AVHRR – SST
