Hyperspectral imaging takes a spectrum of light and divides the light into hundreds of narrow spectral bands. For example, Hyperion has 242 bands at 30m GSD.
Photogrammetry uses photographs from at least two different vantage points. It obtains depth and perspective because of separate points of observation.
Sentinel 2 has a total of 13 bands. Each band is 10, 20 or 60 meters in pixel size. This includes red, green, blue, near infrared and short infrared bands.
We list Landsat 8 bands as well as popular band combinations which includes coastal, blue, green, red, NIR, SWIR-1, SWIR-2, cirrus and two thermal bands.
A list of the 50 most iconic satellites put up into space to monitor our planet. We show the uses and types of satellites like weather and GPS satellites.
Selective availability is the intentional degradation of GPS signals. When selective availability was enabled, this added error horizontally and vertically to GPS signals.
As our population grows and climate is at risk, remote sensing of the environment solves large-scale environmental issues for the land, ocean and atmosphere.
