Recommended Posts

The visible and sudden growth and of GIS services  in the 20th century has been brought up by the innovative upsurge in the technological realms, computer hardware and software,  advancements in computer science and engineering along with the potential rise of  latest remote sensing  technologies  in space observation.  In general terms, remote sensing refers to the activities of recording or closely observing and registering or sensing objects or natural events at remote or distant places. Remote sensing can be termed as the science that deals with the derivation of specific information about an object by using sensors without physically contacting the object in observation. Hence we can say that remote sensing differs from in situ sensing of objects without physically touching the objects of measurement. Remote sensing becomes very important branch of GIS services.
