Obviously this is just for fun, but I am a bit disturbed about similar projects that try to gain some meaningful insights out of vast public data sets without the slightest attention paid to the quality of the data used. It doesn’t matter how much processing you do or how clever your algorithms are if the underlaying data is inaccurate, out of date, inconsistent, non-normalized, incomplete, etc. No dataset is perfect, but at least take some time to address it.

The color of a lake in satellite view depends on the satellite's viewing angle (which depends on the satellite's trajectory and the lake's location), the angle of the sun (which depends on the same things plus the time and date the image was taken), the weather, the satellite's sensors (false color is a thing), and how the images are processed before publishing. Overall I think it's almost impossible to estimate the…

Yeah I stopped taking this post seriously when I read this sentence: > I fetched the satellite image tile for the zoomed-in region of each lake center and read a single pixel at the center of the tile, which should give us an idea of the lake’s color

Well, I mean, it's an idea.
