In simple terms, remote sensing is the process of acquiring data or […] In recent decades, this area has attracted a lot of research interest, and significant progress has been made. Remote sensing is the acquiring of information from a distance. Remote sensing refers to the process of acquiring information from the Earth or the atmosphere using sensors or space shuttles platforms. Especially, it is used in computer vision, medical imaging, astronomy, remote sensing and so on. Image Classification techniques are used to categorize the pixels in the satellite data for differentiating the various earth features such as barren land, forests, roads, settlements, water bodies, rocks based on the spectral reflectance. JCR Impact Factor: 4.509. 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 (typically from satellite or aircraft). Le Moigne, N.S. Prior to the lecture I did some research to establish what image classification was and the differences between supervised and unsupervised classification.
