It seems like the last "Improving the color" step is what gives most of the atheistic effects (by comparing the second last picture and the final result on the top). Unfortunately the explanation for that step is only a few sentences..

Bump the contrast and saturation and you'll be pretty close I reckon.

As someone who don't know how to use Photoshop, it's interesting to learn (as you said) that, most the difference is only contrast and saturation.

The final image just looked so much better than the second last one for me.

I had an idea to sort of automate this process or even a user aided wizard as a product but never to round to the mvp. Still an ok idea I think as satellite imagery on wall is great talking point. It can be beautiful, dramatic, always changing so makes for sets of images showing changes etc

Photoshop gives you a lot of tools to tweak beyond simple contrast and saturation sliders. The curves UI has been in it in some form since very early versions in the 90s. It lets you dial in a transfer function for each color channel (or luminance) as a bezier curve. The UI shows you a histogram so you can easily understand what's going on with the actual numerical values, avoid clipping, etc. There's plenty of smart tools in the more recent versions too.

Another simple but subtle advantage is you can do these corrections in a perceptual or near perceptual color space like CIELAB, rather than simple RGB. Particularly when you're pushing saturation this gives more natural looking outcomes.

Looks nice! I noticed that at the bottom of the page there is an e-mail sign up box that says: "Don't See Your Favorite Place? Know when we release new maps." Now I know e-mail sign up forms usually come canned in a bit of javascript, but it sure seems like it would help if people signing up could also include a place they would like to see. I'm not in the market for this kind of thing but I was hoping they would hav…

Oh cool! I guess I scrolled too fast or something. Thanks.

When I was a google intern in 2013 I downloaded the raw google maps satellite images for all of the United States. I stitched it together into one giant high resolution image. The plan was to get it printed big enough to cover an entire wall. That ended up being too expensive though and nothing ever happened.

Too expensive for you or for Google?
