This webpage contains invited talks, articles, and resources available on Internet, on few select technology related to Remote Sensing :
The Imaging, Image Processing , Geographical Information System and Global Positioning System.
Remote Sensing is a technology of acquiring information (spatial, spectral, temporal), about materials, objects, areas, or phenomenon, observed on Earth or other planets or the entire Universe using instruments/sensors located at a distance not having direct contact. A bit of history about remote sensing is stated below.

*
The technology of modern remote sensing began with the invention of
the camera more than 150 years ago.
*
The idea of looking down at the Earth's surface emerged in the 1840s
when pictures were taken from cameras carried in the tethered
balloons for purposes of topographic mapping.
*
During first World War (1914 -18), the cameras mounted on airplanes
provided aerial views of fairly large surface areas that proved very
useful in military reconnaissance.
*
After World War II, in 1946, V-2 rockets acquired from Germany were
launched to high altitude contained cameras that took pictures as
the vehicle ascended.
*
The aerial photograph remained the single standard tool for
depicting the surface from a vertical or oblique perspective until
the early 1960s.
*
Then emerged the space program : in 1957 the Sputnik I (USSR) and
in 1958 the Explorer I (USA), were the first two Earth-orbiting
satellites acquired photographs. Since then many earth observation
satellites were launched owned many nations for both civil and
military need.
*
Only few countries, USA, France, India, and Israel have highly
efficient commercial Earth Remote Sensing programs. They offer image
resolution 1 meter and less. More importantly, they regularly
supplement the space segment with new satellite and hold the
positions as the primary suppliers of space data.
*
Many other countries, Korea, Russia, Italy, U.K., JAPAN, Malaysia,
Taiwan, and Thailand also have high resolution satellites mostly for
their own need. The launch, orbit and Imaging characteristics of
these satellites are indicated below. These satellites have
resolutions 2.5 to 1 meter.
