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.
