Remote sensing refers to the measurement or acquisition of information about an object or phenomena from a distance without physical contact by using devices or sensors mounted on some platform. Remote sensors collect data by detecting the energy that is reflected from Earth. These sensors can be on satellites or mounted on aircraft. Remote sensors can … Read more
The Global Positioning System consists of 24 satellites, that circle the globe once every 12 hours, to provide worldwide position, time and velocity information. GPS makes it possible to precisely identify locations on the earth by measuring distance from the satellites. GPS allows you to record or create locations from places on the earth and … Read more

Remote sensing- GIS and its application Remote Sensing Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation. In current usage, the term “remote sensing” generally refers to the use of satellite- or aircraft-based sensor technologies … Read more
Magnetic storm A magnetic storm is a period of rapid Magnetic Field variation. It can last from hours to days. Magnetic storms have two basic causes: The Sun sometimes emits a strong surge of solar wind called a coronal mass ejection. This gust of solar wind disturbs the outer part of the … Read more
