Remote Sensing
Announcement


In present practices for the acquisition of information, the expression of remote sensing is usually referred to make use of satellite or aircraft sensor technologies to discover and sort out the information on the earth surface, atmosphere and oceans, based on disseminating signals. Satellite communication complements the Satellite remote sensing data products with certain capacity. The satellite remote sensing data products help in the reckoning, compatibility, accessibility, and understandability of the earth observations as well as identifying the position of the earth terrestrial and Polar Regions. Remote sensing technology has been used to oversee the earth's surface over a variety of different wavelengths.

To date, however, there is no definitively processed long-term land data records generated and those that are publically available are subject to scientific debate. Consequently, the EOS’s series of satellites, science components, and a data system is called Earth Observing System Data and Information System (EOSDIS) for the interdisciplinary studies of earth system science and associated services. Pakistan lies in the south Asian region, where the reliance on ground data is not sufficient for drought monitoring. This is due to the lack of reliable and complete data and proper information network systems, and the lower availability of weather-stations in the region like Pakistan.

Satellite remote sensing is a technology for condensed acquisition of spatial data and extraction of information’s. The Satellite remote sensing has been extensively used over the long-ago 20 plus years for the land cover changes, regionally and globally, involves the use of both systems and algorithms in order to record information about the surface of the Earth from a remote location. The principles of remote sensing results from the characteristics and interactions of electromagnetic radiation (EMR) from source to sensors are based on a) the source of energy and the type as well as amount of energy it provides,?b) the absorption and scattering effects of the atmosphere on EMR, c) the mechanisms of EMR interaction with Earth surface, and finally, d) the nature of sensor response, determined by the type of source.
