Remote Sensing is a generic term for types of satellite or high-altitude aviation imagery that contains bands outside of the visual spectrum, or uses a novel method of capturing images that the human eye would otherwise be unable to see.
Where we're going, we won't need eyes to see - Sam Neill, Event Horizon
NIR (Near-Infrared)
Many satellite imagery providers (e.g. Planet 0.5m) include NIR bands. NIR puts particular emphasis on plants and vegetation, and can be used to calculate A common method of analysis is to simply use the imagery as you would optical, but replace the "red" band (e.g. in Qgis) with the NIR data.
