I highly recommend this class with Professor Gebremichael. It covers a lot of useful topics in remote sensing and you learn some useful skills in finding data and analyzing it in R. Even if you don't know a lot going in the professor is really good at explaining and has good lecture notes. He is also just a really nice guy and he really cares about his students and wants them to succeed. Even with a virtual class, you could tell he was invested in our learning and passionate about the subject. Great guy and a great class.
