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?
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.
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.
