What is Remote Sensing (RS) ?

Remote Sensing can be summarised as:

-acquisition and interpretation of images from space and the air

-a major source of geographical data

-remote sensing includes techniques for data acquisition and processing anywhere on the globe at low cost

-repetitive and consistent update potential

-many image analysis systems contain sophisticated analytical functions

-interpreted data from a remote sensing system can be merged with other data layers in a GIS

Satellite Remote Sensing

Satellites provide nearly global coverage of the Earth with spatial resolutions and repetition rates that vary from one platform to another.

Traditional applications have been in earth resources, mapping and environmental monitoring, frequently in inaccessible regions of the world.

Remote sensing also includes the use of satellite data for estimating atmospheric water vapor, trace gases, aerosol particles, clouds, and precipitation.

In addition, satellite data are used to study the radiative and dynamical processes that affect the climate of the Earth. NASA undertakes applied research in this sector.

Videography is another form of remote sensing.
