Remote Sensing

Remote Sensing is a combination of techniques, tools and interpretive resources that allow to extend and enhance the capabilities of the observer providing qualitative and quantitative information on objects at a distance, and then on the surrounding environment.

Data collect from satellite images depends on the characteristic of the sensor, such as spatial resolution, spectral resolution, radiometric resolution and temporal resolution.

Spatial resolution refers to the size of the smallest possible feature that can be detected

risoluzione

Spectral resolution is the number and dimension of specific wavelength intervals in the electromagnetic spectrum to which a sensor is sensitive.

The radiometric resolution of an imaging system describes its ability to discriminate very slight differences in energy

The temporal resolution of a remote sensing system is the ability to collect imagery of the same area at different periods
