Storm Prediction Center Severe Weather (SVRGIS) Geographic Information System (GIS) applications are becoming increasingly popular in many organizations, including the federal government. Emergency operations have taken advantage of these capabilities. “GIS can be beneficial in many ways, but in the simplest of terms, it connects people to information through geography. Government can use GIS to store, manage, and access information about its facilities, people, and environment. It gives government officials a way to visualize data that helps them make decisions about project planning and economic development.

As per current scenario in Chhattisgarh state there are several environmental problems which creating environmental imbalance. Few of the prominent problems are continuous increase of temperature due setup of power plants, improper management of waste, sewerage problem, air pollution, improper management of residential colonies, water wastage, land misuse etc. These problems can be rectified up to certain extent with the use of remote sensing satellite from which data can be received and analyzed to find the proper solution of environmental problem to make environmental problem free state. Most of the problems cover large geographical areas that will generate various local problems also in which GIS provides a best tool to proper handle. Establishment of Power plants are the main reason of thermal imbalance in Chhattisgarh which can be monitored and controlled by GIS data's.Keywords

An antenna is transducer, an impedance matching device, a radiator and a sensor of electromagnetic waves. It is essential device/element in all types of communication and radar systems. It can be considered as a source of electromagnetic wave. In this research paper an attempt has been made to study the characteristics of major antenna using frequency from 750MHz to 850MHz. In this experiment as well as research ATS-B Antenna system trainer is utilized. An antenna (or aerial) is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receivers. In transmission, a radio transmitter supplies an oscillating radio frequency electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves(radio waves). In receptions, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage as its terminals, that is applied to a receiver to be amplified. Typically an antenna consists of an arrangement of metallic conductors (elements), electrically connected to the receiver or transmitter. As oscillating current of electrons forced through the antenna by a transmitter will create an oscillating magnetic field around the antenna elements, while the change of the electrons also creates an oscillating electric field along the elements. Antenna can be broadly classified by the directions in which they radiate or receive electromagnetic radiation. They can be isotropic ,omni-directional or directional. An antenna is chosen for a particular application according to its main physical and electrical characteristics. Further an antenna must perform in a desired manner for the particular application. An antenna can be characterized by the following key factors , not all are applicable to all types of antenna. Main characteristics of an antenna are : radiation resistance, radiation pattern, the bandwidth etc. Further it has been found that graph of antenna polar plot which describes about antenna characteristics. Antenna are essential components of all equipment that uses radio. They are used in systems such as radio broadcasting, broadcast television, two-way radio, communication receivers, radar, cell phones, and satellite communication, as well as other devices such as garage door openers, wireless microphones, Bluetooth enabled devices, wireless computer networks, baby monitors, and RFID tags on merchandise.
This paper introduces antenna theory and discusses various antenna types and applications. The basic equations and principles of antenna theory are presented. Five different types of antennas are introduced: dipoles and monopoles, loop antennas, microstrip antennas, helical antennas, and horn antennas. The characteristics of each type of antenna are given.
