I am hoping to expand my (biology-focused) research to include satellite data. For this, I'd need satellite imaging that includes multiple values in the visible spectrum (specifically, above 490nm) and extends slightly into the infrared (710nm). I have tried MERIS and Hyperion, but the resolution was insufficient (my area of interest is a lake ~300m x 55m). Does anything like this exist, and is it freely available for research use?

1I would also try asking on the Open Data Stack Exchange. You may have luck there.– lambertjApr 30, 2019 at 15:08

Didn't say where specific area are you looking for ?– PROBERTApr 29, 2020 at 12:23

Consider WorldView 2 or 3, with 0.5 m spatial resolution and including red-edge and near-infrared bands. However, Worldview images are proprietary data from Digital Globe and must be purchased.

Thank you. The spectral bands of Worldview seem too wide for my calculations (ideally I'd prefer measurements at known wavelengths rather than a range). Would you happen to have any other suggestions?– LauraMay 1, 2019 at 13:03

Indeed, WV3 spectral bands are rather wide compared to true hyperspectral imagers. I believe no true hyperspectral instruments (with ~5 nm spectral band width) are currently carried on a satellite. There are some airplane-carried hyperspectral sensors though, such as APEX sensor, or AVIRIS. May 1, 2019 at 13:37
What about Sentinels of European Commission. We use the to identifie time of harvest, areas of snow, fire... Resolution is 10×10 meters. They take pistures in 9 spectrums.

Just neet to register and you got all data series fro couple of years. And most important, everthing is free.

Sentinel-2 is neither high-resolution or hyper-spectral. Apr 29, 2020 at 12:33
