1. Navigate a Better Tomorrow with Navigation and Remote Sensing Technology We always have a question in our minds: how can a weather forecast be declared early?? Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance. Remote sensing is used in numerous fields like geography ,military, intelligence & in many fields. Technology of remote sensing is a concept of satellite monitoring the earth’s surface at high altitude to collect vital information of earth. The remote sensing technology enables us to switch over to alternative sources & creates awareness of the environment. Laser and radar altimeters on satellites have provided a wide range of data. They may also be used to detect the emission spectra of various chemicals, providing data on chemical concentrations in the atmosphere. Remote sensing allows researchers to follow up & monitor in defining relevant measures of environmental management & assess their impacts. Remote sensing technology is the fuel behind all necessary estimated data collected by remote sensing technology of earth’s surface & switch over alternate sources & create awareness of the environment.The skilled scientists transform data into information from data received from remote sensing technology for betterment of society & scientific community. Remote sensing & navigation research lab set up academia in collaborations with world renowned research institutes to pursue higher studies in this field. Special cameras collect remotely sensed images, which help researchers sense things about the Earth. Remote sensing allows coverage of very large areas which enables regional surveys on a variety of themes & identification of extremely large features.Remote sensing allows repetitive coverage which comes in handy when collecting data on dynamic themes such as water, agricultural fields. Remote sensed data can easily be processed & analyzed fast using a computer & data is utilized for various purposes. Remote sensing allows for a map revision at a small to medium scale which makes it better,f ast & cheapest. By remote sensing it is easier to locate floods or forest fire that has spread over a large region which makes it easier to plan a rescue mission easily and fast. Remote sensing is a relatively cheap & constructive method for reconstructing a base map in absence of detailed land survey methods. Remote sensing allows for easy collection of data over a variety of scales & resolutions. Remote sensing allows in large space & coverage of large areas. There is no limitation on the extent of information that can be gathered from a single remotely sensed image.

2. Remote sensing is of two types - - Active sensor . Passive sensor. Remote sensing plays a huge role in development of many technologies like world mapping. They can be used in - Forestry Weather Agriculture Surface changes Remote sensing is one of the top technologies in the present era.
