Lecture 5
Sensor Platform used 
Ground based Remote Sensing: A wide variety of ground based platforms are used in remote sensing. Some of them are hand held spectroradiometer, and scatter meter. 
Airborne Remote Sensing: Mostly used platforms for sensors are flight, unmanned aerial system (UAS) at desired height. 
Satellite Remote Sensing: Carrier of the sensors is the satellite which may be placed in low earth orbit (LEO), at height earth ranging from 160 to 2000 km or geostationary earth orbit (GEO) at a height more than 30,000 km away from earth surface.

Lecture 8 Geographic Information System (GIS) Geographic information system (GIS) is defined as a powerful set of computer-based tools for collecting storing, retrieving at will, and transforming and-displaying spatial him from the real world for a particular set of purposes. GIS consists of (i) An extensive database of geographic information involving both positional data about land features and descriptive / non-locational data about these features at different points of time; and (ii) Sets of programmes of applications, which enable the data to be input, assessed, manipulated, analyzed and reported.           The GIS history dates back 1960 where computer based GIS have been used and their manual procedures were in life 100 years earlier or so. On introduction of and spread of personal computers in 1980’s, exponential growth of GIS technology took place. However, potentiality of GIS is realized in the recent past and now it ...
