Remote Sensing
Remote Sensing is the art, science and technology of observing an object scene, or
Remote Sensing
phenomenon by instrument-based techniques.
Remote: because observation is done at a distance without physical contact with the object of interestwithout physical contact with the object of interest
Sensing: Detection of energy, such as light or another form of electromagnetic energy

Remote sensing data
Geospatial data acquisition (GDA): Collection, processing and analysis of data for various
Remote sensing data
, p g ypurposes:
- Water management- Land management- Resource management, etc.
Data :representations that can be manipulated by a computer
Information :interpreted data “GEO”: geodetically
