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.
GOES and POES are both operational environmental satellites. But they actually share more in common such as their 40+ year legacy in space.
DigitalGlobe’s cutting-edge high resolution Worldview satellite carves out ridiculously crisp imagery at 31 cm in 8 spectral bands.
Despite popular belief MODIS is a satellite, it’s actually an instrument on-board a satellite. It has 36 bands, 250-1000 meter resolution and 2-day revisits.
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.
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.
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.
AVHRR (Advanced Very High Resolution Radiometer) spatial resolution is actually very coarse at 1.1 km. But its revisit times are “very high” at just one day.
Copernicus is the world’s largest and most ambitious Earth observation program in existence today with its Sentinel satellites taking center stage.
