Introduction to Satellite Imaging Technology and Creating Images using Raw Data Obtained from Landsat Satellite

This paper aims at presenting various satellite imaging techniques. The paper also includes satellite sensors, their resolution, the format in which they store data, the bands which they use and their applications in satellite imaging technology. The concept of color composite images has also been introduced. Through this paper we intend to present a logic for creating images using raw data obtained from landsat satellite. For this context we have taken an example of KILAUEA VOLCANO, HAWAII image, taken on 23 MAY 2001 by Landsat-7 satellite. After looking at the output some important conclusions have been made. Later, few limitations associated with remote sensing have been listed. Keywords: BIL, BIP, BSQ, EM spectrum, ETM+, FCC, NCC, RS.
