When I was a senior in high school, I was lucky to able to volunteer under Dr. Eric Brown De Colstoun at NASA Goddard, checking error rates for tree cover estimates using Landsat data^. Many hours that fall spent trudging around parks and forests, looking at the sky through a PVC pipe. It still kind of blows my mind at how much is able to be gained from images where each pixel is 15mx15m of ground-level area (and, I believe, with an important component of Landsat 7&amp;#x27;s imaging system broken for most of its lifespan).&lt;p&gt;I also wasn&amp;#x27;t aware that Landsat program imagery had been made free to access a few years later. Nice.&lt;p&gt;^(A massive thank you to him, since I wouldn&amp;#x27;t have graduated without being able to participate in that project. And a massive apology for going on to get a fine arts degree.)</text></comment>
