| Preamble |
|---|
| Remote Sensing is the science of acquiring information about an
object or a phenomenon kept at a distance. Eyes and ears can only see and listen to a narrow band (visible wavelength of light) of the extremely broad electromagnetic spectrum and sound frequency (audible frequency). In artificial remote sensing, we aim to enhance the process by incorporating a broader information channel to gather more detailed data. It is a reflectance spectroscopy. Remote sensing is a powerful tool for studying landscapes. It involves extracting information from spectral images and then analysing them to understand various earth surface processes. A Geographic Information System (GIS) is software for mapping. All the related information can be gathered, plotted on the map, and then analysed using QGIS, open-source software. |
