You're making it out to be way more complicated than it actually is. A good example is that there is a certain type of mushroom that only grows out of wood buried in river sediment. So you use Google maps to look for where rivers have bends where wood would likely wash up when they flood. You need to actually visit a few sites in person in order to calibrate your satellite reading ability, but it doesn't take more than a couple days or require any specialized knowledge.
You can also download data on the soil types, trees, rainfall, temperature, forest fires, etc., but again even this just requires a couple days of googling and reading stuff.
I didn't say it couldn't be done. But I deal every day with cashiers who can't count money and there are tons of people who have no idea how to use Google maps. I spend a lot of a time at a library where I routinely watch library staff assist people who can't figure out how to get online -- by which I mean they are logged in and the browser has auto-opened for them and it isn't on the page they want and they have no idea how to get to what they want. And I see endless other examples of lack of basic computer literacy where library staff have to explain very basic things.
I am sure there are people who can do this. I just don't think it's all that many people in the grand scheme of things.
