Remote sensing refers to a set of technologies that allows us to "sense" or study the earth, other planets, and space objects indirectly. It includes aerial photography and photogrammetry, satellite imagery, global positioning systems (GPS), radar, sonar, and LIDAR (Light Detection And Ranging) technologies.
This extensive tutorial works through all the aspects of remote sensing including the history, image processing and interpretation, and various applications (among which are geologic, vegetation, urban and land use).
