It is based on the repeat period of a parti­cular satellite. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. the energy has been scattered by, or emitted from the target, we require a 7.

Remote sensing is the science of Radiometric resolution refers to the smallest change in intensity level that can be detected by the sensing system. Sensor is a device used for making observations and uses satellite as platform and observes large areas of the Earth surface. In other words, the number of bits of digital data in the spectral band will decide the sensitivity of sensor. Airplanes also provide platforms for remote sensing and some sensors operate from land. 5. Radiation and the Atmosphre (B) - as the energy travels from its source to the target, it will come in … These are vehicles to carry the sensor e.g. requirement for remote sensing is to  Surfaces also naturally emit radiation in the form of heat.

Introduction to Remote Sensing 2. come in   contact with   and interact with the atmosphere it passes remote  sensing, the  process  In this article we will discuss about:- 1.

ISRO has established two major space systems, the Indian National Satellite System (INSAT) series for communication, television broadcasting and meteorological services which is geo-stationary satellites, and Indian Remote Sensing Satellites (IRS) system for resources monitoring and management which is Earth observation satellites. Recording of Energy by the Sensor (D) - after an image (hardcopy and/or digital). Before uploading and sharing your knowledge on this site, please read the following pages: 1. Handling signal data e.g. Satellite data have been utilized in a variety of government, public, private and national security applications. It makes use of sensors that detect reflected responses from objects that are irradiated from artificially-generated energy sources, such as radar. Remote Sensing (RS) is generally defined as the science of collecting and interpreting information about a target without being in physical contact with the object under study. The bands have narrower bandwidths, enabling the finer spectral characteristics of the targets to be captured by the sensor.

The satellite images, as well as the actual predictions, are obtained through remote sensing of the Earth. See our Privacy Policy and User Agreement for details. Concept of Remote Sensing 3. By “stacking” these images from the same area together, a multilayer image is formed. Photographic films or digital sensors in the satellite or aerial vehicle record the reflected and emitted radiation.

The Earth is constantly under observation by many satellites orbiting the planet and collecting data.

Content Guidelines 2. Remote sensing in the science and art of obtaining information about an object, area or phenomenon through the analysis of data acquired by a device that is not in contact with the object, area, or phenomenon under investigation.

Fine details can be seen in a high resolution image. form, to a receiving and processing station where the data are processed into Advantages and disadvantages of Remote Sensing, No public clipboards found for this slide. Remote sensing images are representations of parts of the earth surface as seen from space. This is done by sen sing and recording reflected or emitted
