<strong>Remote</strong> <strong>Sensing</strong><br />
<strong>Remote</strong> <strong>Sensing</strong> of Earth’s <strong>Hydrosphere</strong><br />
∙ Earth Resource missions (currently operational)<br />
∙ Sensor systems and characteristics applicable to water on earth’s<br />
surface and atmosphere<br />
∙ Internet-accessible satellite images and scientific studies<br />
•Student understanding of the science …<br />
Water in all its states (solid, liquid and gas) can be observed<br />
directly and/or indirectly from orbital platforms<br />
Mapping and <strong>Remote</strong> <strong>Sensing</strong> Basics<br />
∙ Examples of <strong>Remote</strong> <strong>Sensing</strong><br />
∙ Maps, coordinates, scales, measurements and proportions<br />
∙ Aerial Photography ... focal length and altitude ratios<br />
∙ Electromagnetic spectrum ... capturing and counting photons<br />
∙ Converting data to visual images (RGB)<br />
∙ Atmospheric Windows ... absorption and scattering effects<br />
∙ Passive and Active systems<br />
∙ Sensor Resolution ... spatial, spectral and temporal<br />
∙ Getting the most from the data ... digital signal enhancement<br />
