Remote sensing is the science and technology of obtaining information about objects from a distance and without physical contact.
This enables us to:
- Observe patterns and relationships which cannot be seen from the ground.
- Enables us to view invisible information that the human eye cannot perceive by using sophisticated sensors.
- Collect data for large areas of landscape.
- Repeatedly observe areas to detect change.
Remotely sensed data can take many forms from aerial photography to satellite imagery.
