Study Notes
What is Remote Sensing?
- Remote sensing is the acquisition of information about the Earth's surface through the detection and measurement of radiation reflected or emitted by the Earth's surface.
Interactions in Remote Sensing
- Electromagnetic radiation (EMR) interacts with objects on the surface of the Earth in remote sensing.
Basis for Differentiation
- The basis for differentiating objects using different bands in remote sensing is the unique spectral signature of each object.
Re-radiation in Remote Sensing
- The object re-radiates the electromagnetic radiation it absorbs, which is then detected by remote sensing devices.
Object Response to Wavelengths
- Different objects respond differently to the same wavelength in remote sensing due to their unique physical and chemical properties, resulting in varied spectral signatures.
