Study Notes

Remote Sensing

Remote sensing is the method of collecting information about an object, place, or phenomenon without actual physical contact.
It involves collecting data without physically being in contact with the object or phenomenon.

Sensors

Sensors are devices used for data collection in remote sensing.
Examples of sensors include cameras and scanners.

Classification of Remote Sensing

Remote sensing can be classified into two categories based on the source of energy:
- Passive remote sensing: uses solar energy.
- Active remote sensing: uses artificial sources of energy.

Platform

A platform is the carrier on which sensors are fixed.

Classification of Remote Sensing based on Platform

Remote sensing can be classified into three categories based on the platform:
- Terrestrial photography: captures photographs of the earth's topography from the earth's surface.
- Aerial remote sensing: the continuous process of capturing data from an airborne platform.
- Satellite remote sensing: captures data from an orbiting satellite.
